Purace volcano (Colombia) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 May-14 May 2024 (New Activity / Unrest)

Observatorio Vulcanológico y Sismológico de Popayán, Servicio Geologico Colombiano (SGC) reported that the number of both volcanic tremor (VT) and long-period (LP) seismic events at Puracé were stable during 7-13 May with only a slight increase in both the number and intensity of LP events on 9 May. The VT events had low magnitudes and were located at depths up to 4 km beneath the volcano and its E flank. The largest VT events were a M 1.8 recorded at 2351 on 7 May and at 2202 on 10 May.

Purace volcano (Colombia) - Smithsonian / USGS Weekly Volcanic Activity Report for 1 May-7 May 2024 (New Activity / Unrest)

Observatorio Vulcanológico y Sismológico de Popayán, Servicio Geologico Colombiano (SGC) reported that the number of both volcanic tremor (VT) and long-period (LP) seismic events at Puracé increased during 23-29 April. The events had low magnitudes and were located at depths of 0-5 km; the VT events were located beneath the Puracé, Piocollo, and Curiquinga cones. Sulfur dioxide emissions had increased in the previous few weeks and carbon dioxide emissions continued to be above baseline levels at a fumarole on the N crater rim. Read all
