Vulnerability This area of Chile has reasonably low population density, so limits the potential impacts on the local scale. A risk map was created and is continually updated. These columns were accompanied by pyroclastic flows, lahars, and abundant ash fall. D Loss of income from industries, lower standard of living conditions and quality of life. These are the causes of this volcano, which is explosive because the lava is Rhyolitic, has high gas pressure and high Silica content. By late May the lava eruptions had created a new dome of ,m 2 containing 55million m 3 of material. The impact of the event social, economic, environmental , in the short and longer term.
Once Chances Peak had woken up it then remained active for five years. In addition, volcanic ash from the eruption clouds caused ground transportation and health problems in Chile and Argentina. Airports in Chile, Argentina and Uruguay, up to 2, km from the volcano, were forced to close or cancel flights. The presence of the volcano resulted in a growth in adventure tourism. When the volcano began erupting in May , it produced high Plinian eruption columns of ash, gas and rock. Before , it consisted mainly of a rhyolitic lava dome that was last active 9, years ago.
The ash cloud could be seen from space and the volcano increased in size greatly due to lava deposition.
The nature of the hazard type, magnitude, frequency This volcano has a history of eruptions but in human terms it is infrequent. These are the causes of this volcano, which is explosive because the lava is Rhyolitic, has high gas pressure and high Silica content. The volcano had been dormant for over years but started to erupt on the 18 th of July Once Chances Peak had woken up it then remained active for five years. Despite the evacuations, 19 people were killed by the eruptions as a small group of people chose to stay behind to watch over their crops.
The capital, Lecel, has been covered in layers of ash and mud. Source Click here for cleaner image.
LEDC volcano case study – Revision Notes in A Level and IB Geography
The graphic shows the progress of the eruption and its impact on the island. It is part of stuy Leeward Islands in a chain of islands known as the Lesser Antilles. Following this Chances Peak remained active for five years.
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. These columns were accompanied by pyroclastic flows, lahars, and abundant ash fall.
This eruption had no real time monitoring of its eruption until a foreign agency, the USGS, arrived on the 16 th of Maya full 15 days after the first eruption.
Airports and highways were closed due to the ash dangers, both in Chile and neighbouring countries, eg Argentina. The airport was buried by Lahars on 11 February Short-term responses Large scale evacuation by the British Navy Abandonment of the capital city, Plymouth Compensation and redevelopment money donated by the UK government Unemployment rose due to the collapse of the tourist industry.

It measures 16km long and 11 km wide. S EC Water supplies were contaminated. EC S D Population volxano from 12, to 5, Sign up to Comment.
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. The z pollution generated by the ash volcani health problems for people. During this time, Montserrat was devastated by pyroclastic flows. Human factors affecting risk and vulnerability – Volcanoes. Local Helicopters could only reach the East side of the island due to ash in the air creating problems with reaching survivors.
Between and Montserrat was devastated by pyroclastic flows. The impact of the event social, economic, environmentalin the short and longer term.
S EC Marine life was destroyed because the sea was poisoned by ash. Real-time seismic monitoring began on 16 th of Mayand that was cae by the USGS, not a domestic agency.
The remote location of the volcano and the low population density meant that the management of this volcano was not high, despite its long term explosive past.
LEDC Volcano Case Study: Montserrat
Montserrat Background British colony in the Caribbean. In the volcano began to give off warning signs of an eruption small earthquakes and eruptions ,evel dust and ash.
Beforeit consisted mainly of a rhyolitic lava dome that was last active 9, years ago. Volcanic eruptions and lahars have destroyed large areas of Montserrat. This is very low frequency!
