The last phreatic eruption occurred on February 28, 2022. Seismicity remains stable. There is an increase in the number and duration of short tremors of low amplitude. Volcanic tremors are distal and associated with local faults. Geodetic monitoring shows a slight contraction of the volcanic edifice. Read all

OVSICORI-UNA reported that a point of incandescence on the SW wall of Turrialba's Cráter Oeste was visible on 23 February and was coincident with the area of strongest gas emissions. At 1955 on 27 February an eruption produced a diffuse ash plume that rose 300 m above the summit and drifted NE. Rumbling heard on 28 February was sometimes coincident with minor ash emissions.

Thu, 10 Feb 2022, 09:27OVSICORI-UNA reported that at 1259 on 6 February a small phreatic eruption at Turrialba's Cráter Oeste produced an ash plume that rose 100 m above the crater rim. A thermal anomaly from the floor of Cráter Oeste was identified in satellite images on 4 February. The anomaly was last seen in the same location on 25 January, and twice in 2021, during clear weather conditions; the location of the anomaly was the same in those images since March 2021, and likely represented a hot crack venting on the crater floor.

OVSICORI-UNA reported that periodic eruptive events, lasting 1-2 minutes each, were recorded at Turrialba's West Crater during 19-24 January. At 0546 on 19 January an eruption produced an ash plume that rose 200 m above the summit and drifted W. A small eruption at 1052 generated a plume that rose 50 m and drifted NW. Read all
Tue, 18 Jan 2022, 14:16OVSICORI-UNA reported that incandescence from Turrialba's West Crater was visible overnight during 15-16 January. Eruptive events were recorded at 2126 and 2132 on 17 January; the second event was stronger and produced an ash-and-gas plume that rose 1 km above the crater. Ashfall and a sulfur odor were reported by residents in Coronado, Tres Rios (30 km SW), Alajuela (50 km W), and Santa Ana (46 km WSW). Read all
