Document Summary
The eruption was large enough to influence global. The second-largest volcanic eruption of this century, and by far the largest eruption to affect a densely populated area, occurred at mount pinatubo in the philippines on june. The eruption produced high-speed avalanches of hot ash and gas, giant mudflows, and a cloud of volcanic ash hundreds of miles across. The impacts of the eruption continue to this day. It is located on the plate boundary between the eurasian and philippine plate. Philippine is oceanic and eurasian is continental--subduction zone, convergent plate boundary. Made from many layers of hardened ash, lava and other volcanic rock. Ash cloud from this climactic eruption rose 35 kilometers into the air. June 12 (philippine independence day), millions of cubic yards of gas-charged magma reached the surface and exploded in the reawakening volcano"s first spectacular eruption. When even more highly gas charged magma reached pinatubo"s surface on.
