Indonesia's Seismic Activity

Indonesia is recognized as the most seismically active country globally, surpassing Chile and Japan in earthquake frequency ³. The region experiences an average of one magnitude 7 earthquake annually, and a magnitude 8 or greater event approximately every 5 to 7 years ³. A magnitude 9 event is estimated to occur roughly every 100 years somewhere in the country ³.

The country's high seismic activity is due to its location on the Pacific Ring of Fire, where multiple tectonic plates converge and interact. The Indonesian Tsunami Early Warning System (InaTEWS-BMKG) actively monitors seismic events and disseminates information about recent earthquakes ². In the past 365 days, Indonesia has experienced 901 earthquakes, with the recent 7.7 magnitude event being the largest recorded in the past day, week, and month ¹.
