M4.8 Earthquake 215 km NNE of Lospalos, Timor Leste — August 26, 2026
2026-08-26 01:48:11 UTC (1 hour ago) · approx. 9:48 AM UTC+8 local
Aftershock of the M5.0 mainshock.
On August 26, 2026 at 01:48 UTC, a magnitude 4.8 shallow crustal earthquake struck 215 km NNE of Lospalos, Timor Leste, at a depth of 11.6 km and coordinates -6.6411°, 127.4930°. This earthquake was detected by 38 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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 5.0 mainshock that occurred 1 day ago 209 km NNE of Lospalos, Timor Leste. Since the mainshock, the USGS has recorded 4 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 4.8 earthquake near Lospalos, Timor Leste?
The magnitude 4.8 earthquake that struck 215 km NNE of Lospalos, Timor Leste on August 26, 2026 at 01:48 UTC had a depth of 11.6 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at -6.6411°, 127.4930°, which is 215 km NNE of Lospalos, Timor Leste.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.8 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.0 one earlier?
No. This magnitude 4.8 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 209 km NNE of Lospalos, Timor Leste. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
