“It was an astonishing experience to see the changes taking place 300 miles away with no one anywhere nearby, and the data flowed back to land at the speed of light through the fiber-optic cable
Delaney organized a workshop on campus in mid-April at which marine scientists discussed how this high-tech observatory would support their science. Then, just before midnight on April 23 until about noon the next day, the seismic activity went off the charts. The gradually increasing rumblings of the mountain were documented over recent weeks by William Wilcock, a UW marine geophysicist who studies such systems. During last week’s event, the earthquakes increased from hundreds per day to thousands, and the center of the volcanic crater dropped by about 6 feet in 12 hours.
“The only way that could have happened was to have the magma move from beneath the caldera to some other location,” Delaney said.
