Coseismic Displacement of 1987 Earthquake from Aerial Images

by Daniel Melnick 8 December 20226 December 2022

Differencing digital surface topography models constructed from historical aerial photographs reveal the coseismic surface displacement field of the 1987 earthquake in northern New Zealand.

Side-by-side images show fish-eye-style photographs of a starry evening sky illuminated by different subauroral events. The left image shows a SAR arc, a reddish arc that spans the sky. Beneath the arc the sky transitions from bright green at the horizon to purple and is partially obscured by clouds. The right image shows a STEVE phenomenon. Part of the red SAR arc is still visible but is much fainter and more of a pink color than its original red. The green and purple sky is more muted in color, and more stars and the band of the Milky Way are now visible. In both images, the silhouette of some shrubs is visible.

From SAR Arc to STEVE: An Atmospheric Evolution

by Alexandra K. Scammell 6 September 20227 September 2022

A new study reports the first observation of a stable auroral red arc evolving into a strong thermal emission velocity enhancement during a geomagnetic storm.

Four-paneled figure, with the upper right panel showing Today Show coverage, with both the initial question directed to the @USGSVolcanoes Twitter account from user @JayFurr, “Is it safe to roast marshmallows over volcanic vents?” and the response, “Erm…we’re going to have to say no.” The upper left panel shows CNN coverage with an image of the eruption and the headline “USGS: ‘Please don’t roast marshmallows over lava.’” The lower left panel shows MSNCB coverage, which shows only the initial tweet. The lower right panel shows MSNBC’s parody of the NBC public service announcement graphic, in which, against the background of space filled with stars, the purple words “The S’more You Know” are underlined by a yellow shooting star.

Roosters, S’mores, and #EmergencyCute: A Humor-in-Crisis How-To

by Alka Tripathy-Lang 15 July 202230 August 2022

When natural hazards strike communities, we may not think science agencies should respond with humor. Researchers suggest that sometimes, however, humor can connect communities and bring smiles.
