M4.0 Earthquake 13 km WNW of Naisano Dua, Indonesia — March 27, 2024
2024-03-27 18:16:52 UTC (2024-03-27) · approx. 2:16 AM UTC+8 local
On March 27, 2024 at 18:16 UTC, a magnitude 4.0 intermediate depth earthquake struck 13 km WNW of Naisano Dua, Indonesia, at a depth of 71.9 km and coordinates -9.5395°, 123.6659°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 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 12 days ago 27 km N of Kupang, Indonesia. 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 4.0 earthquake near Naisano Dua, Indonesia?
The magnitude 4.0 earthquake that struck 13 km WNW of Naisano Dua, Indonesia on March 27, 2024 at 18:16 UTC had a depth of 71.9 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 4.0 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 4.0 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 27 km N of Kupang, Indonesia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
