Nasa | Sarychev Volcano Eruption international space station

When the Hunga Tonga-Hunga Ha'apai volcano erupted on Jan. 15, it sent a
tsunami racing around the world and set off a sonic boom that circled the globe
twice. The underwater eruption in the South Pacific Ocean also blasted an
enormous plume of water vapor into Earth's stratosphere - enough to fill more
than 58,000 Olympic-size swimming pools. The sheer amount of water vapor
could be enough to temporarily affect Earth's global average temperature. So
outside of its sheer magnitude, what makes this eruption so unique?
