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.
  • DG ECHO field offices and partners closely monitor the situation and coordinate with the national authorities for any need of immediate relief assistance.
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.
Philippines - Volcanic unrest, update (ECHO 27 Jun 2023)Tue, 27 Jun 2023 10:32

  • In the past 24 hours, explosive and effusive activity is ongoing. Lava flows of 1,600 and 1,200 meters in length have been registered in the southern and south-eastern gullies of the volcano as well as more than 100 volcanic earthquakes and an ash plume 750 metres high.
  • Following this unrest phase of the volcano, the National Disaster Risk Reduction Management Council (NDRRMC) reports more than 20,100 displaced people, of whom 18,706 evacuated in 28 evacuation centres, and almost 41,500 affected people across 26 Barangays in Albay Province.
  • 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.
Philippines - Volcanic unrest, update (ECHO 29 Jun 2023)Thu, 29 Jun 2023 10:09

  • On 28 and 29 June, Mayon Volcano continued to feed two lava flows that advanced for 2,100 meters and 1,300 metres along Mi-isi and Bonga gullies respectively in the south and south-eastern direction. In addition, an ash plume 1,000 metres high drifting west-northwest, north-northwest and northeast direction was registered by the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
  • As of 29 June, the National Disaster Risk Reduction Management Council (NDRRMC) reports almost 20,200 displaced people (of whom 18,754 evacuated in 28 evacuation centres)  and more than 41,500 affected people across 26 Barangays in Albay Province (Bicol Region, central-eastern Philippines).
  • According to PHIVOLCS, the alert level of the volcano stands at 3.

Philippines - Volcanic unrest, update (ECHO 01 Aug 2023)Tue, 01 Aug 2023 09:56

  • Explosive and effusive activity of the Mayon volcano, located in Bicol Region, central Philippines, is ingoing. In the past 24 hours, two main lava flows moving in southern and south-eastern direction and ash plumes 100 m high have been recorded by the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
  • According to the National Disaster Risk Reduction Management Council (NDRRMC), moret than 20,200 people are still displaced while almost 38,400 others have been affected across 26 Barangays located in Albay Province (Bicol Region). DG ECHO’s partners remain on the ground, providing assistance to displaced people.
  • The alert level of the volcano stands at 3, meaning the volcano is currently in a relatively high level of unrest as magma is at the crater and a hazardous eruption is possible within weeks or even days. PHIVOLCS continues to recommended that the 6-km radius Permanent Danger Zone (PDZ) remains evacuated.

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 26 Jul 2023 11:56.
PHIVOLCS reported that the eruption at Mayon continued during 19-25 July, with slow lava effusion from the summit crater feeding lava flows on the S, SE, and E flanks. The length of the lava flow in the Mi-Isi (S) drainage remained at 2.8 km and the flow in the Bonga (SE) drainage advanced to 2.8 km by 23 July. The lava flow in the Basud drainage on the E flank did not advance, remaining 600 m long. Collapses at the lava dome and from the lava flows produced incandescent rockfalls and pyroclastic density currents (PDCs, or pyroclastic flows) that descended the Mi-Isi, Bonga, and Basud drainages as far as 4 km. Seismicity was dominated by weak low-frequency volcanic earthquakes (LFVQs) originating from a shallow source and were associated with a rapid release of volcanic gases from the summit crater. Some of the events produced audible thunder-like sounds and short dark ash plumes that drifted SW. Between 1733 on 18 July and 0434 on 19 July there were 30 of these events (called ?ashing? by PHIVOLCS) recorded by seismic, infrasound, and visual and thermal monitors; each lasted 20-40 seconds long and generated ash plumes that rose 150-300 m above the summit. Sulfur dioxide emissions were reported on most days; variable amounts averaged between 1,581 and 3,135 tonnes per day, with the highest value recorded on 24 July. Each day seismic stations recorded 137-175 rockfall events, 3-4 PDC events, and 5-304 LFVQs. During 19-20 the network recorded three ashing events. At 1956 on 21 July a short-lived (28 seconds) ejection of lava was accompanied by seismic and infrasound signals. The Disaster Response Operations Monitoring and Information Center (DROMIC) reported that as of 1800 on 24 July there were 5,372 families, or 18,782 individuals, that were either in evacuation shelters or staying in other types of alternative housing. 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). PHIVOLCS recommended that civil aviation authorities advise pilots to avoid flying close to the summit.
