Panama Records Over 200 Aftershocks Following 7.6-Magnitude Earthquake
Panama was struck by a 7.6-magnitude earthquake on 9 October followed by more than 200 aftershocks, including five of magnitude 6.0 or greater, damaging over 820 homes, as part of earthquakes today that also included smaller events elsewhere.
Panama Earthquake Overview
The mainshock had a revised magnitude of 7.6, with its epicenter 39 km northwest of Tonosí at a depth of 4 km. [2] The Instituto de Geociencias de la Universidad de Panamá revised the magnitude of the 9 October event to 7.6. [2] This main event occurred with an epicenter 39 km northwest of Tonosí at a depth of 4 km according to the same revision. [2] The location placed the earthquake in the Azuero and Veraguas regions of Panama. [2] Reports confirm the depth remained shallow at 4 km for the primary shock. [2]
Aftershock Activity
SINAPROC has reported more than 820 homes damaged and 27 people injured while monitoring continued after the main event. [2] More than 200 aftershocks have been recorded since the 9 October mainshock. [2] Five of those aftershocks reached magnitude 6.0 or greater. [2] The Instituto de Geociencias de la Universidad de Panamá registered the full sequence of more than 200 aftershocks. [2] This aftershock count includes the five events at or above magnitude 6.0. [2] Ongoing seismic activity remained elevated in the days following the initial quake. [2]

Response and Monitoring
The Instituto de Geociencias de la Universidad de Panamá and SINAPROC have continued monitoring and reporting on the sequence. [2] The Instituto de Geociencias de la Universidad de Panamá revised the mainshock magnitude and tracked the aftershocks. [2] SINAPROC issued the situation report that included damage and injury counts. [2] Both agencies provided the official updates as of 11 October 2026. [2]
What to watch next includes continued aftershock monitoring by the Instituto de Geociencias de la Universidad de Panamá and SINAPROC along with any updates on the more than 820 homes damaged.
