Responses to the event international and domestic — Immediate and long term. Plymouth The capital city and most of the infrastructure is located in the south of the island. A risk map was created and is continually updated. Between and Montserrat was devastated by pyroclastic flows. Montserrat is a small island in the Caribbean. Out migration – i n the people of Montserrat were granted full residency rights in the United Kingdom, allowing them to migrate if they chose. The capital, Plymouth, has been covered in layers of ash and mud.

About 4, people who lived there were evacuated by boat. The presence of the volcano resulted in a growth in adventure tourism. The ash cloud was up to 17 kilometers high and was visible on satellite images for hundreds of kilometers over the Atlantic. Volcanic bombs were hurled. Volcanic eruptions and lahars have destroyed large areas of Montserrat. Airports and highways were closed due to the ash dangers, both in Chile and neighbouring countries, eg Argentina.

In the first week of the current eruption, five airplanes encountered eruption-cloud ash, and several sustained significant engine damage. The nature of the hazard type, magnitude, frequency. When the volcano began erupting in Mayit produced high Plinian eruption columns of ash, gas and rock. Out migration – i n the people of Montserrat were granted full residency rights in the United Kingdom, allowing them to migrate if they chose.

However, Chile is vulnerable sstudy earthquake and volcanic events because of its tectonic setting at a subduction zone. It is tectonically active with earthquakes and occasional volcanic eruptions. The airport was buried by Lahars on 11 February S EC Marine life was destroyed because the sea was poisoned by ash.

You might be asked to consider the values and attitudes levek opinions of people involved in the eruption, such as refugees or aid workers for example. S Little infrastructure left untouched in the South to help provide emergency access for people.

This is very low frequency! Volcanic mud flows called lahars blocked roads making local people even more isolated than usual.

EC The seaport and airport lrvel covered in ash causing them to shut down. The volcano had been dormant for over years but started to erupt on the 18 th of July Rivers channels became blocked too causing flooding. In May the volcano erupted after being dormant for 9, years. Pevel dome collapsed resulting in 5 million cubic metres of ash and dust pyroclastic flows in several directions enveloping the surrounding area.

At this margin, clearly marked on the map volxano cross section opposite, there is oceanic to continental convergence. It started with warning signs of small earthquakes and eruptions of dust and ash. Services in the North gradually expanded. New roads and airport were built. In addition, volcanic ash from the eruption clouds caused ground transportation and health problems in Chile and Argentina.

It has been relatively quiet since New roads and a new airport were built. The most violent and intense eruptions occurred in EN Air traffic in the Caribbean was largely disrupted.

The Chilean Navy had managed to evacuate people initially and emergency measures included the following: 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. Both towns were coated in ash, as were local farms.

Services in the north of the island were expanded. S 19 people died, primarily people who lived near the volcano.
