UNDERSEA VOLCANIC ERUPTION SEEN FROM SPACE
UNDERSEA VOLCANIC ERUPTION SEEN FROM SPACE: An undersea volcano erupted today, Jan. 15th, near the Pacific island of Tonga, sending large tsunami waves crashing on shore and people rushing to higher ground. Japan's Himawari-8 weather satellite recorded this dramatic video.
It shows a huge plume of ash, steam and gas rising like a mushroom above the blue Pacific waters. "Not only that, but also an atmospheric shock wave can be seen," points out M. Shiraishi, who created the animation for the Space Weather Gallery. "The terminator between daylight and night caught up with the shock wave. This means the terminator runs faster than the speed of sound."
The shockwave was recorded as a sudden uptick in air pressure as far away as Alaska, Belize and multiple locations in Florida. The global wave is expected to converge on southern Algeria, giving an especially strong signal there.
High-altitude balloon and satellite measurements indicate that the exhaust plume has reached the stratosphere, as high as 60,000 feet. Ash and sulfurous compounds spreading through the stratosphere could create unusual sunsets in the evenings ahead. Stay tuned for sightings.
