The June 15–16 climatic phase lasted more than fifteen hours, sent tephra about 35 km (22 mi) into the atmosphere, generated voluminous pyroclastic flows ...
The eruption is believed to have contributed to the accumulation of atmospheric ash, [citation needed] capped by the catastrophic eruption of Mount Tambora in 1815, that led to the Year Without a Summer in 1816. Pinatubo eruption: 1500 to 2021: Reawakened in 1991 producing the 2nd largest eruption in the 20th century.

The 1991 eruption of Mount Pinatubo in the Philippines' Luzon Volcanic Arc was the second-largest volcanic eruption of the 20th century, behind only the 1912 eruption of Novarupta in Alaska. Eruptive activity began on April 2 as a series of phreatic explosions from a fissure that opened on the north side of Mount Pinatubo .
Ash from Mount Pinatubo covers Naval Station Subic Bay. On 15 June 1991, the second largest volcanic eruption of the 20th century occurred when Mount Pinatubo, just 20 miles (32 km) from Subic Bay, exploded with a force eight times greater than the Mount St. Helens eruption. The sun was nearly completely hidden as volcanic ash blotted it out.
The United States Geological Survey also created the Volcano Disaster Assistance Program and the Volcano Crisis Assistance Team, which evacuated roughly 75,000 people from the area around Mount Pinatubo before its 1991 eruption. All Colombian counties, by law, have a territorial plan that includes the identification of natural threats ...
