Did you feel an earthquake in South Asia? Click here to tell us!

Did you feel the two earthquakes (M8.6 and M8.2) that occurred off Sumatra in the Subcontinent?

First M8.6 event at 08:38 GMT (14:08 IST/14:38 BDT) and second M8.2 at 10:43 GMT (16:13 IST/16:43 BDT)

Numerous felt reports have come in from India, Sri Lanka, Bangladesh and even Nepal for the first earthquake. Please send in a felt report if you felt either or both the earthquakes in Bangladesh, Bhutan, India, Maldives, Myanmar, Nepal and Sri Lanka using the RED or BLUE links above

 

Service notice: As you might have noticed this page isn't being updated as frequently as over the last ten years. It by no means implies this website is 'dead' but since the start of this year other priorities mean there is little time to spend on the ASC as compared to before. I will try to update this page and others on this website as soon as I can and as often as I can. Until then please keep coming back and do continue to send in Felt Reports. They are really appreciated - Stacey Martin (Webmaster), 13 February 2012.

Definition

The earthquake locations listed on this page are preliminary in nature, might be erroneous and are early estimates obtained from Indian and global seismological networks for recent/latest earthquakes in south Asia i.e. Afghanistan, Bangladesh, Bhutan, India, Maldives, Myanmar (Burma), Nepal, Pakistan and Sri Lanka as well as selected events in the Arabian Sea, the Northern Indian Ocean, off the coast of Sumatra, Indonesia and the provinces of Xizang and Xinjiang in China (see networks). These data can be expected to differ with final estimates available days/weeks later. On an average, the information on this page is updated ONCE every 24-hours and is not a real-time or near-real time listing. Please note that this page automatically refreshes itself every 60-seconds. Please check the Page Status above link if you notice any discrepancies.

NOTE: For the island of Sumatra, the above listing displays reported events occurring north of the Equator and offshore events of M
6.0 occurring south of the Equator.

Date & UTC Time: Both the date and the time are listed in UTC (Coordinated Universal Time).
UTC+0430 = Afghanistan
UTC+0500 = Maldives, Pakistan.
UTC+0530 = India, Sri Lanka.
UTC+0545 = Nepal.
UTC+0600 = Bangladesh, Bhutan.
UTC+0700 = Indonesia (Sumatra only).
 

Magnitude: 'Mag' and 'T' represent the magnitude and the type of magnitude respectively. Mw=Moment Magnitude; Ms=Surface wave Magnitude; Mb=Body wave magnitude; ML=Local or Richter Scale magnitude; Mc=Coda magnitude; Md=Duration magnitude; M?=Unknown magnitude type. In addition 'F' indicates a felt event for which a magnitude is unavailable due to various reasons or a magnitude quoted by local media. All events of magnitude M 5.5 are highlighted in red.

Lat, Long, ASC Location: Latitude and Longitude co-ordinates are for the northern & eastern hemispheres respectively and are received from networks marked in the last column (#). A preliminary location is given by the ASC based on these co-ordinates with reference to the nearest geographic location to the epicentre. For selected events, special event pages or ASCN messages are linked to the above listing. The magnitude, location and depth as well as reporting agency that appear in preliminary ASC-N messages might change when more data is available and this page reflecting the changes.

Depth: Depth is in kilometres (kms). Events with focal depths between 0 - 70 kms are shallow, those between 71 - 300 are intermediate and lastly, those occurring greater than 300 kms are deep.
