The Philippine Institute of Volcanology and Seismology (Phivolcs) reported that about 100 aftershocks were recorded after a magnitude 6.9 earthquake hit Cebu on Tuesday night, 30 September, at 9:59 p.m.
The first strong ones happened shortly after the main quake: a magnitude 5.0 at 10:24 p.m. and a 5.1 at 10:33 p.m., both near Bogo City.
Another tremor, magnitude 3.8, hit near Tabogon at 10:39 p.m.

In a live video message on her official Facebook account, Cebu provincial governor Pamela Baricuatro advised residents to "stay calm and move to open areas; keep away from walls or structures that may collapse and stay alert for aftershocks."
She said the provincial government was assessing the situation and reaching out to municipal officials.
