The fissure opened on the north side of Fimmvörðuháls, directly across the popular hiking trail between Skógar, south of the pass, and Þórsmörk, immediately to the north. On 14 April 2010 Eyjafjallajökull resumed erupting after a brief pause, this time from the top crater in the centre of the glacier, causing "jökulhlaup" (meltwater floods) to rush down the nearby rivers, and requiring 800 people to be evacuated. This eruption was explosive, due to meltwater getting into the volcanic vent. It was estimated to be ten to twenty times larger than the previous one in Fimmvörðuháls. This second eruption threw volcanic ash several kilometres up in the atmosphere, which led to air travel disruption in northwest Europe for six days from 15 April to 21 April 2010 and again, in May 2010, including the closure of airspace over many parts of Europe. The eruptions also created electrical storms. On 23 May 2010, the London Volcanic Ash Advisory Centre declared the eruption to have stopped, but stated that they were continuing to monitor the volcano. The volcano continued to have several earthquakes daily, with volcanologists watching the volcano closely. As of August 2010, Eyjafjallajökull was considered dormant. Infrasound sensors have been installed around Eyjafjallajökull to monitor for future eruptions.', 'As of August 2010,']}}]}, {'provenance': [{'wikipedia_id': '26964386', 'title': '2010 eruptions of Eyjafjallajökull', 'section': 'Section::::Health effects.\n', 'start_paragraph_id': 67, 'end_paragraph_id': 67, 'meta': {'evidence_span': ['(First eruption on 20\xa0March 2010).
