LEDC VOLCANO CASE STUDY A LEVEL

The small population of the island 11, people was evacuated in to the north of Montserrat as well as to neighbouring islands and the UK. It’s split into 3 sections: The program will support studies of the history of eruptions at these volcanoes, assessments of volcanic hazards, and the creation of a real-time monitoring network and early warning system. Vulnerability This area of Chile has reasonably low population density, so limits the potential impacts on the local scale. Chile accepted aid and support from other South American countries and the wider world.

During this time, Montserrat was devastated by pyroclastic flows. The ash plume was so thick in some parts of Argentina that schools, highways and airports were forced to close. An emergency jetty was built in the North to allow sea access. As the plate descends it causes earthquakes in the Benioff zone, and volcanoes occur here because of melting of the plate in the asthenosphere. Airports and highways were closed due to the ash dangers, both in Chile and neighbouring countries, eg Argentina.

Beforeit consisted mainly of a rhyolitic lava dome that was last active 9, years ago. Airports in Chile, Argentina and Uruguay, up to 2, km from the volcano, were forced to close or cancel flights.

British citizenship was granted in The island used to be self-sufficient, but became dependent on food aid. Plymouth The capital city and most of the infrastructure is located volcani the south of the island.

About 4, ledx who lived there were evacuated by boat. Evacuations began from South to North, but it was a slow process. Chile only has 20 volcanoes with completed geological studies, 7 which have had hazard assessments and 7 more that are monitored. Production of associated hazards from volcanoes.

Chaiten is a small volcano in western Chile in the Andes fold mountains.

The most violent and intense eruptions occurred in lecel Airports and highways were closed due to the ash dangers, both in Chile and neighbouring countries, eg Argentina.

Services in the north of the island were expanded. This volcano has a history of eruptions but in human terms it is infrequent.

Volcanic bombs were hurled. World Society for the protection of Animals brought food and medicine for animals. By late May the casf eruptions had created a new dome of ,m 2 containing 55million m 3 of material.

The ash cloud was up to 17 kilometers high and was visible on satellite images for hundreds of kilometers over the Atlantic. The major impact was on farming, and many farm animals were killed by suffocating on the ash.
