JAKARTA - Head of the Meteorology, Climatology and Geophysics Agency (BMKG), Professor Dwikorita Karnawati suggested that the building design in Jakarta be resistant to megathrust earthquakes. This is because Jakarta is one of the areas most affected if the disaster occurs.
"Actually, what is worried (from the megathrust earthquake) is cities with soft ground, for example Jakarta," said Dwikorita, who is familiarly called Rita while talking to Eddy Wijaya on the EdShare On podcast which aired on Wednesday, April 23, 2025.
Prof. Rita explained that the city with soft soil triggered very strong earthquake waves. This is because the soft soil structure was unable to reduce earthquake waves, even though the epicenter was hundreds of kilometers from the area. "This condition occurs in several countries such as Mexico. Likewise in Jakarta and Bangkok. In these cities the shocks will strengthen even though the distance is hundreds of kilometers," he said.
Previously, the BMKG warned the public of the potential for a megathrust earthquake in a number of regions in Indonesia, such as in the Sunda Strait which is predicted to have a magnitude of 8.7, and Mentawai-Siberut which has a potential of 8.9 magnitudes. The massive earthquake is predicted to cause a tsunami up to a height of 20 meters. Not to mention the tremors caused by it can destroy buildings that are even hundreds of kilometers from the epicenter.
Prof. Rita compares the soft soil conditions of Jakarta with Sukabumi, especially in the Ratu Port area, which is quite close to the area predicted to be the megathrust earthquake point. According to the Alumni Engineering Geology, Leeds University England, the Ratu Port area has a solid soil texture so that earthquake shocks will not be as big as Jakarta.
"So the earthquake wave propagation if it penetrates a hard or dense object will be damped. Once (the wave) passes through the soft soil, shakes again," said Prof. Rita.
Prof. Rita then asked the Ministry of Public Works and the Provincial Government of Jakarta to carry out strict supervision of the building design in Jakarta. Do not let the tall buildings that have been built do not have the resilience of large-power earthquakes. "There needs to be an inspection to ensure that residential buildings with towers are high, it is certain that they are ready to face strong shocks," he said.

Head of BMKG, Dwikorita Karnawati responded to tidal flooding which is often a big problem in Jakarta today. According to Dwikorita, tidal flooding can be overcome with green environmental or environmental reforestation to support the Giant Sea Wall project or the giant sea wall that continues to be built in Jakarta.
"In our opinion, the right solution is back to green. Maybe combined with giant sea wall, God willing, it will be more effective. Return to green, mangrove, protected forest, that seems very important," said Rita to Eddy Wijaya.
The Yogyakarta-born academic, June 6, 1964, explained that the average sea level increase rate in Indonesia reaches 4.3 millimeters per year. This condition exacerbates the Jakarta area because it is accompanied by subsidence or land subsidence reaching 6 to 7 centimeters per year.
"If (Jakarta) sinks wallahu a'lam, yes. If the land drops, yes," said Prof. Rita in response to Eddy Wijaya's question about Jakarta's prediction of sinking from former American President Joe Biden.
In July 2021, former US President Joe Biden in his speech mentioned the tidal flood that could sink Jakarta. Biden even predicts that Jakarta will sink for the next 10 years or around 2031.

The figure of Eddy Wijaya is a podcaster who was born on August 17, 1972. Through the @EdShareOn YouTube account, Eddy interviewed many national figures ranging from state officials, legal experts, political experts, national politicians, to Indonesian celebrities. The man with the characteristics of the right cheek dimple is also a nationalist who is a struggling activist for discriminated and social observers by helping the community through the Eddy Wijaya Peduli Bangsa foundation.
He is also active in sports by serving as Daily Chair of the Indonesian Horseed Sports Association (Pordasi) Pacu and has also served as Deputy Chairperson of the All-Indonesian Badminton Association (PBSI) East Jakarta. His ideas were formed because of his hard work to be independent from the age of 13 years until his success as he is now. For Eddy, the world of work is not as smooth as imagined, failure and rejection are commonplace. This is what makes him hold on to the tagline "Success is only a matter of time". (ADV)
