This Friday January 7, 2022 from 00:20 TL (23:20 on January 06, 2022 local time) a new fissure eruption is evident at the level of the volcano WOLF, on Isabela Island in the Galapagos archipelago.

Seismic recording from the FER1 station, located in the Galapagos Islands, shows that at approximately 9:00 p.m. local time in the Galapagos, a seismic swarm occurred. At 9:35 p.m., an earthquake of magnitude 2.4 was recorded, with its epicenter at the Wolf volcano.

From 11:15 pm TL Galapagos, a tremor signal can be observed, probably associated with the onset of the eruption. All of these signals were of low amplitude because the FER1 station is located on Fernandina Island.

At 01:20 TL (00:20 TL Galapagos) on January 07, 2022, a cloud of gas and ash is visible on satellite images, reaching heights between 3,793 m asl in the northeast (NE) and 1,943 m asl in the west (W); There is no population near the volcano or towards the ash clouds.

The FIRMS satellite system shows several thermal alerts located on the southern and southeastern flanks of the volcano. These alerts are associated with the high temperatures generated by the eruptive fissure and lava flows.

The last activity of the Wolf volcano was recorded in 2015, from May 25 to June 2 (GVP).
