Earthquakes off north coast of Sumatra, Indonesia

01 January 2005

Since the Aceh earthquake on December 26 2004, Geoscience Australia has recorded 14 earthquakes with magnitude between 6.0 and 7.0 on the Richter scale.

There has also been one aftershock of magnitude 7.1 on the Richter scale. None of these aftershocks has caused a tsunami.

The most recent large aftershock of magnitude 6.5 occurred off the north coast of Sumatra, Indonesia at 01.25pm this afternoon (05.25pm AEDT).

The earthquake occurred out to sea and was unlikely to cause direct damage in Sumatra or Thailand and is extremely unlikely to have caused a tsunami.
