M4.1 Earthquake 206 km E of Levuka, Fiji — February 7, 2024
2024-02-07 18:59:05 UTC (2024-02-07) · approx. 6:59 AM UTC-12 local
On February 7, 2024 at 18:59 UTC, a magnitude 4.1 deep-focus earthquake struck 206 km E of Levuka, Fiji, at a depth of 559.5 km and coordinates -17.7296°, -178.7657°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 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 5.0 mainshock that occurred 22 hours ago 215 km ENE of Levuka, Fiji. Since the mainshock, the USGS has recorded 3 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 4.1 earthquake near Levuka, Fiji?
The magnitude 4.1 earthquake that struck 206 km E of Levuka, Fiji on February 7, 2024 at 18:59 UTC had a depth of 559.5 km. For context, this was a light earthquake commonly felt near the epicenter.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.1 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 4.1 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 215 km ENE of Levuka, Fiji. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
