Onderwater vulkaan voor de kust bij Oregon (V) staat op uitbarsten

[4seasons]

Een video met uitleg en meer publicaties met nog een video over de onderwatervulkaan voor de kust van Oregon (staat Washington VS)
Onderzoek is uitgevoerd door medewerkers van NOAA (Earth-Ocean Interactions)

De onderzoekers hebben afgelopen week o.a. het volgende geconstateerd:
April 30, 2015 - It looks like an eruption
The temperature data from the bottom pressure/tilt instruments are showing increases that suggest that lava was erupted on the seafloor somewhere nearby.
Check out the latest data here. Below is the same long-term inflation/deflation plot as below, but now with the 2015 eruption added.
Note however, that I've just eyeballed it in a vertical sense (on the Y-axis). 
Until we go out in August and repeat our ROV-based pressure measurements (the purple dots), we won't know exactly where it fits, nor the drift of the OOI pressure sensor. 
But I don't think this is too far off. See the OSU Press Release here.

On the evening of 23 April, seismometers around Axial recorded a huge spike in seismic activity. Small earthquakes began rattling at a rate of almost 8,000 per day, a nearly tenfold increase from before. William Wilcock, an oceanographer at the University of Washington, spotted the spike and alerted a group of scientists who, a day earlier, had just finished a planning workshop about what to do when Axial erupted.
