Philippines: Mayon Volcano Eruption Snapshot (as of 24 January 2018)
On 22 January 2018, alert level-4 (hazardous eruption imminent) was raised over Mayon Volcano. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) raised the alert level after a 10 km high ash column spewed out of the volcano. Alert level-3 (increased tendency to hazardous eruption) has been in effect since 14 January, when a phreatic eruption ejected ash and sulphur fumes.
The danger zone has been extended to a 9 km radius where local authorities were advised to prevent any human activity due to the danger of rockfalls, landslides and sudden explosions or dome collapse that may generate hazardous volcanic flows.
