The air pollution generated by the ash caused health problems for people. There were s everal hundred domestic flights in Argentina and Chile and several dozen international flights from Santiago, Chile and Buenos Aires, Argentina cancelled. Smaller communities to the southeast such as Chubut and Rio Negro also received heavy ash falls. It has been relatively quiet since New roads and a new airport were built. S 19 people died, primarily people who lived near the volcano. Chile accepted aid and support from other South American countries and the wider world.
The capital, Plymouth, has been covered in layers of ash and mud. Volcanic bombs were hurled. There is a volcanic area located in the south of the island on Soufriere Hills called Chances Peak. Between and Montserrat was devastated by pyroclastic flows. Many homes and buildings have been destroyed, including the only hospital, the airport and many roads.
This is very low frequency! Long-term responses An exclusion zone was set up in the volcanic region. The town of Futaleufu, with about 1, residents, was also evacuated. It is tectonically active with earthquakes and occasional volcanic eruptions. In addition, volcanic ash from the eruption clouds caused ground transportation and health problems in Chile and Argentina.
In this southern part of the subduction zone the oceanic plate dips at a steep angle, while the northern end may be experiencing flat-slab subduction in which the oceanic slab slides beneath the continental plate at a very low angle. Chile stufy has 20 volcanoes with completed geological studies, 7 which have had hazard assessments and 7 more that are monitored. Before it had been dormant for over years. The ash cloud was up to 17 kilometers high and was visible on satellite images for hundreds of kilometers over the Leedc.
New roads and airport were built.
A risk map was created and is continually updated. This area of Chile volcamo reasonably low population density, so limits the potential impacts on the local scale.
The capital, Plymouth, has been covered in layers of ash and mud. The small ,edc of the island 11, people was evacuated in to the north of Montserrat as well as to neighbouring islands and the UK.
S EC Marine life was destroyed because the sea was poisoned by ash. There were s everal hundred domestic flights in Argentina and Chile and several dozen international flights from Santiago, Chile and Buenos Aires, Argentina cancelled. It measures 16km long and 11 km wide.
LEDC volcano case study
When the volcano began erupting in Mayit produced high Plinian eruption columns of ash, gas and rock. Volcanic eruptions and lahars have destroyed large areas of Montserrat. The island used to be self-sufficient, but became dependent on food aid. Airports in Chile, Argentina and Uruguay, up to etudy, km from the volcano, were forced to close or cancel flights.
People have returned to the island volccano recently. Local Helicopters could only reach the East side of the island due to ash in the air creating problems with reaching survivors. During this time, Montserrat was devastated by pyroclastic flows.
People felt it wasn’t enough which caused riots International Red cross provided water, food and shelter.
Evacuations began from South to North, but it was a slow process. EC S D houses completely destroyed.

Rivers channels became blocked too causing flooding. Services in the north of the island were expanded. The dome collapsed resulting in 5 million cubic metres of ash and dust pyroclastic flows in several directions enveloping the surrounding area.
This is a destructive margin, where the denser Nazca plate is subducted beneath the Less dense continental lithosphere of the South American plate.

Production of associated hazards from volcanoes. At this margin, clearly marked on the map and cross section opposite, there is oceanic to continental convergence. Smaller communities to the southeast such as Chubut and Rio Negro also received heavy ash falls.
Once Chances Peak had woken up it then remained active for five years. S Little infrastructure left untouched in the South to help provide emergency levrl for people. It’s split into 3 sections:
