Session description:

The 15 January 2022 eruption of Hunga Tonga-Hunga Ha’apai in the Tonga
Islands was unprecedented in modern times. It was one of the largest
volcanic explosions of the instrumental era and also caused atmospheric
shockwaves that circled the globe. The eruption produced a tsunami that
traveled throughout the Pacific and was also observed at locations in
the Atlantic Ocean and the Mediterranean Sea. We welcome papers on the
eruption, the atmospheric waves, any sources and characteristics of the
tsunami, remote or nearby measurements of any of the associated
phenomena, as well as threat assessment and communications and impacts.

Conveners: Peggy Hellweg, University of California, Berkeley; Lori A.
Dengler, Humboldt State University; Emile A. Okal, Northwestern
University; Seth Moran, U.S. Geological Survey; Stuart Weinstein, PTWC;
Summer Ohlendorf, NTWC.

Deadline: Tuesday, 8 March 2022 at 5 p.m. Pacific.
