On July 8, 2025 at 23:50 UTC, a magnitude 5.1 intermediate depth earthquake struck 107 km SSW of Bandar Lampung, Indonesia, at a depth of 79.8 km and coordinates -6.2841°, 104.7897°. The earthquake was reported felt by 7 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.3 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 122 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 403, placing it among routine seismic activity. The nearest populated place is Paojan (population 0).

Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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 5.3 mainshock that occurred 17 days ago 87 km WSW of Labuan, 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.

The epicenter is located in Indonesia, a region characterized by the convergence of the Indo-Australian, Eurasian, and Philippine Sea plates, forming the Sunda-Banda arc system. The nearest mapped fault system is the Sunda megathrust. View all earthquakes in Indonesia.

Common Questions

How strong was the magnitude 5.1 earthquake near Bandar Lampung, Indonesia?

The magnitude 5.1 earthquake that struck 107 km SSW of Bandar Lampung, Indonesia on July 8, 2025 at 23:50 UTC had a depth of 79.8 km. It was felt by 7 people with maximum shaking intensity of MMI 4.3 (moderate). For context, this was a moderate earthquake that could be widely felt.

Where did the earthquake occur?

The earthquake epicenter was located at -6.2841°, 104.7897°, which is 107 km SSW of Bandar Lampung, Indonesia. The nearest populated place is Paojan (population 0). View all earthquakes in Indonesia.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.1 earthquakes can continue for days to weeks and gradually diminish over time.

Is this the same earthquake as the M5.3 one earlier?

No. This magnitude 5.1 earthquake is an aftershock of the larger magnitude 5.3 mainshock that occurred earlier 87 km WSW of Labuan, Indonesia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

Has Indonesia had earthquakes this big before?

The largest recorded earthquake in Indonesia was the M9.1 Indian Ocean earthquake of December 26, 2004. Today's magnitude 5.1 event is significantly smaller than that historical record.
