M4.9 Earthquake 12 km E of Venilale, Timor Leste — June 18, 2026
2026-06-18 07:26:43 UTC (2 hours ago) · approx. 3:26 PM UTC+8 local
Aftershock of the M5.2 mainshock.
On June 18, 2026 at 07:26 UTC, a magnitude 4.9 shallow crustal earthquake struck 12 km E of Venilale, Timor Leste, at a depth of 21.1 km and coordinates -8.6588°, 126.4891°. This earthquake was detected by 48 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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 5.2 mainshock that occurred 11 days ago 22 km E of Venilale, Timor Leste. Since the mainshock, the USGS has recorded 1 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 4.9 earthquake near Venilale, Timor Leste?
The magnitude 4.9 earthquake that struck 12 km E of Venilale, Timor Leste on June 18, 2026 at 07:26 UTC had a depth of 21.1 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at -8.6588°, 126.4891°, which is 12 km E of Venilale, Timor Leste.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.9 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.2 one earlier?
No. This magnitude 4.9 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 22 km E of Venilale, Timor Leste. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
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.
