UPDATE

An official from Indonesia's meteorology agency told Reuters there had been reports of panic in Mataram, the capital of Lombok, where a strong tremor was felt.

"We haven't got any reports of damage or injuries. Communications are not cut," said Hardiatno from Indonesia's meteorology agency.

Indonesia is situated in an area of intense seismic activity known as the "Pacific Ring of Fire".

An earthquake of magnitude 7.6 struck off West Sumatra in Indonesia on Sept. 30 and killed hundreds of people and caused massive property damage.

Hello there,
Yeah Indonesia is extremely active these days. There is so much going on in that region it makes me wonder if Toba is stirring too. I would absolutely love to go to Indonesia to study this region after I graduate. Compared to the rest of the world Indonesia is bumpin both volcanically and seismically absolutely a virtual wonderland to a geologist like me.

If Toba were to activate it would be 100's of times worse than the Megathrust that caused the tsunami, it could kill millions across the globe. So I wonder if anybody is monitoring that beast for activity. It would only be logical to find something going on there with all of the activity within the Sumatran/Indonesian region going on.

Nice find looks like a deep enough quake it could be magma movement or subduction movements or both.
