Wed, 29 May 2024, 14:00INSIVUMEH reported that eruptive activity continued at Santa Maria's Santiaguito lava-dome complex during 21-28 May with continuing lava extrusion and block collapses and avalanches at the Caliente dome. Sometimes the avalanches are audible several kilometers away. Incandescence from the dome was visible during most nights and early mornings, and occasional incandescence was also present along the upper parts of the lava flow on the WSW flank.

Wed, 29 May 2024, 14:00Observatorio Vulcanológico y Sismológico de Popayán, Servicio Geologico Colombiano (SGC) reported that seismic activity at Puracé decreased during 21-24 May and continued to be at pre-29 April levels. Both volcanic tremor (VT) associated with rock fracturing and long-period (LP) events associated with fluid movement were located less than 2.5 km beneath Puracé crater and had low magnitudes. Gas emissions from the crater and the N flank fumarole were occasionally visible in webcam views.

Wed, 29 May 2024, 14:00In a special notice for Kanlaon, PHIVOLCS stated that the seismic network detected 24 volcano-tectonic earthquakes during 1335-1630 on 26 May with local magnitudes of .8-2.3 and depths of 0-6 km beneath the W flank. Sulfur dioxide gas emissions from the summit crater had been elevated since 1 January, averaging 1,291 tonnes/day (t/d); the most recent measurement was 2,003 t/d, recorded on 26 May. Ground deformation data from continuous GPS and electronic tilt data had been recording inflation at the volcano since March 2022.
