Since January 2018, over 90,000 people were evacuated due to the eruption of Mayon volcano. With still more than 65,000 people in evacuation camps at the beginning of March, the alert level was lowered from ‘4’ (hazardous eruption within days) to ‘3’ (hazardous eruption within weeks) on 6 March, which gradually allowed the majority of the displaced residents to return to their homes.
Since 14 January 2018, Mayon Volcano continues to show high level of unrest that has displaced tens of thousands of residents from the 6 - 9 km danger zone.
Alert level 4 (hazardous eruption imminent) remains in effect. Danger zone has been extended to 9 km radius up from previous 8 km where local authorities were advised to prevent any human activity due to the danger of rockfalls, landslides and sudden explosions that may generate hazardous volcanic flows.
Tropical Cyclone Gita passed Samoa on 10 February and Niue on 11 February, with damage and localized flooding reported in Samoa. TC Gita is forecast to strike Tonga on the evening of 12 February. As of 12 February, 12:00 UTC, TC Gita continues to move west as a Category 4 cyclone with winds of up to 213 km/h, it is expected to maintain this intensity as it passes over Tonga and into Fijian territorial waters. More than 80,000 people in Tonga are currently expected to be impacted by cyclone strength winds.
Displaced population (cumulative)
There were displacement incidents which happened in each quarter of 2017. As of 31 December 2017, 59,100 families remained displaced affected by Marawi Conflict and Severe Tropical Storm (STS) Tembin.
Tropical Storm Tembin (locally known as Vinta) intensified as it made landfall in Davao Oriental in the morning of 22 December and crossed various provinces across Mindanao and Palawan causing flash floods and landslides, destroyed houses and rendered several roads and bridges impassable. On 28 to 29 December 2017, a joint rapid assessment was conducted by the Autonomous Region for Muslim Mindanao – Humanitarian Emergency Action Response Team (ARMM-HEART) with support from the Mindanao Humanitarian Team (MHT).
Alert level-4 (hazardous eruption imminent) remains in effect over Mayon Volcano located in Albay province, 300 km southeast of Manila. The volcano is showing high levels of continuing unrest, with lava fountains and frequent ash explosions occuring several times a day, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS). On 28 January, day-long rainfall caused sediment-laden streamflows in channels draining from the volcano edifice, rendering several roads in Albay impassable.
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 alert level for the Mayon Volcano has been raised to Level-4 due to increased seismic unrest, lava fountaining and explosions. The volcano spewed a 10-kilometer high ash column on 22 January, with authorities warning of an imminent hazardous eruption, possibly within days. The eruption resulted in moderate to heavy ash fall, with low-visibility reported in the towns of Guinobatan, Camalig, and Ligao located to the southwest of the volcano.
Mayon Volcano generated steam driven eruptions on 13-14 January, that ejected ash and sulphur fumes accompanied by rumbling sounds. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) raised the alert to level-3 due to a relatively high level of unrest and the increasing possibility of a hazardous eruption within weeks or even days. On 15 January, rock falls, lava and pyroclastic flows along two kilometers of the volcano’s gullies are results of the lava dome collapsing.
Tropical storm Tembin (locally known as Vinta) crossed various provinces across Mindanao causing severe flooding, flash floods and landslides on 22 to 23 December 2017. Various humanitarian organizations present in Iligan City responding to Marawi conflict have conducted initial assessments and response.
ARMM HEART and Mindanao Humanitarian Team (MHT) Cluster leads and its local partners are undertaking needs assessment in Lanao del Sur province to support local government units in the humanitarian response.
Tropical storm (TS) made landfall in Davao Oriental in the morning of 22 December and crossed various provinces across Mindanao causing flash floods and landslides. Severe flooding and landslides have been reported in Cagayan de Oro City and in a number of towns in Lanao del Norte, Lanao del Sur , Zamboanga del Norte and Zamboanga Sibugay provinces. The Mindanao Humanitarian Team and its local partners are undertaking needs assessment and supporting local government units in the humanitarian response.
