M4.4 Earthquake 36 km N of Malfa, Italy — September 19, 2026
2026-09-19 20:55:31 UTC (2026-09-19) · approx. 9:55 PM UTC+1 local
On September 19, 2026 at 20:55 UTC, a magnitude 4.4 intermediate depth earthquake struck 36 km N of Malfa, Italy, at a depth of 270.2 km and coordinates 38.9023°, 14.7957°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 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 5.2 mainshock that occurred 18 days ago 50 km WNW of Malfa, Italy. Since the mainshock, the USGS has recorded 5 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 4.4 earthquake near Malfa, Italy?
The magnitude 4.4 earthquake that struck 36 km N of Malfa, Italy on September 19, 2026 at 20:55 UTC had a depth of 270.2 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 4.4 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 4.4 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 50 km WNW of Malfa, Italy. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
