by Suzana Camargo 26 July 202221 September 2022

Hurricane winds can lead to coast downwelling, which brings warmer surface water near the coast and can contribute to the intensification of the landfalling hurricane.

Mapping a Volcanic Eruption in the Backyard of Iceland’s Capital

by Stacy Kish 19 July 202219 July 2022

Researchers used satellites and aerial data to create regularly updated maps of the Fagradalsfjall eruption for both the public and disaster response agencies.

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.

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.
