Dozens of mild magmatic and phreatic eruptions have been recorded. The last recorded eruption was on 23 January 2018. Given the prolonged duration of the emergency and with the instruction of the head of the district, the exclusion zone was reduced to 6 KM and may likely be reduced even further. The number of evacuees has also declined. By 30 January 2018, official records reports show 23,682 evacuees in 185 evacuation sites across 9 districts. (IFRC, 13 Feb 2018)
