A series of earthquakes struck Panama overnight into Saturday (Oct 9-10), including a major M7.7 event near Pitaloza Arriba, an M6.6 quake west of Río Grande, an M5.8 quake near El Cacao, and several smaller M4.5-5.1 aftershocks recorded by GDACS, each potentially affecting hundreds of thousands of people within 100km. The cluster represents one of the more significant seismic events of the day given the large magnitude of the main shock and the dense population potentially exposed, though no casualty or damage figures were reported in the available alerts.
