Pre-History

Event	Date	Cause
Quaternary extinction event	Pleistocene 640,000, 74,000, and 13,000 years ago	Clovis comet? (13,000 years ago)[1]
Pliocene–Pleistocene boundary marine extinction	Pliocene 2 Ma	Supernova in the Scorpius-Centaurus OB association

Historical Era

Event	Date	Cause
Meteorite impact (Tablas Island,Romblon)	March 7, 2011	At about 10am on March 7, 2011 (UTC+8), a loud explosion was heard at the island of Tablas in Romblon province in Central Philippines. It was followed by a tremor. Fishermen on sea saw a fiery and swift ball of fire falling from sky (daytime).

Volcanic Eruptions

Pre-History

The Ancestral Mount Pinatubo Erupted during pre-history, but it is less-explosive than the modern Mount Pinatubo.

The Mt.Masaraga,The thick lava flows from Holocene period are still present on the flanks of the mountain.

·         Most of the Eruption recorded from potentially active Stratovolcano according to dated Lava flows .

Event	Date	Notes
Eruption of Mount Panay	Pleistocene	Last eruptive activity is thought to be Pleistocene, about 500,000 years ago.[4]
Eruption of Mount Arayat	Holocene	There are no cultural records of historical eruptions. However, weak steaming is currently present in some of the heavily eroded vents on the North Western side of the summit. The ancient eruptions were said to have caused the formation of a Lava Dome on the Western Slopes of the mountain known as White Rock which makes a nice tourist destination and is usually a field trip destination for students of Pampanga Agricultural College. The Arayat amphitheatre is said to have been caused by the summit's collapse on the western side but a much deeper crater is present on the eastern side, it was said that the mountain was once a volcanic island, until eruptions covered the surrounding area with soil, eruptions were said to be the possible cause of a theorized re-route of Pampanga River which is said to have once passed on the western side rather than eastern side where it currently moves[4]
Eruption of Mount Natib	PleistoceneorHolocene	There are no historical eruptions within the Natib caldera complex. Studies in 1991 (Panum and Rayem) indicate that the last eruptive activity was probably Holocene to upper Pleistocene. An earlier study in 1971 (Ebasco Services) dated the eruptive products between 69,000 +/- 27,000 years old.
Eruption of Mt.Masaraga	Holocene	There are no historical eruptions from the volcano with the last eruptive activity dated as Holocene as reported by the Global Volcanism Program. Thick lava flows from that period are present on the flanks of Mount Masaraga, an understudied volcano in the Philippines.
Eruption of Laguna Caldera	C28,000 BP	The caldera, whose lake surface is only 1m above sea level, may have formed by least two major eruptions of about 1 million and 27,000-29,000 years ago.[4]
Eruption of Mount Malinao	60,000 BP	There are no historical eruptions from Malinao which is believed to have been active from about 500,000 years ago until 60,000 years ago.[5]
Eruption of Cuernos de Negros	12,000 BC	An earlier study in 1971 (Ebasco Services) dated the eruptive products between 69,000 +/- 27,000 years old.
Eruption of Ancestral Pinatubo	Holocene 1.1 million years ago	The activity of Ancestral Pinatubo seems to have begun about 1.1 million years ago and probably ended tens of thousands or more before the birth of 'Modern Pinatubo'. Much of the rugged land surrounding the present volcano consists of remnants of 'ancestral' Pinatubo. It was an andesite and dacite stratovolcano with its eruptive activity much less explosive than modern Pinatubo.
Eruption of Mt.Mariveles	2050 BCE	There are no recorded historical eruptions from Mariveles caldera, with the last activity indicated byRadiocarbon dating occurring around mid-Holocene or about 2050 BCE.
