Seismic Activity in Peru on September 21
In Peru a magnitude 3.7 tremor hit 10 km north of Mala in Cañete at 01:39 local time with 89 km depth. [3] This was followed by a magnitude 3.4 event 31 km north of Huancabamba in Piura at 16:25 local time with 13 km depth. [3] The Cañete tremor registered intensity II-III according to the report. [3] The Piura tremor also registered intensity II-III according to the report. [3] Peruvian authorities noted that Peru registers seismic movements constantly due to its location in the Pacific Ring of Fire. [3] The first event on the day was recorded by the Centro Sismológico Nacional of the Instituto Geofísico del Perú as IGP/CENSIS/RS 2026-0685. [3] The second event was recorded as IGP/CENSIS/RS 2026-0686. [3] Both events occurred on September 21 with the exact local times and depths listed in the official bulletin.

[4] The first tremor occurred at 7:43 p.m. with magnitude 3.1 and superficial depth in Chaparral, Tolima. [4] The second tremor occurred twelve minutes later at 7:55 p.m. with magnitude 3.0 and superficial depth in the same zone. [4] The Servicio Geológico Colombiano reported that more than 130 earthquakes above magnitude 2.0 had been counted with epicenter in Chaparral up to 3:30 in the afternoon. [4] The pair of events belongs to the seismic activity that drew attention during the day in Chaparral. [4] The Red Sismológica Nacional de Colombia registered both movements. [4] The SGC had previously noted highlighted seismic activity in the municipality since the early hours of September 20. [4] Citizens were reminded they can report felt events through the Sismo Sentido platform. [4]

Humanitarian Impact Mapping in Venezuela
A distribution map produced for Libertador parish covering the period September 5-18 was noted in connection with earthquake-related efforts. [5] The map covers the parish Libertador (VE0101) for the dates from September 5 to September 18. [5] It was produced as part of Venezuela earthquake response documentation by MapAction. [5] The map details who, what, where and when for the specified period in the Libertador area. [5] This provides a record of activities during those two weeks in September. [5]
What to watch next includes continued monitoring by the IGP Centro Sismológico Nacional for new seismic reports in Peru and updates from the Servicio Geológico Colombiano on activity in Chaparral.
