Megathrust Earthquakes: Indonesia Braces for Potentially Catastrophic Events​

• 14 AUGUST 2024

Indonesia’s Meteorology, Climatology, and Geophysical Agency (BMKG) has issued a warning about impending megathrust earthquakes that could lead to massive tsunamis, stressing the urgent need for preparedness.

A megathrust earthquake occurs in the shallow, angled subduction zones where one tectonic plate is forced under another. These zones can produce the most powerful earthquakes and potential tsunamis, especially in highly seismic regions like Indonesia.

Understanding Megathrust Earthquakes:
BMKG highlights the particular danger from the Sunda Strait Megathrust M 8.7 and the Mentawai-Suberut Megathrust M 8.9. These faults have not released significant energy for centuries, accumulating stress that could lead to catastrophic earthquakes and tsunamis.

Historic Inactivity Raises Concern:
The last major releases along these megathrust zones were hundreds of years ago—Sunda Strait in 1699 and 1780 and Mentawai-Siberut in 1797 and 1833. This long inactivity increases the potential for a high-magnitude earthquake.

Indonesia’s Vulnerable Megathrust Zones:
Three key megathrust regions in Indonesia pose a significant threat:
– Sunda Megathrust covering Sumatra, Java, Bali, Lombok, and Sumba.
– Banda Megathrust which includes parts of Maluku and Sulawesi.
– Northern Papua and the Philippine Sea Plate.

Comprehensive List of Threat Zones:
Based on the 2017 Indonesia Earthquake Source and Hazard map, the following are detailed as high-risk megathrust segments:
– Sunda Strait-Banten Segment: Potential magnitude up to 8.8, historical quakes in 1699 and 1780.
– Java Western Segment: Notable for a M 8.1 quake in 1903.
– Central and Eastern Java Segment: Recorded a M 7.8 quake in 1994.
– Bali Segment: The highest potential with a magnitude up to 9.0, no historical quakes recorded.

BMKG’s Mitigation Efforts:

To counter the potential disaster, BMKG has enhanced its monitoring and early warning systems. The Indonesia Tsunami Early Warning System (InaTEWS) plays a crucial role in disseminating rapid alerts, combined with community education and evacuation drills.

The threat of megathrust earthquakes is a pressing concern for Indonesia and its neighbors, including Singapore. Effective mitigation and preparedness strategies are essential to minimize potential damage and ensure rapid response to safeguard populations in these high-risk zones.

BMKG warns of the imminent threat of megathrust earthquakes in Indonesia, capable of generating devastating tsunamis. Historical gaps and the buildup of tectonic stress underline the urgency for regional preparedness and robust early warning systems to mitigate the impact on millions living in vulnerable areas.

There's nothing much we can do now.
Impending event.

Depending on its magnitude and movement direction, we are not only separated from the Sumatran epicenter by mountains, but also by a straits of water. The swaying of buildings in Singapore is to be expected as I had experienced it once myself in my condo in central Singapore during a similar earthquake in Sumatra before.

Furthermore, the soil foundation of central Singapore is mostly of clay and porous materials. Probably a mini tsunami at the west and north west coasts of Singapore can be expected at the worst scenario. However, the western part of Singapore are mostly rock structures and these are more immune to ground movements.

However, earthquakes tend to move and spread as time goes by. So, the same cannot be said in fifty or a hundred years from now.

Many Japanese fled their island due to quake anxiety. Dunno when it will hit. At night cannot sleep.

when toba moves and shakes (god please don’t sexplode) it’s shit hitting the fan in the whole region.

After such devastation, there will be a economic boom on rebuilding like in Gaza.

Forest City in Jb will bear the brunt of it..The buildings there are built on reclaimed land, definitely will not be able to withstand a severe Sumatran earthquake..

boooom and bust for at least 69 years as hot pumice and ash cloud kill every living thing on the surface and cause a 69-week ice cold winter in the tropics.

If this were to happen, I hope the first to go down is mbs so that pap cannot use this to tell lie and also mbs mostly are foreigners.

SG will sink into the sea and become a legend like Atlantis. Many hundred years from now, people will talk about us, tell the legend of how great the country was, the great buildings, the advanced people, the great civilisation that once lived on the island.

Stay in.landed. problem solved.

Of course we are. We're the first to discover, unlock, and apply the power of a packet of tissue paper in repelling table invaders.

add kopi (with sugar), kaya toast and eggs with thick sweet soy sauce for breakfast, iced drink with sweet syrup and more starchy food for lunch, soda and cai png with sweet and sour pork or fish for dinner plus nonya kueh, donut, bread and cake for snacks. sinkies cummitting slow suicide.

Those staying in 60 storey hdb flats will be worried.

That's scary!! You really scared me. Will skip dinner this evening. Just drink water can already.
