Post-Tsunami Earthquakes: Aftershocks or Foreshocks?

 

From what I gather from various sources, including theraw data that is publicly available, it appears that the earth quakes following the event of December 26, 2004, are following an unusal pattern. Following most earthquakes, there are aftershocks. At first they can be quite powerful but over time decrease in strength and the time between them shrinks from minutes, to hours, to months, to years. In the case of the Boxing Day quake, many quakes of 5.0 - 6.0 magnitude have been happening without any sort of quiet erupting from mother earth. Instead, there are fears that these quakes, which are now moving north towards India are raising concerns regarding the possibility of these quakes being foreshocks to a future event. One must wonder. And one must hope for the best.

Quake may hit Assam: US agency

If the sequence of these aftershocks moves further north then it may trigger a very big earthquake in Assam region," said Ramesh P. Singh, vice-chairman of the International Union of Geodesy and Geophysics.

A theory exist that says the recent massive earth quake in northeast of Banda Aceh in Indonesia's Aceh province really has its roots in the series of earthquakes in Assam over the last three years. It seems the Andaman plate line of 700 miles may be collapsing. That will be a much larger catastrophe.

"Fortunately an earthquake as powerful as the Assam event only occurs about once every 3,000 years on the Oldham fault," said Professor Bilham. "They are very rare, but could be extremely devastating in this region, given the huge population now living in Bangladesh and the poor construction practices there.
