Recent earth tremors in Sri Lanka
– a critical review in relation with such activity in Tamil Nadu and the orogenesis of Himalayas based on a new theory of cratons and mobile belts in the Indian peninsular
By DULIP JAYAWARDENA
Former Director Geological Survey Department and retired Economic Affairs Officer, United Nations ESCAP
There were recent reports of earth tremors in the Buttala and Wellawaya areas in Sri Lanka and statements made by local earth scientists failed to give any scientific explanations as regards such activity.
An attempt is made to explain such activity in relation to seismicity in Sri Lanka compared to Tamil Nadu as well as the orogenesis of the Himalayas in relation to a new theory of cratons and fold belts in India and its extrapolation to Sri Lanka.
There was a news item in the local media that if a major earthquake occurs in the Himalayan region there will be tremors felt in Colombo as well as in Jaffna.
Historical seismicity in the Himalayan region has been analysed and its slip potential in the 21 Century recorded (Rodger Bilham roger.bilham@clorado.edu ).
The seismicity of Sri Lanka and Tamil Nadu are compared to understand mountain building in the two regions as Sri Lanka resemble crystalline metamorphic rocks of South India.
It is recommended that the theory cratons and mobile belts that has been postulated in India focusing on the Tamil Nadu region be extended to Sri Lanka to explain present earth tremors in Buttala and Wellawaya areas.
COMPARISON OF ALTITUDES AND SEISMIC RECORDS BETWEEN SRI LANKA AND TAMIL NADU
The highest mountains in Sri Lanka are Pidurutalagala (2524 metres msl), Kirigalpotha (2396 metres msl), and Samalakanda – Adam’s Peak (2243 metres msl)
As compared to Sri Lanka the heights of 77 mountains range from 2695 meters msl to 522 metres msl from the Indian Peninsular.
Tamil Nadu, which is a part of Peninsular India, compared to the highest peneplain of Sri Lanka (Wadia 1945), has three mountains namely Anamuda (2395 metres msl ) , Meesapullimala (2640 metres msl) and Kolabetta (2629 metres msl) -Wikipedia.
Accordingly, it is evident that the highest mountains in Sri Lanka can be closely related to those of Tamil Nadu subject to the same orogenesis or mountain building.
SEISMIC HAZARD ANALYSES FOR STATE OF TAMIL NADU SOUTH INDIA
A study by G. P. Ganapathy Assistant Professor, Centre for Disaster Mitigation and Management VIT University Vellore 632 014 Tamil Nadu India seismigans@yahoo.com and Rajaratnam S. Professor, Centre for Disaster Mitigation and Management, Anna University Chennai 600 025 Tamil Nadu, India ( drrajarathnam@yahoo.com ) have extensively analyzed seismic potential sources of Tamil Nadu State and are summarised in Table 2 of their paper titled, “Seismic Hazard Analyses for Tamil Nadu State: A Deterministic Approach “and published in the Jour. Engr. Geol. Vol.XXXV1 NO1.4
Tamil Nadu State covers 130 ,058 sq. km approximately twice the size of Sri Lanka which encompasses only 65 000 sq. km. Figure 1 gives a large number of lineaments which are seismic prone and it is interesting to note that such lineaments especially in the South Block may extend to Sri Lanka and Figure 2 indicate identified seismic potential sources in this block.
SEISMIC POTENTIAL SOURCES OF TAMIL NADU
Table 1 of the above research paper analyses seven sources seismic potential sources with lengths varying from 315 km to 42 km with cumulative number of earthquakes ranging from 5 to 1 with magnitudes varying from 6.0 to 5.0 (M) observed from historical /instrumental earthquakes and peak ground acceleration (PGA) in g determined using m varying from 0.212 to 0.078 . It is noted that PGA is high in earthquakes with magnitude 6.0 and low in magnitude 3. Further PGA in Chennai, Coimbatore, Salem, Madurai and Tiruchirappalli cities varies from 0.107g, 0.133g, 0.012g ,0.77g and 0.113 g respectively. It is noted that the southeastern part of the State shows high values because of a high earthquake data for the years 1800 to 2004 It also explains that the southern part of the State which may extend to Sri Lanka shows comparatively low seismic hazards.
