PINATUBO, June 15th, 1991 - The Second Powerful Volcanic Eruption of the 20th Century Occurred in the Philippines' Luzon Volcanic Arc \\ Wikipedia.org On June 12, the volcano's first spectacular eruption sent an ash column 19 km into the atmosphere. Additional explosions occurred overnight and the morning of June 13. Seismic activity during this period became intense. When even more highly gas-charged magma reached Pinatubo's surface on June 15, the volcano exploded, sending an ash cloud 40 km into the atmosphere.
The eruption of Mount Pinatubo deposited large amounts of particulate matter into the atmosphere, enough to lower global temperatures by about 0,5°C Пинатубо \\ ru.Wikipedia.org
