M4.6 Earthquake 20 km NNW of Pucallpa, Peru — June 30, 2024
2024-06-30 20:47:39 UTC (2024-06-30) · approx. 3:47 PM UTC-5 local
Felt by 1 person across nearby locations. Aftershock of the M5.6 mainshock.
On June 30, 2024 at 20:47 UTC, a magnitude 4.6 intermediate depth earthquake struck 20 km NNW of Pucallpa, Peru, at a depth of 129.1 km and coordinates -8.2077°, -74.6314°. This earthquake was detected by 47 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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 5.6 mainshock that occurred 12 days ago 13 km ENE of San Fernando, Peru. 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 Peru, a region characterized by the northern Peru-Chile subduction zone, complicated by the subduction of the Nazca Ridge. The nearest mapped fault system is the Peru-Chile Trench. View all earthquakes in Peru.

Common Questions
How strong was the magnitude 4.6 earthquake near Pucallpa, Peru?
The magnitude 4.6 earthquake that struck 20 km NNW of Pucallpa, Peru on June 30, 2024 at 20:47 UTC had a depth of 129.1 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at -8.2077°, -74.6314°, which is 20 km NNW of Pucallpa, Peru. View all earthquakes in Peru.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.6 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.6 one earlier?
No. This magnitude 4.6 earthquake is an aftershock of the larger magnitude 5.6 mainshock that occurred earlier 13 km ENE of San Fernando, Peru. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
Has Peru had earthquakes this big before?
The largest recorded earthquake in Peru was the M8.0 Arequipa earthquake of June 23, 2001. Today's magnitude 4.6 event is significantly smaller than that historical record.
