This is the characteristic of a megathrust triggering a tsunami, said Golden Time

Jakarta, Indonesia – The possibility of a megathrust earthquake, capable of unleashing a tsunami with waves towering up to 20 meters, has become a critical concern for Indonesia. Authorities are ramping up efforts to prepare for this potential disaster, emphasizing the need for swift action and community readiness.

When could such a catastrophic event strike? And how much time will coastal communities have to evacuate?

Can a megathrust earthquake truly trigger a massive tsunami?

Wijayanto,Head of the Earthquake and Tsunami Data Working Team at the Meteorology,Climatology,and Geophysics Agency (BMKG),has underscored the gravity of the situation. “The megathrust zone can generate earthquakes as powerful as magnitude 9, which have the potential to cause tsunamis,” he stated in a recent interview on Saturday, January 11, 2025.

He further explained, “If an earthquake exceeding magnitude 8.7 occurs in the Sunda arc megathrust zone—stretching from western Aceh to the Sunda Strait and southern Java to Nusa Tenggara—it could produce a tsunami over 20 meters high along the coast.”

Does every megathrust earthquake result in a tsunami?

Wijayanto clarified that not all megathrust earthquakes cause tsunamis, but those with a magnitude above 7 have the potential to do so.

What is the golden window for evacuation during a tsunami?

“Early warnings are issued within 3 minutes.On average, tsunami waves reach the coast in 20 to 30 minutes, giving communities and local governments a critical window of 15 to 25 minutes for evacuation,” Wijayanto explained.

He stressed the importance of preparedness to minimize casualties, ideally aiming for zero fatalities. “The readiness of communities, along with central and regional governments and the private sector, is crucial. Building self-rescue capabilities and fostering public understanding are paramount,” he added.

Indonesia’s Megathrust Threat: A Looming Seismic Crisis

Nestled along the Pacific Ring of Fire, indonesia is no stranger to seismic activity. However, recent findings by Nuraini Rahma Hanifa, a scientist at the Geological Disaster Research Center of the National Research and Innovation Agency (BRIN), have shed light on a particularly alarming threat: the megathrust segment in southern Java, including the Sunda Strait. According to her research, this region holds the potential to unleash an earthquake with a magnitude between 8.7 and 9.1, capable of triggering devastating tsunamis.

“The potential for this megathrust could trigger a large earthquake and tsunami, which would spread through the Sunda Strait to Jakarta with an arrival time of around 2.5 hours,” said Rahma, as quoted from the official BRIN website on Saturday, February 11, 2025.

Collaborative simulations conducted by BRIN and other research institutions predict that such an earthquake could generate tsunami waves reaching up to 20 meters along Java’s southern coast, 3-15 meters in the Sunda Strait, and approximately 1.8 meters on Jakarta’s northern shores. The accumulating tectonic energy in the subduction zone south of Java poses a significant risk, with a sudden release potentially causing widespread destruction across coastal regions.

Mitigation Strategies: A Two-Pronged Approach

To combat this imminent threat, BRIN recommends a dual strategy combining structural and non-structural measures.Structural solutions include building tsunami barrier embankments,wave breakers,and implementing strategic coastal spatial planning,ensuring a minimum distance of 250 meters from the shoreline.

“The growth of coastal forests or natural vegetation such as pandanus and mangroves is also an ecosystem-based solution to reduce tsunami wave energy,” Rahma stressed.

These natural barriers not only mitigate wave impact but also contribute to environmental sustainability, offering a holistic approach to disaster risk reduction.

BMKG’s Role in Earthquake and Tsunami Preparedness

The Meteorology, Climatology, and Geophysics Agency (BMKG) has taken significant steps to enhance Indonesia’s disaster preparedness. Wijayanto, a BMKG representative, revealed that the agency has installed 550 seismographs nationwide to monitor seismic activity.

“BMKG has installed 550 seismographs throughout indonesia to monitor earthquake activity, the InaTEWS management system in Jakarta and Bali as a backup for preparing tsunami early warnings in less than 3 minutes, and also Tsunami gauge equipment for confirmation/validation of BMKG and BIG cooperation,” explained Wijayanto.

The InaTEWS (Indonesia Tsunami Early Warning System) is a cornerstone of these efforts, designed to deliver critical alerts within three minutes of an earthquake. This rapid response system, combined with collaboration from the Geospatial Details Agency (BIG), ensures a robust framework for disaster mitigation.

Indonesia’s Seismic Vulnerability: A Global Concern

Indonesia’s unique position at the intersection of three major tectonic plates—the Indo-Australian, Pacific, and Eurasian—makes it one of the most seismically active regions globally. the country is home to 13 megathrust segments, each with the potential to generate catastrophic earthquakes.

Daryono, head of the BMKG Earthquake and Tsunami Center, has emphasized the importance of understanding these geological risks. with the constant accumulation of tectonic energy, the need for proactive measures and public awareness has never been more critical.

Conclusion: A Call for Action

Indonesia’s seismic vulnerability underscores the urgent need for comprehensive disaster preparedness. By combining advanced monitoring systems,structural defenses,and ecosystem-based solutions,the nation can mitigate the risks posed by megathrust earthquakes and tsunamis.
