Magnitude Megathrust earthquake in the Sunda Strait is not just talk. Because it could be mega super powerful and cause a big tsunami.

So according to the Meteorology Climatology and Geophysics Agency ( BMKG ) the Banten earthquake that occurred on January 14 2022 was only a subduction earthquake and one day it will trigger a megathrust earthquake in the Sunda Strait .

The 8.7 magnitude megathrust earthquake in the Sunda Strait was warned last year and has now been reminded by the head of the BMKG .

Indeed, this is just a prediction, but still this prediction must be accompanied by vigilance.BMKG and scientists do not yet have the technology to determine when an earthquake occurs.

So from that, we must increase our vigilance because a big earthquake can happen at any time.On that occasion, Daryono also said that if the strength of the earthquake reaches a magnitude of 8.7, the prediction of a tsunami is high.

This is indeed a natural process that continues at all times and in time will occur.Daryono said that currently it is in a condition hundreds of years after the megathrust earthquake and has not yet occurred.

It’s clear that the cycle can occur after hundreds of years ago.

We have recorded many things, such as the Pangandaran earthquake with a magnitude of 7.7 in 2006 and the Bengkulu earthquake of 8.7, which can be used as references to increase awareness.

The Meteorology, Climatology and Geophysics Agency (BMKG) said there was a potential for an earthquake of 8.7 magnitude (M) in the Sunda Strait, Banten. The BMKG also mentions the characteristics that mark this large earthquake occurring and can trigger a tsunami as high as 19 to 21 meters. So, what are the signs?

“The characteristics of an earthquake that has the potential for a tsunami (we feel dizzy, can’t stand up, stagger and feel nauseous. So those are the characteristics we can feel when an earthquake occurs, which generally has the potential for a tsunami,” said the BMKG Data and Information Coordinator for Class I Geophysics Station Tangerang Urip Setiyono when met in Pandeglang, Banten, Tuesday (18/1/2022).

In addition to this natural sign, another characteristic is that the electricity network and telecommunications lines will die immediately after this earthquake occurs. Urip also advised residents to immediately evacuate to a safer place if a large shock was felt by residents.


Daryono also ensured that BMKG will continue to improve the performance of tsunami early warnings to be faster and more accurate.
