M5.9 Earthquake 34 km SE of Ransiki, Indonesia — April 9, 2024
2024-04-09 00:02:52 UTC (2024-04-09) · approx. 9:02 AM UTC+9 local
Maximum shaking intensity MMI 5.5 (strong).
On April 9, 2024 at 00:02 UTC, a magnitude 5.9 shallow crustal earthquake struck 34 km SE of Ransiki, Indonesia, at a depth of 6.7 km and coordinates -1.6951°, 134.4237°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 177 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 536, placing it among routine seismic activity. The nearest populated place is Ransiki (population 0).
Physical scale: An earthquake of magnitude 5.9 releases seismic energy equivalent to roughly 11 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 7.1 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Indonesia, a region characterized by the convergence of the Indo-Australian, Eurasian, and Philippine Sea plates, forming the Sunda-Banda arc system. The nearest mapped fault system is the Sunda megathrust. View all earthquakes in Indonesia.

Has Indonesia had earthquakes this big before?
The largest recorded earthquake in Indonesia was the M9.1 Indian Ocean earthquake of December 26, 2004. Today's magnitude 5.9 event is significantly smaller than that historical record.
