M4.8 Earthquake 164 km SE of Lata, Solomon Islands — October 7, 2020
2020-10-07 00:35:53 UTC (2020-10-07) · approx. 11:35 AM UTC+11 local
Aftershock of the M5.1 mainshock.
On October 7, 2020 at 00:35 UTC, a magnitude 4.8 intermediate depth earthquake struck 164 km SE of Lata, Solomon Islands, at a depth of 138.8 km and coordinates -11.9101°, 166.7095°.
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 5.1 mainshock that occurred 5 days ago 176 km SE of Lata, Solomon Islands. 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 4.8 earthquake near Lata, Solomon Islands?
The magnitude 4.8 earthquake that struck 164 km SE of Lata, Solomon Islands on October 7, 2020 at 00:35 UTC had a depth of 138.8 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at -11.9101°, 166.7095°, which is 164 km SE of Lata, Solomon Islands.
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 M5.1 one earlier?
No. This magnitude 4.8 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 176 km SE of Lata, Solomon Islands. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