SEISMIC RECORDS AND POTENTIAL OF SRI LANKA
It is reported that Sri Lanka had no seismic records up to 1800. However from the period 1615 to 1800 earthquakes were reported close to Sri Lanka in the northern Indian Ocean and Coimbatore- Nilgiri Hills. (Seneviratne H.N et al ( DOI :http://doi.org/10.4038/engineer.v53i2.7412)
Newspaper reports are available in the National Archives, Sri Lanka in 1882 ,1924, 1938 and 1944(Ceylon Observer) on earthquakes that had occurred during these years. However no deaths have been reported although there was damage to property (Gunasekera K.W (2000) Sunday Observer ,p34)
Seismic records from 1909 to 1992 were from a seismograph installed in 1909. However, no data are available since 1992 as it was not fully functional.
It is reported that from the year 1823 to 2010 earth tremors and earthquakes in Sri Lanka varied from 5.9 to 3.7 on the Richter Scale and most of such tremors were recorded in the Comorin Ridge Failed Mannar Rift Zone (Seneviratne et.al).
Sri Lanka has been identified as a Mid Plate Platelet lying between Antarctica -India -Africa and Madagascar ( Curry 1984 adopted by Crawford (1974 )and Katz (1978).
In 1823 there was an earthquake of 5.8 Magnitude at Mandawela , in close proximity of Colombo with coordinates 7deg. Lat. and 80 deg. Long. There were no deaths but damage to property were recorded. There was also an earthquake of 5.9 Magnitude at Lat. N 6.5 and Long 79 E close to Kurunegala.
It is interesting to note that Sri Lanka within a latitude of 7.8731 deg. North and 80.7718 East had 18 earthquakes or tremors between the period 1823 to 2010 a period of 187 years. However, the number of tremors of insignificant nature during this period was 670.

- Fig. 2. Map of Vijyana Complex with locations of sampling, edited after Kroner et al 2013. The tectonic mixed zone between the Highland Complex and the Vijayan Complex is highlighted as light-grey in colour.
The Geological Survey and Mines Bureau (GSMB) commissioned three seismometers, one at Pallekelle in year 2000 (PALK) connected to the Global Seismic Network (GSN)and the others in 2010 Mahakandarawa (MALK) connected to GEOFON) Network and Hakmana (HALK)connected to GEOFON (Geo-Network operated by Germany).
It is of importance that a network of seismometers be established in Colombo and the Western Province and a network of seismometers covering the entire Island to establish relationship between earthquakes and development activity accelerated recently in Sri Lanka. (Senaviratne H.N. et. al. 2020)
It has also been revealed that an earthquake of magnitude 6.9 (475-year return period) along the Mannar Rift Zone identified earlier in this report.
SRI LANKA HAS THE LOWEST GRAVITY RECORDED IN THE WORLD
The European Space Agency (ESA) carried out a four-and-a-half-year Gravity Field and Steady – State Ocean Circulation Explorer (GOCE) mission to learn what constitutes the surface beneath the Earth and discovered that the lowest negative gravity was south of Sri Lanka.
A geoid is the equipotential surface that coincides over the oceans with the same sea level. It is noted that the earth becomes flattened around the equator and the distance from equatorial areas to the center of the Earth is more than from the poles to the center. (Roar media Sachith Mendis (https://roar.media/english/life/reports/sri-lanka-least-earth-place-world )
It is also revealed that launching of space satellites will be much cheaper due the low gravity and due to no land surface directly south of Sri Lanka.
EARTHQUAKE OF 1615 IN SRI LANKA
An earthquake of magnitude 8 or 9 on the Richter scale was reported on 14 April 1615 evening offshore that caused extensive damage in western part of the Island. The worst hit area was Colombo and 2 per cent of Colombo Fort was destroyed. It has been reported that nearly 200 houses were destroyed with nearly 2000 casualties. Accordingly, moderate sized earthquakes cannot be ruled out in Sri Lanka. (Muhandiram P. M. S. S. B. <https: loes18.wildapricot.org/article _earthquakes-text= According to this document2 % of Colombo Fort got destroyed.
