Auwe, another great Temblor:
A large (Mw=8.2) earthquake occurred off the western coast of Northern Sumatra today, and tsunami warnings were issued in nearby Thailand.
The quake struck at about 11:10 PM local (11:10 AM EST), and was about one fiftieth as strong as the December 26 event. The hypocentre was about 30 km (+/- 6.1 km) deep, and was followed by a Mw 6.0 aftershock within about 30 minutes, offset to the South-East. It is not known at present whether these events produced tsunamis, but the rapid Moment Tensor Solution for this event shows an almost vertical motion for the event.
Another Indonesian earthquake today...
