False claims circulating on Instagram, TikTok, and Facebook alleged that the Meteorology, Climatology, and Geophysics Agency (BMKG) issued a megathrust earthquake alert for islands across Indonesia in 2026. These posts included a map of earthquake red zones and imagery associated with the BMKG.
False Alarm: No Earthquake Warning Issued
An investigation by Tempo confirmed that the BMKG did not issue a warning about a major earthquake in 2026. While Indonesia experiences the potential for megathrust earthquakes, current technology—including artificial intelligence systems—cannot accurately predict when these events will occur.
The circulating posts also featured a logo falsely attributed to the BMKG. Analysis revealed the logo differed from the agency’s official design, which includes a blue sky, white clouds, and green stripes representing climatology and geophysics.
Dr. Rahmat Triyono, Acting Director of Earthquakes and Tsunami at BMKG, stated on Thursday, February 26, 2026, that no such warning was issued and that the circulating poster was not an official BMKG product. He emphasized that while the BMKG monitors seismic activity and studies potential sources, precise earthquake prediction remains scientifically impossible.
The BMKG urges the public to access information through its official channels: Instagram, X, its website, and Telegram.
Frequently Asked Questions
Is a megathrust earthquake inevitable in Indonesia?
According to the source, Indonesia is surrounded by thirteen megathrust zones, indicating a potential for strong earthquakes and tsunamis, but the timing of these events cannot be predicted.
What is a megathrust?
A megathrust is an area where the Earth’s tectonic plates converge, potentially causing strong earthquakes. The term combines “mega,” meaning large, and “thrust,” referring to a fault.
How can the public ensure they are receiving accurate information?
The BMKG advises the public to access information only through its official Instagram, X, website, and Telegram channels.
Given the potential for misinformation surrounding natural disasters, how can individuals best prepare themselves and their communities for future events?
