Volcano profile for Hollister Ridge in Undersea areas, including its current status, catalog data, nearby earthquakes and live map layers.
Live map
Official VAAC areas. Observations and forecasts have separate valid times.
NOAA-20 / VIIRS · detections within 20 km of catalogue volcanoes. A heat source does not confirm an eruption.
NOAA-20 / OMPS · total SO₂ column in Dobson units (DU), assuming a plume altitude of 3 km.
Total SO₂ columns show neither an individual volcano’s daily emission rate nor directly the concentration at ground level.
