The eruption removed so much magma and rock from below the volcano that the summit collapsed to form a large volcanic depression caldera 1. By continuing to use this website, you agree to their use. It then resurfaces etudy to density changes between magma and rock and so it pushes out through small cracks and explod es out through the volcano.
After the eruption, a lake was formed in the crated 2. The United States Geological Service helped to predict the disaster.

Pinatubo is a volcano located on the island of Luzon in the Philippines, located along the plate boundary between the Eurasian and Philippine Plates. Resettlement camps were used to care for the people displaced.
But if the mountain did blow today, monitoring it would be slightly easier, thanks to 20 years of technological advances. It is thought that the volcano lies slightly offset from the plate boundary, as, when the oceanic plate is subducted it is melted and forced away as molten magma by the high pressures exerted on it.
Aroundother people from the low lying areas who were evacuated returned home afterwards, but it is clear that Lahaars are proving problematic, by burying towns and buildings.

Only a few hundred people died in the initial eruption. Number of eruptions in 20 th Century: Had the typhoon not been stucy, the death toll would have been lower. It is one of the biggest volcanoes in the Philippines and was about ten times larger than the eruption of Mount St.
During andthe Ozone hole over Antarctica reached an unprecedented size. Fine ash fell as far away as the Indian Ocean, and satellites tracked the ash cloud around the globe.
This toll could have been a lot higher if it were not for volcano monitoring, proactive evacuation plans, and luck. It is located at the plate boundary between to the Eurasian and Philippine Plate.
