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
