M7.2 Earthquake 10 km WSW of Atiquipa, Peru — June 28, 2024
2024-06-28 05:36:36 UTC (2024-06-28) · approx. 12:36 AM UTC-5 local
Felt by 115 people across surrounding communities. Maximum shaking intensity MMI 7.7 (severe).
On June 28, 2024 at 05:36 UTC, a magnitude 7.2 shallow crustal earthquake struck 10 km WSW of Atiquipa, Peru, at a depth of 24.0 km and coordinates -15.8277°, -74.4540°. The earthquake was reported felt by 115 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.7 (severe). The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. This earthquake was detected by 105 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 893, making it one of the more significant events of the week. The nearest populated place is Chala (population 0).
Physical scale: An earthquake of magnitude 7.2 releases seismic energy equivalent to roughly 951 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 56 km — a useful intuition for the size of the slip patch on the fault.
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.
