ECONOMYNEXT – Sri Lanka will observe two minutes’ silence on December 26 to remember the victims of the December 26 tsunami of 2004.
The two minutes’ silence would be held from 9.25 to 9.27 am, the state information office said.
The December 26 tsunami caught Sri Lanka unprepared.
It devastated the country’s Eastern Coast a part of which was then under the control of Tamil Tiger separatists.
“During the 2004 Sumatra-Andaman earthquake, the seafloor on the overriding Burma plate deformed vertically, uplifting seaward toward the trench and downdropping (subsiding) landward toward the coastline,” the US Geophysical Survey said in a later analysis.
“Vertical displacement of the water column approximates that of the seafloor below, resulting in the initial
“N-shaped” tsunami wave that is typically generated by subduction earthquakes.
“This N-wave then splits in two, resulting in a pair of N-waves traveling in opposite directions.
“One, the distant tsunami, propagates outbound across the Bay of Bengal towards India and Sri Lanka, eventually reaching the Atlantic and Pacific Oceans. The other, the local tsunami, travelled towards Indonesia, Thailand, and nearby islands in less than an hour.
The tsunami killed close to 35,000 persons and another 5,000 were missing Sri Lanka’s Disaster Management Centre said. Over half a million persons from 235,145 families were affected as the tsunami hit 14 coastal districts.
It is estimated that more than 30,000 persons died.
Over 160,000 are estimated to have perished in Indonesia
Shockwaves from the earthquake off the coast of Indonesia struck Sri Lanka more than two hours after the event.
