Shannon Hall

S. Hall

Shannon Hall, a freelance science journalist, covers topics ranging from geysers to galaxies. Over the past 8 years she has received four degrees—two bachelor’s degrees in astronomy and philosophy and two master’s degrees in astronomy and science journalism—and has lived in eight different states. For the moment she has settled down in Hanover, N.H., happy to be a tiny dot in a big landscape.

A New Tool to Better Forecast Volcanic Unrest

Shannon Hall by S. Hall 8 July 20161 November 2022

In a retrospective study of volcanic unrest at Indonesia's Kawah Ijen, a new model was able to pick up on the rising probability of eruption 2 months before authorities were aware of the risk.

Tsunamis Splashed Ancient Mars

Shannon Hall by S. Hall 19 May 201628 January 2022

Massive meteorites likely slammed into a Martian ocean billions of years ago, unleashing tsunami waves up to 120 meters tall, a close study of a region of the Red Planet's terrain has found.

This relatively recent impact crater photographed last year spans a little more than a kilometer in the Sirenum Fossae region of Mars.
