M5.0 Earthquake 82 km W of Labuan, Indonesia — December 20, 2024
2024-12-20 18:22:39 UTC (2024-12-20) · approx. 1:22 AM UTC+7 local
Felt by 2 people across nearby locations. Aftershock of the M5.3 mainshock.
On December 20, 2024 at 18:22 UTC, a magnitude 5.0 shallow crustal earthquake struck 82 km W of Labuan, Indonesia, at a depth of 55.0 km and coordinates -6.4479°, 105.0901°. This earthquake was detected by 145 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.3 mainshock that occurred 26 days ago 87 km WSW of Labuan, Indonesia. Since the mainshock, the USGS has recorded 0 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.

Common Questions
How strong was the magnitude 5.0 earthquake near Labuan, Indonesia?
The magnitude 5.0 earthquake that struck 82 km W of Labuan, Indonesia on December 20, 2024 at 18:22 UTC had a depth of 55.0 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at -6.4479°, 105.0901°, which is 82 km W of Labuan, Indonesia. View all earthquakes in Indonesia.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.0 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.3 one earlier?
No. This magnitude 5.0 earthquake is an aftershock of the larger magnitude 5.3 mainshock that occurred earlier 87 km WSW of Labuan, 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 5.0 event is significantly smaller than that historical record.
