Overview
- A shallow magnitude-6.7 earthquake struck southeast of Palu on Tuesday, June 16, with a hypocenter around 10 km depth, according to BMKG and the USGS.
- Indonesian emergency agencies reported at least two people seriously injured, multiple other casualties with minor wounds, and structural damage to homes and public buildings in parts of central Sulawesi.
- The main quake has produced numerous aftershocks, including a recorded magnitude-5.2 event, and authorities have ruled out a tsunami alert while teams carry out damage assessments.
- Across Peru, the Instituto Geofísico del Perú logged multiple low-to-moderate tremors between June 13–17 — examples include M3.8 near Pozuzo on June 16 and M3.6 near Callao on June 17 — with no significant damage reported.
- Both countries’ agencies are maintaining active monitoring and urging preparedness; the events reflect the Pacific Ring of Fire’s high seismic activity and make aftershock tracking and local inspections the key near-term priorities.
