Philippines - Volcanic unrest (ECHO 09 Jun 2023)Fri, 09 Jun 2023 10:57

  • Mayon volcano, located in the province of Albay, Bicol Region, central Philippines, is in a state of unrest following six dome-collapse Pyroclastic Density Currents (PDC) and several rockfall events that drifted along the southern gullies within two kilometres from the summit crater. Lava flow, ash and gas emissions were also recorded by the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
  • PHIVOLCS raised the alert level to 3 which means that all the people living within the 6-km radius (Permanent Danger Zone) from the crater of the volcano are recommended to evacuate.
  • The Department of Social Welfare and Development (DSWD-DROMIC) planned evacuation centres, tents and basic necessities for the projected 15,000 families living within the 6-km permanent danger zone.
  • DG ECHO field offices and partners are monitoring the situation and are ready to assist affected population in case of need.
Philippines - Volcanic activity, update (ECHO 13 Jun 2023)Tue, 13 Jun 2023 10:35

  • In the past 24 hours, the activity of Mayon volcano (located in Albay Province, Bicol Region, central Philippines) was characterized by very slow lava flows moving approximately 1 km from the crater, one volcanic earthquake and moderate ash emission drifting northeast as reported by the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
  • The National Disaster Risk Reduction Management Council (NDRRMC) holds full-council emergency meeting in the morning of 13 June with DG ECHO partners observing. Seven (7) Local Government Units (LGUs), Tobaco, Malilipot, Daraga, Camalig, Guinobatoan, Ligao, and Santo Domingo have evacuated 14,865 individuals (4,159 families) in 22 evacuation centres as of 13 June.

Philippines - Volcanic unrest, update (ECHO 15 Jun 2023)Thu, 15 Jun 2023 09:53

  • The state of unrest of the Mayon volcano in the central Philippines is still ongoing. In the past 24 hours, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) recorded two volcanic earthquakes, a very slow effusion of lava from the summit of the crater and steam-laden plumes that rose 700 m.
  • According to the National Disaster Risk Reduction Management Council (NDRRMC), almost 18,000 have been displaced (17,216 evacuated in 25 evacuation centres), and 37,682 people have been affected across 26 Barangays of the Albay Province in Bicol Region.
  • The alert level of the volcano stands at 3 which means that the volcano is currently in a relatively high level of unrest as magma is at the crater and hazardous eruption is possible within weeks or even days.

Updates on volcanic activity (Smithsonian)

The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Mayon report has been published on 21 Jun 2023 08:24.
PHIVOLCS reported that lava-dome extrusion at Mayon?s summit crater continued during 14-20 June, generating frequent lava flows and pyroclastic density currents (PDCs, or pyroclastic flows), and additional evacuations. Sulfur dioxide emissions ranged from 149-193 tonnes per day (t/d) during 13-14 June, rising to 826-1,004 t/d during 15-18 June (above normal baseline values of 500 t/d), and then dropping to 389 t/d on 19 June. The total number of rockfalls ranged from 265-309 events per day, resulting from partial collapses of the growing lava dome and lava flows. PDCs were recorded during 13-14 June (7), 14-15 June (3), 15-16 June (13), 16-17 June (9), 17-18 June (11), 18-19 June (5), and 19-20 June (2); each event lasted 2-6 minutes based on seismic signals. Lava flows remained active, with debris collapses throughout the week sending material into the Mi-Isi (S) and Bonga (SE) drainages. By 20 June lava flows reached 2.5 km down the Mi-Isi and 1.8 km down the Bonga drainages, and debris flows extended 3.3 km from the crater. Ashfall during 15-16 June was reported in the communities of Buga (36 km W), Nabonton (9 km W), Ligao (16 km W), Purok 7 (12 km S), and San Francisco (11 km SW). The Disaster Response Operations Monitoring and Information Center (DROMIC) reported that by 20 June there had been 38,975 people affected, 20,139 displaced, and 18,749 taking shelter in 28 evacuation centers across Albay. The Alert Level remained at 3 (on a 0-5 scale), and residents were reminded to stay away from the 6-km-radius Permanent Danger Zone (PDZ).
