M4.6 Earthquake 292 km NE of Lospalos, Timor Leste — October 26, 2020
2020-10-26 04:55:50 UTC (2020-10-26) · approx. 1:55 PM UTC+9 local
Aftershock of the M5.9 mainshock.
On October 26, 2020 at 04:55 UTC, a magnitude 4.6 intermediate depth earthquake struck 292 km NE of Lospalos, Timor Leste, at a depth of 169.4 km and coordinates -6.9653°, 129.1459°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — 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 5.9 mainshock that occurred 25 days ago 254 km ENE 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 4.6 earthquake near Lospalos, Timor Leste?
The magnitude 4.6 earthquake that struck 292 km NE of Lospalos, Timor Leste on October 26, 2020 at 04:55 UTC had a depth of 169.4 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at -6.9653°, 129.1459°, which is 292 km NE of Lospalos, Timor Leste.
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 M5.9 one earlier?
No. This magnitude 4.6 earthquake is an aftershock of the larger magnitude 5.9 mainshock that occurred earlier 254 km ENE of Lospalos, Timor Leste. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
