Santo Tomas
"Santo Tomas is a stratovolcano with numerous volcanic vents and fissures (Philippines Commission of Volcanology, 1981). There was a report of an eruption or "displacement" in the region on January 4, 1641, described as an outburst of water accompanied by an earthquake. January 4, 1641 is the date of the major eruption of Parker volcano in southern Mindanao that impacted much of the Philippines."  -Smithsonian Volcano Archive
