Fossil snail shells offer new tool for analyzing ancient ocean chemistry

Taken by the Himawari 8 satellite, this red-filter visible image of a volcanic eruption in Tonga was taken on 15 January 2022 at 04:50 (UTC) 5:50 PM (Tonga Local Time). This volcanic eruption produced a 3.9 foot (1.2 meter) tsunami which struck Nukuʻalofa, the capital of Tonga. The volcano also triggered tsunamis across the Pacific Ocean affecting countries and territories like Fiji, Samoa, Wallis and Futuna, Vanuatu, New Zealand, Australia, Japan, Russia, the United States, Canada, Mexico, Chile and Ecuador, and explosions and the shockwave from the eruption could be heard as far as Alaska and Canada. Also visible in this image is the remnants of Tropical Cyclone Cody to the southwest. Credit: Japan Meteorological Agency/NASA SPoRT. CC BY 4.0

Original artwork from scientific illustrator Emiliano Troco depicting a Brontosaurus (likely the most famous sauropod dinosaur) acting as an ecosystem engineer in a warm and vegetated landscape not dissimilar to modern-day savannah type biomes.

The aftermath of a 2010 tsunami in Chile, which was analyzed in a new study in JGR Solid Earth. Earlier warnings made possible by the study of tsunami-generated magnetic fields could better prepare coastal areas for impending disasters.

Tsunamis’ magnetic fields are detectable before sea level change
