Volcanoes Wider Reading Case Study - Kilauea, Hawaii - 2018
Shield volcano - low with gently sloping sides - formed from layers of lava
Kilauea’s main mode of destruction is lava
On this occasion, fissures opened to the east of the volcano releasing lava close to built up areas
Residents ordered to evacuate - including 1,500 population of Panoa
Eruption ongoing for a month
Eruption estimated to be wither VEI-0 or VEI-1
Extensively monitored by the United States Geology Survey (USGS)
Lava destroyed 82 properties
Scientists of the US Geology Survey’s Hawaiian Volcano Observatory (HVO) have instruments that monitor the rift zones 24 hours a day
Inhabitants of the island are encouraged to develop an evacuation plan including locations they can stay should their property be at risk from a lava flow
High levels of toxic gas emissions from the eruptions could present health problems in the future for Hawaii’s residents
Volcanic smog (vog) - contains mostly sulphur dioxide and acid particles along with ash - air quality concern
Molten rock travelled to coast - began pouring into cool seawater - created clouds of lava haze (“laze”)
People warned to stay away as plumes can travel up to 15 miles downwind
No deaths from vog related symptoms