GRAVITY MAP OF SRI LANKA
A Gravity Map of Sri Lanka was compiled and produced in 1975 by the Geological Survey Department (present GSMB) on the scale of 1: 1. 000,000 by T. Hatherton, D. B. Pattiarachchi and V. V. C. Ranasinghe with an appendix by R.B. Evans.
A total of 1,170 points were established covering the whole Island in respect to 19 base stations and about 87 per cent of observations where in areas less than 150 meters msl.
The horizontal distance and heights of the 1971 gravity observations were from 1 -inch topographic maps covering Sri Lanka.
Most of these gravity stations were tied up with the trigonometrical survey stations of the Survey Department. When these stations were opened it was revealed that there was movement due to upliftment.
A contour map of complete Bouguer (gravity anomaly corrected to the height of its measurement) anomalies with the locations of gravity observations was produced.
The gravity map has revealed a negative gravity low on the Highland -Vijayan boundary in the east of Sri Lanka.

The heart-friendly health minister
by Dr Gotabhya Ranasinghe
Senior Consultant Cardiologist
National Hospital Sri Lanka
When we sought a meeting with Hon Dr. Ramesh Pathirana, Minister of Health, he graciously cleared his busy schedule to accommodate us. Renowned for his attentive listening and deep understanding, Minister Pathirana is dedicated to advancing the health sector. His openness and transparency exemplify the qualities of an exemplary politician and minister.
Dr. Palitha Mahipala, the current Health Secretary, demonstrates both commendable enthusiasm and unwavering support. This combination of attributes makes him a highly compatible colleague for the esteemed Minister of Health.
Our discussion centered on a project that has been in the works for the past 30 years, one that no other minister had managed to advance.
Minister Pathirana, however, recognized the project’s significance and its potential to revolutionize care for heart patients.
The project involves the construction of a state-of-the-art facility at the premises of the National Hospital Colombo. The project’s location within the premises of the National Hospital underscores its importance and relevance to the healthcare infrastructure of the nation.
This facility will include a cardiology building and a tertiary care center, equipped with the latest technology to handle and treat all types of heart-related conditions and surgeries.
Securing funding was a major milestone for this initiative. Minister Pathirana successfully obtained approval for a $40 billion loan from the Asian Development Bank. With the funding in place, the foundation stone is scheduled to be laid in September this year, and construction will begin in January 2025.
This project guarantees a consistent and uninterrupted supply of stents and related medications for heart patients. As a result, patients will have timely access to essential medical supplies during their treatment and recovery. By securing these critical resources, the project aims to enhance patient outcomes, minimize treatment delays, and maintain the highest standards of cardiac care.
Upon its fruition, this monumental building will serve as a beacon of hope and healing, symbolizing the unwavering dedication to improving patient outcomes and fostering a healthier society.We anticipate a future marked by significant progress and positive outcomes in Sri Lanka’s cardiovascular treatment landscape within the foreseeable timeframe.

A LOVING TRIBUTE TO JESUIT FR. ALOYSIUS PIERIS ON HIS 90th BIRTHDAY
by Fr. Emmanuel Fernando, OMI
Jesuit Fr. Aloysius Pieris (affectionately called Fr. Aloy) celebrated his 90th birthday on April 9, 2024 and I, as the editor of our Oblate Journal, THE MISSIONARY OBLATE had gone to press by that time. Immediately I decided to publish an article, appreciating the untiring selfless services he continues to offer for inter-Faith dialogue, the renewal of the Catholic Church, his concern for the poor and the suffering Sri Lankan masses and to me, the present writer.
It was in 1988, when I was appointed Director of the Oblate Scholastics at Ampitiya by the then Oblate Provincial Fr. Anselm Silva, that I came to know Fr. Aloy more closely. Knowing well his expertise in matters spiritual, theological, Indological and pastoral, and with the collaborative spirit of my companion-formators, our Oblate Scholastics were sent to Tulana, the Research and Encounter Centre, Kelaniya, of which he is the Founder-Director, for ‘exposure-programmes’ on matters spiritual, biblical, theological and pastoral. Some of these dimensions according to my view and that of my companion-formators, were not available at the National Seminary, Ampitiya.
