Dec 03, Colombo: Chairman of Sri Lanka Geological Survey and Mines Bureau Dr. Wijayananda Herath says that a set of equipment to study the tremors occurring in Ampara district of Eastern Province will be installed by Wednesday.
The equipment acquired and made ready will be transported to Ampara today, he said. The Bureau expects to study the tremors occurring with the new equipment.
Last week several earth tremors were reported from Ampara district. Residents in the area say five tremors occurred within an hour and some houses were also damaged due to the shake-up.
One of the tremors was recorded at the seismic centers as far away as in Anuradhapura, Kandy and Hambantota districts. The Chairman of Sri Lanka Geological Survey and Mines Bureau (GSMB) said that it was a tremor of magnitude 2.3 on the Richter scale.
Sri Lanka is a country which has no historical records on earthquakes. However, lately the country has experienced a spate of more frequent tremors.
According to the data collected so far, scientists believe Sri Lanka is affected by one minor earth tremor in every 1-2 years. However this year the country had experienced three tremors in a short span of time.
A minor tremor in April this year due to an undersea earthquake near the Sumatra region was followed by an aftershock. The tremor was felt by almost all parts of the island.
In May, a minor tremor measuring 3.6 on the Richter scale originated within the country and it was felt in districts of Colombo, Badulla, and Nuwara Eliya in central hills and Ampara in the East. A third tremor originated within the country in the same month was felt in almost the entire country.
Experts at the GSMB believe the island is getting increasingly vulnerable to earthquakes and the need has risen to study the patterns of tremors to prepare for a disaster.
