DESCRIPTION:In May 2018 a dramatic change occurred at one of the world’s
  most active volcanoes. On the Island of Hawai’i\, the eruptive activity
  of Kīlauea volcano shifted to the north-east as a series of fissures ope
 ned up in the quiet leafy neighbourhood of the Leilani Estates. At the sam
 e time\, the famous Halemaʻumaʻu lava lake sunk out of sight and the sum
 mit caldera collapsed\, subsiding hundreds of metres and leading to the ev
 acuation of the Hawai’i  Volcano Observatory (HVO) building\, now perche
 d precariously on the edge of the crater wall. Declared a national emergen
 cy\, the eruption was of unprecedented scale and presented an extreme moni
 toring challenge for the HVO of the United States Geological Survey (USGS)
 . \n\nIn July-August\, a group of volcanologists from the Cambridge and Le
 eds universities headed out to Hawai’i at the invitation of the USGS\, t
 o sample the ongoing eruption. Our goal was to characterise the chemistry 
 of the erupting plume from source to exposed communities around the island
 \, with a special focus on the particulate aerosol phase of the volcanic p
 lume(s). \n\nRemarkably\, the eruption ended on the final-day of our three
 -week campaign. It buried 716 houses\, ~35km^2 of land and created ~3.5km^
 2 of new land where the vast lava flows reached the ocean. The question ev
 eryone wants to know the answer to now is what next for Kīlauea?
