Dr. Alka Tripathy-Lang, Ph.D. (@DrAlkaTrip) reports: "Before Sunday, Jan. 12, the Philippine volcano Taal was at Alert Level 1, out of 5, indicating a low level of abnormal activity. At 1 p.m. local time, the Philippines Institute of Volcanology and Seismology, PHIVOLCS, began to raise the alert level, and by 7:30 p.m. that day, they issued an Alert Level 4, indicating that a hazardous explosive eruption is possible within hours to days."
VW alum Dr. Chuck Wood added "Taal is an ashflow volcano (or super volcano) that has in the past had massive eruptions that sent ash around the world and often caused significant climate cooling. There has not been such a massive eruption anywhere in the world since modern science developed and we don’t know if a given precursor signals a normal eruption or a very large one. Yellowstone Natl Park is in a similar mega-caldera that has had recent episodes of inflation, but no eruption"
Scenes of #Etna's new, sub-terminal eruption, during the night of 30-31 May 2019, seen from Santa Venerina, Fiumefreddo and (last photo) Tremestieri Etneo. "Sub-terminal" means the eruption is occurring close to the summit craters, generally at around 2900-3000 m elevation. [Image and summary from Boris Behncke (@etnaboris)]

In this week’s Volcano Watch article – as well as a recent radio interview – the USGS Hawaiian Volcano Observatory is again saying that the 2018 eruption of Kīlauea Volcano was not triggered by Puna Geothermal Venture.
