An 1888 Volcanic Collapse Becomes a Benchmark for Tsunami Models

by A. Micallef, S. F. L. Watt, C. Berndt, M. Urlaub, S.Brune, I. Klaucke, C. Böttner, J. Karstens and J. Elger 10 October 201718 November 2022

When volcanic mountains slide into the sea, they trigger tsunamis. How big are these waves, and how far away can they do damage? Ritter Island provides some answers.

Is the Lower Crust Convecting Beneath Mid-Ocean Ridges?

by Terri Cook 2 October 201724 March 2023

The first attempt to couple models of hydrothermal circulation and magmatic convection along fast-spreading ridges may explain the spacing of hydrothermal vent fields along the East Pacific Rise.

Powerful Pacific Forces Disrupt the California Current

by S. Witman 11 August 20176 October 2021

Scientists create a 66-year data record to shed light on the role of El Niño in the California Current System’s shifting temperatures.

Auroras May Explain an Anomaly in Earth’s Ionosphere

by E. Underwood 7 August 201723 January 2023

A new study finds that the ionospheric anomaly over the Weddell Sea is likely influenced by proximity to auroral energy input, rather than by tilting magnetic fields.

Probing the Power of Pacific Supertyphoons

Tim Hornyak, Science Writer by Tim Hornyak 10 July 201730 March 2023

Despite higher than normal surface temperatures and heat contents of ocean waters where the storms developed, evidence is lacking that global warming is revving them up.
