Kanlaon volcano (Philippines) - Smithsonian / USGS Weekly Volcanic Activity Report for 19 July-25 July 2023 (Continuing Activity)

PHIVOLCS issued a special notice for Kanlaon at 1000 on 21 July, noting increased seismicity. The seismic network detected 35 volcano-tectonic earthquakes between 2200 on 20 July and 0906 on 21 July at depths of 12-15 km beneath the summit crater. The earthquakes had local magnitudes of 0.9-2.3. Read all

Kanlaon volcano (Philippines) - Smithsonian / USGS Weekly Volcanic Activity Report for 3 May-9 May 2023 (New Activity / Unrest)

PHIVOLCS issued a special notice for Kanlaon at 2030 on 4 May, noting increased seismicity and ground deformation, and ongoing elevated sulfur dioxide emissions. Ground deformation data from continuous GPS and electronic tilt data indicated short-term inflation of the lower and mid-flanks of the volcano since March, though during the second week of April inflation was pronounced at the SE mid-flank. Real-time, continuous gas monitoring of thermal springs on the N flank detected sulfur dioxide for the first time beginning in April. Read all

Kanlaon volcano (Philippines) - Smithsonian / USGS Weekly Volcanic Activity Report for 26 April-2 May 2023 (New Activity / Unrest)

PHIVOLCS issued a special notice for Kanlaon at 0700 on 1 May, noting increased sulfur dioxide emissions. Real-time, continuous volcanic gas monitoring of thermal springs on the N flank detected sulfur dioxide for the first time beginning in April. On 30 April a Flyspec instrument measured an average of 1,099 tonnes per day of sulfur dioxide emissions at the summit crater, a value which was significantly higher than the average of 124 tonnes per day measured since March.
