M5.0 Earthquake 39 km S of Kirakira, Solomon Islands — March 19, 2024
2024-03-19 14:39:08 UTC (2024-03-19) · approx. 1:39 AM UTC+11 local
Aftershock of the M5.1 mainshock.
On March 19, 2024 at 14:39 UTC, a magnitude 5.0 shallow crustal earthquake struck 39 km S of Kirakira, Solomon Islands, at a depth of 61.6 km and coordinates -10.8006°, 161.8513°. This earthquake was detected by 102 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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 22 days ago 14 km NW of Kirakira, Solomon Islands. 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 5.0 earthquake near Kirakira, Solomon Islands?
The magnitude 5.0 earthquake that struck 39 km S of Kirakira, Solomon Islands on March 19, 2024 at 14:39 UTC had a depth of 61.6 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at -10.8006°, 161.8513°, which is 39 km S of Kirakira, Solomon Islands.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.0 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.1 one earlier?
No. This magnitude 5.0 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 14 km NW of Kirakira, Solomon Islands. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
