On June 5, a Level 3 alert was issued for two weeks due to the possibility of a major eruption. Damage following the Mount Pinatubo eruption was usually caused by lahars — rain-induced torrents of volcanic debris that killed people and animals and buried homes in the months after the eruption. It is also the largest eruption to affect a densely populated area. There was also long and short term aid organized, particularly from the Red Cross and the United States.

Pinatubo is a volcano located on the island of Luzon in the Philippines, located along the plate boundary between the Eurasian and Philippine Plates. During the caldera lake on Mt Pinatubo rose to dangerous levels and the water changed color in January The eruption removed so much magma and rock from below the volcano that the summit collapsed into the underlying magma chamber to form a large volcanic caldera which filled with water that was over 1.

Aboutpeople who evacuated from the lowlands surrounding Pinatubo before and during the eruptions have returned home but face continuing threats from lahars that have already buried numerous towns and villages. Typhoon Yunya was believed to exacerbate the impacts induced by the volcano.

Back to Main Page. There had previously been no monitoring, no collected data, no geological map and no hazards map. Evacuation camps and Government caes were built for those displaced. Huge avalanches of searing hot ash, gas, and pumice fragments pyroclastic flows roared down the flanks of Mount Pinatubo, filling once-deep valleys with fresh volcanic deposits as much as feet meters thick. A blanket fase volcanic ash sand- and silt-size grains of volcanic minerals and glass and larger pumice lapilli frothy pebbles blanketed the countryside.

After the eruption, a lake was formed in the crated 2.

Additionally, another Mount Pinatubo eruption in August killed 72 people. Pinatubo, scientists recorded a landslide, some local earthquakes and a short lived increase in steam emissions from a pre-existing geothermal area.

Volcanic ash is blown in all directions over hundreds of KMs, smothering fields and buildings. These stations nt earthquakes just 5 miles below Pinatubo, meaning a likely eruption would be dangerous. Although much equipment was successfully protected, buildings on two U.

Thousands of small earthquakes occurred beneath Pinatubo throughout April, May and June in View all posts by Geography Wizard. Apologies for the delay in my first post to this post!

Today, the Internet makes it easier to consult with far-off scientists,and GPS and radar satellites make it possible to measure changes in the ground caused by moving magma. It is one of the biggest volcanoes in the Philippines and was about ten times larger than the eruption of My St.

It is located at the plate boundary between to the Eurasian and Philippine Plate. Click here for full screen version.

The new summit of the volcano was metres lower than what it was before the eruption. This website is designed to help students with their studies or simply to educate the interested reader about Geography.

Case Study 4 – Composite Volcano – Mount Pinatubo

Mount Pinatubo had been dormant for around years. This was a sign that hot magma was pushing up against the surface, stretching and bulging the land above.

A slightly different case study here in the sense that Philippines is a Less developed country, whilst my previous case study post, Iceland, was classed an MEDC.

Watch the Sulphur Dioxide cloud disperse on this movie. Thousands of roofs collapsed under the weight of ash made wet by heavy rains. Commercial aircraft were warned about the hazard of the ash cloud from the June 15 eruption, and most avoided it. Most of them had to wait in resettlement camps for a while until they return home. Therefore, it is good to contrast 2 different countries in terms of the impacts and responses to past events. Despite it being possibly a little dated, it is an incredible case study to carry on through your revision!