Ever since that time, our Oblate formators/ accompaniers at the Oblate Scholasticate, Ampitiya , have continued to send our Oblate Scholastics to Tulana Centre for deepening their insights and convictions regarding matters needed to serve the people in today’s context. Fr. Aloy also had tried very enthusiastically with the Oblate team headed by Frs. Oswald Firth and Clement Waidyasekara to begin a Theologate, directed by the Religious Congregations in Sri Lanka, for the contextual formation/ accompaniment of their members. It should very well be a desired goal of the Leaders / Provincials of the Religious Congregations.
Besides being a formator/accompanier at the Oblate Scholasticate, I was entrusted also with the task of editing and publishing our Oblate journal, ‘The Missionary Oblate’. To maintain the quality of the journal I continue to depend on Fr. Aloy for his thought-provoking and stimulating articles on Biblical Spirituality, Biblical Theology and Ecclesiology. I am very grateful to him for his generous assistance. Of late, his writings on renewal of the Church, initiated by Pope St. John XX111 and continued by Pope Francis through the Synodal path, published in our Oblate journal, enable our readers to focus their attention also on the needed renewal in the Catholic Church in Sri Lanka. Fr. Aloy appreciated very much the Synodal path adopted by the Jesuit Pope Francis for the renewal of the Church, rooted very much on prayerful discernment. In my Religious and presbyteral life, Fr.Aloy continues to be my spiritual animator / guide and ongoing formator / acccompanier.
Fr. Aloysius Pieris, BA Hons (Lond), LPh (SHC, India), STL (PFT, Naples), PhD (SLU/VC), ThD (Tilburg), D.Ltt (KU), has been one of the eminent Asian theologians well recognized internationally and one who has lectured and held visiting chairs in many universities both in the West and in the East. Many members of Religious Congregations from Asian countries have benefited from his lectures and guidance in the East Asian Pastoral Institute (EAPI) in Manila, Philippines. He had been a Theologian consulted by the Federation of Asian Bishops’ Conferences for many years. During his professorship at the Gregorian University in Rome, he was called to be a member of a special group of advisers on other religions consulted by Pope Paul VI.
Fr. Aloy is the author of more than 30 books and well over 500 Research Papers. Some of his books and articles have been translated and published in several countries. Among those books, one can find the following: 1) The Genesis of an Asian Theology of Liberation (An Autobiographical Excursus on the Art of Theologising in Asia, 2) An Asian Theology of Liberation, 3) Providential Timeliness of Vatican 11 (a long-overdue halt to a scandalous millennium, 4) Give Vatican 11 a chance, 5) Leadership in the Church, 6) Relishing our faith in working for justice (Themes for study and discussion), 7) A Message meant mainly, not exclusively for Jesuits (Background information necessary for helping Francis renew the Church), 8) Lent in Lanka (Reflections and Resolutions, 9) Love meets wisdom (A Christian Experience of Buddhism, 10) Fire and Water 11) God’s Reign for God’s poor, 12) Our Unhiddden Agenda (How we Jesuits work, pray and form our men). He is also the Editor of two journals, Vagdevi, Journal of Religious Reflection and Dialogue, New Series.
Fr. Aloy has a BA in Pali and Sanskrit from the University of London and a Ph.D in Buddhist Philosophy from the University of Sri Lankan, Vidyodaya Campus. On Nov. 23, 2019, he was awarded the prestigious honorary Doctorate of Literature (D.Litt) by the Chancellor of the University of Kelaniya, the Most Venerable Welamitiyawe Dharmakirthi Sri Kusala Dhamma Thera.
Fr. Aloy continues to be a promoter of Gospel values and virtues. Justice as a constitutive dimension of love and social concern for the downtrodden masses are very much noted in his life and work. He had very much appreciated the commitment of the late Fr. Joseph (Joe) Fernando, the National Director of the Social and Economic Centre (SEDEC) for the poor.
In Sri Lanka, a few religious Congregations – the Good Shepherd Sisters, the Christian Brothers, the Marist Brothers and the Oblates – have invited him to animate their members especially during their Provincial Congresses, Chapters and International Conferences. The mainline Christian Churches also have sought his advice and followed his seminars. I, for one, regret very much, that the Sri Lankan authorities of the Catholic Church –today’s Hierarchy—- have not sought Fr.
