Over the past 30 days, Indonesia has experienced more than 1,400 earthquakes. On November 27, 2025, a significant 6.3 magnitude earthquake hit near Sumatra. Although the fear was palpable, fortunately, no fatalities or severe damage occurred. However, the fear is heightened due to the ongoing floods and landslides.
Indonesia's location on the Pacific Ring of Fire makes it one of the world's most seismic regions. Here, 15 massive tectonic plates collide and shift, causing about 90% of the world's earthquakes. Thousands of minor to significant earthquakes hit Indonesia annually, which is a common phenomenon.

Beneath Sumatra, the Indo-Australian plate is slowly subducting under the Eurasian plate at a rate of 5-7 centimeters per year, creating immense pressure. When this pressure is abruptly released, it results in earthquakes. The Great Sumatra Fault, a significant fracture in the region, is responsible for recent quakes of magnitudes 6.6 and now 6.3.
Back in 2004, a massive 9.1 magnitude quake hit near Sumatra, leading to a tsunami that claimed over 230,000 lives. This recent quake was just 10 kilometers deep, causing intense ground shaking, but fortunately, there was no tsunami threat.

Simultaneously, Cyclone Senyar has caused severe flooding and landslides in Sumatra. Over 25 people have already lost their lives, and 10 are still missing. More than 8,000 people have been evacuated to safety. Roads are destroyed, and villages are submerged in water and debris, exacerbated by frequent aftershocks.
Scientists warn of potential aftershocks, while meteorological agencies caution about impending heavy rains and more flooding. The government is airlifting essential supplies like food and water to those affected, urging citizens to remain vigilant. Annually, countries like Indonesia face earthquakes and floods; however, climate change is intensifying these events, causing heavier rains and stronger tremors.
