There is no confirmation about triggering of tsunami so far. An investigation is underway to determine, if a tsunami has been triggered by this earthquake.

However, based on preliminary earthquake information and numerical modeling, the following is the threat assessment for the Indian mainland and islands:

The list below shows the forecast arrival time (T) of the first wave estimated to exceed 0.2 m amplitude at the beach in each zone, and the amplitude of the maximum beach wave predicted for the zone. Zones where the estimated wave amplitudes are less than 0.2m at the beach are not shown.

The list is grouped by State (alphabetic order) and ordered according to the earliest estimated times of arrival at the beach.

Please be aware that actual wave arrival times may differ from those below, and the initial wave may not be the largest. A tsunami is a series of waves and the time between successive waves can be five minutes to one hour.

The threat is deemed to have passed two hours after the forecast time for last exceedance of the 0.5m threat threshold for a zone. As local conditions can cause a wide variation in tsunami wave action, CANCELLATION of national warnings and ALL CLEAR determination must be made by national/state/local authorities.

For regions under ALERT (Orange), public should be advised to avoid beaches and low-lying coastal areas. Vessels should move into deep ocean

For regions under WATCH (Yellow), no immediate action is required

For regions under NO THREAT (Green), no action is required

This bulletin is being issued as advice. Only national/state/local authorities and disaster management officers have the authority to make decisions regarding the official threat and warning status in their coastal areas and any action to be taken in response.

Additional bulletins will be issued by ITEWC INCOIS for this event as more information becomes available.
