Andaman Sea Earthquake Prompts Regional Alert, Malaysia Confirms No Tsunami

A significant earthquake struck the Andaman Sea on Sunday, November 9th. The tremor sparked immediate tsunami concerns across coastal regions. Authorities in Malaysia quickly moved to reassure the public.

Malaysia’s meteorological department confirmed there was no tsunami threat to its coastline. The event highlighted the seismic volatility of the region.

Earthquake Details and Conflicting Magnitude Readings

The National Center for Seismology reported a magnitude 5.4 quake. It occurred at 12:06 pm IST at a depth of 90 kilometers. The epicenter was located in the Andaman Sea.

Other agencies recorded slightly different figures. The United States Geological Survey measured it at 5.5. The German Research Centre for Geosciences reported a magnitude of 6.07. This variation is common among different global monitoring systems.

Shallow Quake in a Seismically Active Zone

This was classified as a shallow earthquake. Such events are closer to the Earth’s surface. They often cause stronger ground shaking and potential damage.

The Andaman and Nicobar Islands are in a highly active seismic zone. According to Reuters, the area is classified as Zone V. This indicates the highest risk level for earthquakes.

Tremors were felt across the Andaman and Nicobar Islands. No casualties or major damage have been reported. The quick assessment by Malaysian authorities prevented panic.

The swift analysis by meteorological agencies provided crucial public reassurance. The Andaman Sea earthquake serves as a reminder of the region’s dynamic geology. Constant monitoring remains essential for coastal safety.

What was the magnitude of the Andaman Sea earthquake?

The National Center for Seismology reported a magnitude of 5.4. Other international agencies provided slightly different readings, which is a common occurrence in global seismology.

Was there a tsunami warning after the quake?

Malaysia’s meteorological department explicitly stated there was no tsunami threat. No tsunami warnings were issued for other coastlines following the event.

Why are there different magnitude readings from various agencies?

Different agencies use slightly different methodologies and data processing. This often leads to small variations in the initial reported magnitude of an earthquake.

How deep was the earthquake?

The quake occurred at a depth of 90 kilometers according to Indian authorities. This classifies it as a shallow earthquake, which can be felt more strongly at the surface.

Is the Andaman region prone to earthquakes?

Yes, the Andaman and Nicobar Islands lie in a Zone V seismic area. This is the most active classification for earthquake risk.