Aloy’s expertise for the renewal of the Catholic Church in Sri Lanka and thus have not benefited from the immense store of wisdom and insight that he can offer to our local Church while the Sri Lankan bishops who governed the Catholic church in the immediate aftermath of the Second Vatican Council (Edmund Fernando OMI, Anthony de Saram, Leo Nanayakkara OSB, Frank Marcus Fernando, Paul Perera,) visited him and consulted him on many matters. Among the Tamil Bishops, Bishop Rayappu Joseph was keeping close contact with him and Bishop J. Deogupillai hosted him and his team visiting him after the horrible Black July massacre of Tamils.

A fairy tale, success or debacle
Sri Lanka-Singapore Free Trade Agreement
By Gomi Senadhira
senadhiragomi@gmail.com
“You might tell fairy tales, but the progress of a country cannot be achieved through such narratives. A country cannot be developed by making false promises. The country moved backward because of the electoral promises made by political parties throughout time. We have witnessed that the ultimate result of this is the country becoming bankrupt. Unfortunately, many segments of the population have not come to realize this yet.” – President Ranil Wickremesinghe, 2024 Budget speech
Any Sri Lankan would agree with the above words of President Wickremesinghe on the false promises our politicians and officials make and the fairy tales they narrate which bankrupted this country. So, to understand this, let’s look at one such fairy tale with lots of false promises; Ranil Wickremesinghe’s greatest achievement in the area of international trade and investment promotion during the Yahapalana period, Sri Lanka-Singapore Free Trade Agreement (SLSFTA).
It is appropriate and timely to do it now as Finance Minister Wickremesinghe has just presented to parliament a bill on the National Policy on Economic Transformation which includes the establishment of an Office for International Trade and the Sri Lanka Institute of Economics and International Trade.
Was SLSFTA a “Cleverly negotiated Free Trade Agreement” as stated by the (former) Minister of Development Strategies and International Trade Malik Samarawickrama during the Parliamentary Debate on the SLSFTA in July 2018, or a colossal blunder covered up with lies, false promises, and fairy tales? After SLSFTA was signed there were a number of fairy tales published on this agreement by the Ministry of Development Strategies and International, Institute of Policy Studies, and others.
However, for this article, I would like to limit my comments to the speech by Minister Samarawickrama during the Parliamentary Debate, and the two most important areas in the agreement which were covered up with lies, fairy tales, and false promises, namely: revenue loss for Sri Lanka and Investment from Singapore. On the other important area, “Waste products dumping” I do not want to comment here as I have written extensively on the issue.
1. The revenue loss
During the Parliamentary Debate in July 2018, Minister Samarawickrama stated “…. let me reiterate that this FTA with Singapore has been very cleverly negotiated by us…. The liberalisation programme under this FTA has been carefully designed to have the least impact on domestic industry and revenue collection. We have included all revenue sensitive items in the negative list of items which will not be subject to removal of tariff. Therefore, 97.8% revenue from Customs duty is protected. Our tariff liberalisation will take place over a period of 12-15 years! In fact, the revenue earned through tariffs on goods imported from Singapore last year was Rs. 35 billion.
The revenue loss for over the next 15 years due to the FTA is only Rs. 733 million– which when annualised, on average, is just Rs. 51 million. That is just 0.14% per year! So anyone who claims the Singapore FTA causes revenue loss to the Government cannot do basic arithmetic! Mr. Speaker, in conclusion, I call on my fellow members of this House – don’t mislead the public with baseless criticism that is not grounded in facts. Don’t look at petty politics and use these issues for your own political survival.”
I was surprised to read the minister’s speech because an article published in January 2018 in “The Straits Times“, based on information released by the Singaporean Negotiators stated, “…. With the FTA, tariff savings for Singapore exports are estimated to hit $10 million annually“.
As the annual tariff savings (that is the revenue loss for Sri Lanka) calculated by the Singaporean Negotiators, Singaporean $ 10 million (Sri Lankan rupees 1,200 million in 2018) was way above the rupees’ 733 million revenue loss for 15 years estimated by the Sri Lankan negotiators, it was clear to any observer that one of the parties to the agreement had not done the basic arithmetic!
