Additional info:
The earthquake was not felt by people in the Czech Republic and no damage to buildings or infrastructure is expected here.
The tsunami triggered by the earthquake destroyed a great part of the coast of southeast Asia and many islands in the Indian Ocean. The main shock was followed by a great number of aftershocks, dozens of which were also recorded by the IPE. The earthquake was the third largest quake in the last 100 years and the largest since 1964.
