Note: Earthquakes within 20 km from and at depths less than 20 km under active volcanoes are reported. The list is not complete because many volcanoes are not monitored and/or seismic data in high resolution is not available publicly.

Volcanoes with recent earthquakes above magnitude 2 or more than 10 quakes are listed below:

Apo volcano (Mindanao): magnitude 5.0 earthquake

A magnitude 5.0 earthquake occurred at the volcano 12 hours ago. The quake, which might be volcanic in origin, was located at a depth of 10.0 km depth at 18 km distance SSW from the volcano.
