M4.6 Earthquake 117 km NW of Ternate, Indonesia — April 24, 2026
2026-04-24 08:41:38 UTC (3 hours ago)
Aftershock of the M5.1 mainshock.
On April 24, 2026 at 08:41 UTC, a magnitude 4.6 shallow crustal earthquake struck 117 km NW of Ternate, Indonesia, at a depth of 35.0 km and coordinates 1.5616°, 126.6602°. This earthquake was detected by 23 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.1 mainshock that occurred 20 days ago 128 km E of Bitung, Indonesia. Since the mainshock, the USGS has recorded 21 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.6 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.1 one earlier?
No. This magnitude 4.6 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 128 km E of Bitung, Indonesia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
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 4.6 event is significantly smaller than that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
