Thailand Earthquake Alert - No Tsunami warning issued

[george]

ASEAN NOW are getting reports of series of earthquakes near Thailand (Near Nicobar Islands).

 

We just got this info, so haven’t had time to check if this is serious or not. No Tsunami warning has been issued.

 

This may be a developing story. https://www.lokmattimes.com/national/46-magnitude-earthquake-hits-nicobar-island/

who knows how many of the tsunami warning buoys are currently operational ?

[george]

Right now, we are seeing moderate earthquakes from 3-5s in the area. We are watching it close because this island can cause a very disastrous earthquake and tsunami.

 

The Andaman–Nicobar region is extremely prone to natural disasters such as earthquakes because of its geological location. The region located in the Himalayan collision zone is in the highest seismic-hazard zone (category V).

 

On 26 December 2004, at 07:58:53 local time (UTC+7), a major earthquake with a magnitude of 9.1–9.3 magnitude struck with an epicentre off the west coast of northern Sumatra, Indonesia. On the other hand, Tthe 1941 Andaman Islands earthquake struck the Andaman Islands on June 26 with a magnitude of 7.7 to 8.1.

 

The Nicobar Islands lie in the Indian Ocean about 800 miles (1,300 km) east of Sri Lanka and have an area of 711 square miles (1,841 square km). The Nicobars, along with the Andaman Islands to the north, constitute the boundary between the southeastern Bay of Bengal (west) and the Andaman Sea (east). The Nicobar group includes the islands of Car Nicobar (north), Camorta (Kamorta) and Nancowry (central group), and Great Nicobar (south).

The tsunami buoy operated by Thailand in that region seems to be operational:

Changes in the water column heights seem to be well within regular levels, if we are to trust the systems placed after 2004 events.

Haven't felt anything in Phuket. Glad that also no danger of tsunami. Not so worried for quotes under 6 that are couple hundred kilometers away. Keep in mind richter scale is exponential and not linear.

 

@georgethe screenshot of yours says "Depth 90.7 miles", that surely can't be right?

Sure hope the wife does not read about this story - I'm telling her it me making the earth move for her

So how do we work out the lottery numbers 46 ,11 ? Bet that's what many Thais will focus on here ????

Quite, they do seem to have had a somewhat checkered history concerning their up-keep.

Never mind the safety of the population along the coastline, just think about the financial aid pouring in from overseas.

Lady buoys are always operational though ????

That’s because a mag 4.6 is only about 1/500,000th the energy released from the 9.2, 2004 earthquake.

I hope the tsunami doesn’t make things worse,I’m already unsteady negotiating some slippery mossy steps on the beach! ????

Ive not experienced an earthquake in phuket since 2012 when we had to run for the hills after a tsunami warning in the afternoon, but allowed to go down after 8pm after the water went well out but only came back slowly. I was meant to fly out that evening but the airport was  closed. Until late at night.. the earthquake came from sumatra but we could feel everything shake, exciting but worrying seeing everybody flee to the hills.

Eh yes, logarithmic scale! Values go up exponentially. There's a special place in hell for people who spandardize non-linear scales for general public use.
