Mount Pinatubo
Case Study
Causes
-
an earthquake with a 7.3 on the richter scale happened around 100 kilometers from the volcano, which moved the crust beneath Mt Pinatubo.
Effects
Social
The eruptions damaged central Luzon, home to about 3 million people. 20,000 indigenous Aeta highlanders, who had lived on the slopes of the volcano, were displaced. About 200,000 people who evacuated from the area around Pinatubo before and during the eruptions have returned home but face the threat of lahars that have buried so many towns and villages. Those who didn't return home had to migrate to Manila
the authorities of the Philippine government moved over 60,000 people away from their homes.
Aid and rescue efforts
75,000 people evacuated. The US air force helped

-
More than 400 people died during the eruption, 300 of them died of falling roofs whilst another 100 from mudflow. Disease that broke out in evacuation camps and the continuing mud flows in the area caused more deaths, bringing the total death toll up to 847 people.

Economic
-
650,000 people lost there jobs

-
The Farmland was destroyed by the ash and this made the farmlands useless, and many lost there jobs because of it
Environmental
The volcano was so strong that it created a huge crater now known as lake Pinatubo as it filled up with water.
Fast flowing volcanic mudflows (lahars) caused a lot of erosion effecting many things like rivers bridges ect.
Volcanic ash is blown in all directions over very long distances, destroying fields and buildings.
-
20 million tons of sulfur dioxide were injected into the atmosphere in Pinatubo's eruption, and the release of the gas cloud around the world caused global temperatures to drop by 0.5°C
Date and location
-
Location
South East Asia, Philippines, the island of Luzon. It is in the middle of the Eurasian and Philippine plate it is part of the chain of volcanoes known as the Luzon volcanic arc.

The tectonic plates
Mt Pinatubo is created by the Eurasian plate subducting underneath the Philippine Sea Plate. The two plates are responsible for the volcano's formation
