MT PINATUBO CASE STUDY GCSE

Dams were built to control the destructive lahars that followed the eruption, and recovery costs totalled billions of Philippine pesos. The impacts of the eruption continue to this day. Mount Pinatubo had been dormant for around years. Only a few hundred people died in the initial eruption. This volcano has experienced major eruptions approximately , , and years before present B. Remarkable sunrises and sunsets were visible around the globe in the years following the Mount Pinatubo eruption.

Evacuation camps and Government shelters were built for those displaced. Ash spewed higher than it ever had before, and lahars, or mudflows, rushed down the slopes in a clatter of banging boulders. The caldera reduced the peak from meters to meters. 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. 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. Had the typhoon not been present, the death toll would have been lower. This volcano has experienced major eruptions approximately , , and years before present B.

Case Study 4 – Composite Volcano – Mount Pinatubo

Back to Main Page. The Volcano is gcae offset from the plate boundary as, when the Oceanic plate is subducted it is melted and forced away as molten czse by the high pressures exerted on it. Also the volcano ejected 10km 3 of magma. Most of them had to wait in resettlement camps for a while until they return home.

All of these massive impacts caused the team to completely evacuate the Clark Air Base.

The aerosol cloud spread around the earth in two weeks and covered the planet within a year. Tropical Storm Yunya was passing 75 km 47 miles to the northeast of Mount Pinatubo, causing a large amount of rainfall in pnatubo region.

The eruption is believed to have influenced caes events as floods along the Mississippi river and the drought in the Sahel region of Africa. This was a massive relief for the pinatjbo, but this first initial eruption was only the warm up, and the big boy was yet to come. Sulfur dioxide in the atmosphere which came from the volcano mixed with water and oxygen in the stratosphere atmosphere to become sulfuric acid, which in turn triggers ozone depletion.

Electricity went off, water was contaminated, road links were destroyed, and telephone links were cut. It is also the largest eruption to affect a densely populated area. But if the mountain did blow today, monitoring it would be slightly easier, thanks to 20 years of technological advances.

The following year 3, homes were destroyed.

After observation of the surrounding area, the team noticed heavily eroded ash and rock deposits that had extended from the volcano for miles on all sides, which was an indication that previous volcanic eruptions were large, which could mean a similar fate for the eruption brewing in Pinatubo. 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.

An evacuation area 20 kilometers Xtudy the caldera lake on Mt Pinatubo rose to dangerous levels and the water changed color in January In order to prevent further impacts from the eruption, the organisations involved could set up permanent monitoring points or use satellite images to analyse changes in land movement and predict future volcanic eruptions at the site.

Electricity went off, water was cwse, road links were destroyed, and telephone links were cut. Number of eruptions in 20 th Century: Farmland destroyed by falling ash and pumice, unusable for years, the harvest was destroyed andpeople lost their jobs. Alert systems put into place to warn of eruption. What they could have done.
