The Philippine Institute of Volcanology and Seismology (Phivolcs) reports continuing aftershock activity following a magnitude 7.8 earthquake that struck off the coast of Maasim, Sarangani in Mindanao. Across successive updates, Phivolcs counts aftershocks in the thousands as monitoring continues. Reported totals include 989 aftershocks as of early Tuesday (June 9), 2,023 aftershocks as of 7 a.m. on Wednesday (June 10), and 3,860 aftershocks as of 9 a.m. on Friday (June 13, based on the provided articles’ dates). Later reporting on June 11 shows 3,019 aftershocks recorded as of 11 a.m. Phivolcs also notes that aftershocks generally decline over time, with fewer events recorded each day after the initial period. Magnitudes of the aftershocks range from about 1.2–1.3 up to around 6.4–6.7 in different updates. In these reports, Phivolcs specifies that a portion of aftershocks are plotted by instruments and that some are felt by residents in affected areas, with felt counts reported as dozens (for example, 61 felt in one update, and 90 felt in another). Authorities continue response efforts as aftershocks persist.