Six years later, according to a report published by “The Morning” newspaper, speaking at the Committee on Public Finance (COPF) on 7th May 2024, Mr Samarawickrama’s chief trade negotiator K.J. Weerasinghehad had admitted “…. that forecasted revenue loss for the Government of Sri Lanka through the Singapore FTA is Rs. 450 million in 2023 and Rs. 1.3 billion in 2024.”
If these numbers are correct, as tariff liberalisation under the SLSFTA has just started, we will pass Rs 2 billion very soon. Then, the question is how Sri Lanka’s trade negotiators made such a colossal blunder. Didn’t they do their basic arithmetic? If they didn’t know how to do basic arithmetic they should have at least done their basic readings. For example, the headline of the article published in The Straits Times in January 2018 was “Singapore, Sri Lanka sign FTA, annual savings of $10m expected”.
Anyway, as Sri Lanka’s chief negotiator reiterated at the COPF meeting that “…. since 99% of the tariffs in Singapore have zero rates of duty, Sri Lanka has agreed on 80% tariff liberalisation over a period of 15 years while expecting Singapore investments to address the imbalance in trade,” let’s turn towards investment.
Investment from Singapore
In July 2018, speaking during the Parliamentary Debate on the FTA this is what Minister Malik Samarawickrama stated on investment from Singapore, “Already, thanks to this FTA, in just the past two-and-a-half months since the agreement came into effect we have received a proposal from Singapore for investment amounting to $ 14.8 billion in an oil refinery for export of petroleum products. In addition, we have proposals for a steel manufacturing plant for exports ($ 1 billion investment), flour milling plant ($ 50 million), sugar refinery ($ 200 million). This adds up to more than $ 16.05 billion in the pipeline on these projects alone.
And all of these projects will create thousands of more jobs for our people. In principle approval has already been granted by the BOI and the investors are awaiting the release of land the environmental approvals to commence the project.
I request the Opposition and those with vested interests to change their narrow-minded thinking and join us to develop our country. We must always look at what is best for the whole community, not just the few who may oppose. We owe it to our people to courageously take decisions that will change their lives for the better.”
According to the media report I quoted earlier, speaking at the Committee on Public Finance (COPF) Chief Negotiator Weerasinghe has admitted that Sri Lanka was not happy with overall Singapore investments that have come in the past few years in return for the trade liberalisation under the Singapore-Sri Lanka Free Trade Agreement. He has added that between 2021 and 2023 the total investment from Singapore had been around $162 million!
What happened to those projects worth $16 billion negotiated, thanks to the SLSFTA, in just the two-and-a-half months after the agreement came into effect and approved by the BOI? I do not know about the steel manufacturing plant for exports ($ 1 billion investment), flour milling plant ($ 50 million) and sugar refinery ($ 200 million).
However, story of the multibillion-dollar investment in the Petroleum Refinery unfolded in a manner that would qualify it as the best fairy tale with false promises presented by our politicians and the officials, prior to 2019 elections.
Though many Sri Lankans got to know, through the media which repeatedly highlighted a plethora of issues surrounding the project and the questionable credentials of the Singaporean investor, the construction work on the Mirrijiwela Oil Refinery along with the cement factory began on the24th of March 2019 with a bang and Minister Ranil Wickremesinghe and his ministers along with the foreign and local dignitaries laid the foundation stones.
That was few months before the 2019 Presidential elections. Inaugurating the construction work Prime Minister Ranil Wickremesinghe said the projects will create thousands of job opportunities in the area and surrounding districts.
The oil refinery, which was to be built over 200 acres of land, with the capacity to refine 200,000 barrels of crude oil per day, was to generate US$7 billion of exports and create 1,500 direct and 3,000 indirect jobs. The construction of the refinery was to be completed in 44 months. Four years later, in August 2023 the Cabinet of Ministers approved the proposal presented by President Ranil Wickremesinghe to cancel the agreement with the investors of the refinery as the project has not been implemented! Can they explain to the country how much money was wasted to produce that fairy tale?
It is obvious that the President, ministers, and officials had made huge blunders and had deliberately misled the public and the parliament on the revenue loss and potential investment from SLSFTA with fairy tales and false promises.
As the president himself said, a country cannot be developed by making false promises or with fairy tales and these false promises and fairy tales had bankrupted the country. “Unfortunately, many segments of the population have not come to realize this yet”.
