What causes volcanoes As of Dec. 4, 2019, the current volcano alert level for Mount Pele is yellow. The La Soufrire volcano in Saint Vincent and the Grenadines has seen an increase in eruptive activity, with multiple explosions starting on Friday, April 9, triggering pyroclastic flows - dangerous and fast-moving avalanches of hot ash and gas. )industry: 7.8% (2017 est. A period of tremor and vigorous ash venting followed about an hour later. )government consumption: 50.4% (2017 est. We postulate that localised extensional stress conditions near the linear VT activity, due to interaction with stresses in the overriding lithospheric plate, may encourage normal fault growth and promote sector weaknesses in the volcano. , AQA A-level Geography 7037 - Paper 1 - 22nd May 2019 , The island is on a destructive plate boundary- the North American plate (denser) subducted by the Caribbean plate, Convection currents pulled the North American plate into the mantle-> heat+ friction -> the rock melted-> molten rock was lighter than the surrounding rock-> rose through cracks towards the Earth's surface-> volcanic island, Chances Peak Volcano erupted+ produced thick sticky lava (andesite)-> builded up at the top of the volcano in a dome-> became too heavy-> the dome collapsed-> huge ash cloud formed, The domecollapsed-> rocks, gases+ ash were ejected from the volcano-> pyroclastic flows (fast moving+ destroyed everything on their path), Strong winds blew the clouds of ash westwards over the island, Suffered blackout conditions- due to the sun being obstructed by the ash cloud, The eruption of the volcano should not have had a major impact on the people, as the areas affected were in the Exclusion Zone set up after an eruption in 1995. The general trend of the eruption so far has been slow escalation (Figure 2). As of Jan. 21, the current volcano alert level for La Soufrire is orange.

CNN: A Major Volcanic Eruption In Santorini Is 'A Matter Of Time', Standard & Poors rating: BBB- (2020)note: The year refers to the year in which the current credit rating was first obtained. By late-1996, as magma effusion rates escalated, most seismic events were originating within a volume about 2 km diameter which extended up to the surface from only about 3 km depth - the diminution of shear failure earthquakes suggests the pathway for magma discharge had become effectively unconstricted. The eruption was preceded by three years of elevated seismic activity and a more intenseearthquake swarmthat began on July 14. It is entirely submarine and has had eight small eruptions between 1937 and 1977. )arable land: 20% (2018 est. However, a NE-SW alignment of epicentres beneath the NE flank of the volcano emerged in one swarm of volcano-tectonic earthquakes (VTs) and later nests of VT hypocentres developed beneath the volcano and at a separated location, under St. George's Hill.
