While Indonesia bore the brunt of the damage, the Krakatau eruption had perplexing effects across the world. Montserrat lies on a destructive platemargin meaning the volcanolies at the boundary between an oceanic and continental plate. 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.

NASA is continuing efforts to monitor and assess the volcanic activity using Earth-observing data in order to provide guidance and situational awareness for decision-making. An eruption looked likely-> the workers evacuated safely by responding to the emergency sirens. The island's sugar plantation economy was converted to small farm landholdings in the mid-19th century. Volcanoes erupt when hot, buoyant magma rises to the surface from deeper within the earths crust. Disaster risk governance is concerned with how institutions change in response to perturbations or, conversely, are able to remain static for long periods of time. )hydroelectricity: 0% of total installed capacity (2020 est. Then something needs to trigger the eruption. They thought they would receive audible warning from the volcano as it was going to erupt-> this didn't happen-> were caught unawares, 19 people killed by the pyroclastic flows, 7 people killed by the surge in Streatham+ Windy Hill area, Villages affected by deposits: Dyer, Farrell's Yard, Windy Hill, Streatham, Harris, Farm and Trant, The villages of Farm and Trant- completely buried by ash flow deposits, The ash fell back on to some parts of the island-> deposited ash 2-3 mm thick, A total of 4 km2 of land was covered by deposits, Houses in the Exclusion Zone destroyed by impact of rock, up to 5m in size-> should have been empty, but 15 people were living in the Exclusion Zone-> mostly farmers-> were producing crops to feed evacuees, The pyroclastic surges spread out+ flattened trees on the ridge surrounding Farrell's Yark-> no vegetation was left, just bare vegetable beds+ the soil was baked hard. The explosive eruption was triggered by about 30% of the dome avalanching away in the previous 12 hours which decompressed gas-rich magma deeper in the volcano.

The high level of heat and activity inside the Earth, close to a volcano, can provide opportunities for generating geothermal energy. -the melt then raised up through overlying crust to form volcanic islands. We partner with people around the world toincorporate Earth observations into their work. As a lava dome grows it becomes unstable and parts of the dome can suddenly avalanche away and simultaneously disintegrate to form a flow of fragments and volcanic ash known as a pyroclastic flow.
