2025-03-13 15:45:42 UTC (2025-03-13) · approx. 12:45 AM UTC+9 local
Aftershock of the M5.1 mainshock.
On March 13, 2025 at 15:45 UTC, a magnitude 5.0 intermediate depth earthquake struck 135 km NE of Lospalos, Timor Leste, at a depth of 176.9 km and coordinates -7.5368°, 127.7226°. This earthquake was detected by 75 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 5.1 mainshock that occurred 12 days ago 164 km NE of Lospalos, Timor Leste. 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.

Common Questions
How strong was the magnitude 5.0 earthquake near Lospalos, Timor Leste?
The magnitude 5.0 earthquake that struck 135 km NE of Lospalos, Timor Leste on March 13, 2025 at 15:45 UTC had a depth of 176.9 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at -7.5368°, 127.7226°, which is 135 km NE of Lospalos, Timor Leste.
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 M5.1 one earlier?
No. This magnitude 5.0 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 164 km NE of Lospalos, Timor Leste. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
