The eruption continues at the main crater of Taal on January 13, characterized by magmatic and hydrovolcanic activity; it generated lava fountains 500 meters high surmounted by dark gray plumes charged with vapor reaching about 2 kilometers high which scattered ash to the southwest and west of the main crater. Volcanic lightning was observed at the base of the degassing plumes this morning.
New vents have opened on the northern flank where short 500 meter lava fountains and in the main crater where plumes of steam have emanated.
Sulfur dioxide (SO2) emissions were measured at an average of 5,299 tonnes / day on January 13, 2020.
The lava fountains generated dark gray plumes loaded with steam of 800 meters high which drifted towards the general southwest on January 14 in the morning.
TAAL Volcano Eruption in Philippines (Jan 12, 2020)
Heavy ash falls from the continuous activity of the Taal volcano are reported in the municipalities of Lemery, Talisay, Taal and Cuenca, Batangas.
There have so far been no reports of major casualties or damage. A truck, however, skidded and fell to the side on an ash-covered road, killing the driver and injuring three companions in the southern province of Laguna in an accident that police said could be linked to slippery road conditions .
Government disaster agency and other officials have reported that more than 30,000 villagers have fled their homes in the hard-hit province of Batangas and neighboring Cavite, but officials expect as the number increases, hundreds of thousands more diverge from danger.
Some residents were unable to leave the ash-covered villages immediately due to lack of transportation and poor visibility. Others refused to leave their homes and farms.
The danger lies in the collapse of the roofs of dwellings, overloaded by the thick layer of sticky ashes.

The Philippine Seismic Network recorded a total of two hundred and twelve (212) volcanic earthquakes in the Taal region at 2:00 p.m. on January 14, 2020. Eighty-one (81) of these earthquakes were felt with intensities ranging from intensity I - V to Tagaytay City, Cavite.
New cracks or fissures were observed at Sinisian, Mahabang Dahilig, Dayapan, Palanas, Sangalang, Poblacion, Lemery; Pansipit, Agoncillo; Poblacion 1, Poblacion 2, Poblacion 3, Poblacion 5, Talisay and Poblacion, San Nicolas. A crack has also been documented across the road from Agoncillo to Laurel, Batangas.
The intense seismic activity coupled with a cracking in the caldera region probably means a continuous intrusion of magma under the Taal building, which can lead to additional eruptive activity.
Alert level 4 remains in effect on the Taal volcano.

Fernandina - Areas with the presence of thermal alerts detected by FIRMS, during the eruptions of 2017, 2018 and 2020 - Doc. Nasa / IGEPN - F. Vásconez
The eruption at Fernandina, in the Galapagos archipelago, which started shortly before 6.10 p.m. on January 12, 2020, from a circumferential crack located under the eastern edge of the caldera to an altitude of about 1300-1400 m above sea level, caused the emission of lava flows on the eastern flank. A cloud of volcanic gas was also observed at a height of approximately 1500-2000 m above the level of the crack (~ 3-3.5 km above sea level) and moving towards the west -North West. The eruption was observed by the park guards of the Galapagos National Park from the Bolivar Canal station.
In the past few hours, the level of seismic activity, the emission of volcanic gas and thermal anomalies have decreased significantly, indicating a rapid decrease in eruptive activity, similar to what happened in 2017 and 2018. It is important to indicate that on other occasions (Fernandina 2009, Wolf 2015, Sierra Negra 2018), an initial drop in initial activity was followed by a second eruptive phase.
The last eruption of this volcano occurred 19 months ago (June 16-18, 2018)

The situation changes little at Piton de La Fournaise, where on January 13, 21 volcano-tectonic earthquakes under the summit (the largest of M0.94) and 4 landslides were recorded.
The GPS of the summit area and in the far field record an inflation, corresponding to the pressurization of a surface and deep source.

Piton de La Fournaise - illustration of the deformation between 14.11.2019 and 14.01.2020. Here are represented baselines (variation in distance between two GPS receivers) crossing the Piton de la Fournaise building, at the top (top), at the base of the terminal cone (in the middle) and in the far field (bottom ). An increase is synonymous with elongation and therefore swelling of the volcano; conversely, a decrease is synonymous with contraction and therefore deflation of the volcano. Any periods colored in light pink correspond to eruptions. - Doc. OVPF
