On March 16, 2022 at 23:15 UTC, a magnitude 5.9 shallow crustal earthquake struck 59 km NNW of Bandar-e Lengeh, Iran, at a depth of 22.0 km and coordinates 27.0219°, 54.5843°. The earthquake was reported felt by 64 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.0 (severe). The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. The nearest populated place is Bastak (population 0).

Physical scale: An earthquake of magnitude 5.9 releases seismic energy equivalent to roughly 11 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 7.1 km — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in Iran, a region characterized by the Zagros fold-and-thrust belt, where the Arabian Plate collides with Eurasia at 20-25 mm per year. The nearest mapped fault system is the Zagros Fault. View all earthquakes in Iran.

Common Questions

How strong was the magnitude 5.9 earthquake near Bandar-e Lengeh, Iran?

The magnitude 5.9 earthquake that struck 59 km NNW of Bandar-e Lengeh, Iran on March 16, 2022 at 23:15 UTC had a depth of 22.0 km. It was felt by 64 people with maximum shaking intensity of MMI 7.0 (severe). For context, this was a moderate earthquake that could be widely felt.

Where did the earthquake occur?

The earthquake epicenter was located at 27.0219°, 54.5843°, which is 59 km NNW of Bandar-e Lengeh, Iran. The nearest populated place is Bastak (population 0). View all earthquakes in Iran.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.9 earthquakes can continue for days to weeks and gradually diminish over time.

Has Iran had earthquakes this big before?

The largest recorded earthquake in Iran was the M7.8 Tabas earthquake of September 16, 1978. Today's magnitude 5.9 event is significantly smaller than that historical record.
