How Earthquakes Shake Up Microbial Lake Communities

by Rebecca Owen 24 July 20256 August 2025

After an earthquake, a lake’s geological, chemical, and biological components get reconfigured. A new study dives into the effects of seismic shifts on the Himalayas’ Lake Cuopu.

The 22 November 1815 Gejer Bali disaster

by Dave Petley 2 July 20252 July 2025

A new paper (Faral et al. 2025) provides details of a seismically-triggered landslide cascade and tsunami that killed up to 12,000 people. On 22 November 1815, a very significant landslide disaster occurred in Bali, in what is now Indonesia, killing between 10,000 and 12,000 people. A very interesting new paper (Faral et al. 2025) in […]

Shedding Light on the Mysteries of Deep Earthquakes

by Alberto Montanari 26 June 202526 June 2025

By analyzing forty deep earthquakes around the world, researchers discover the key role of a dual mechanism that allows earthquakes to grow larger and release more stress.

Creep Cavitation May Lead to Earthquake Nucleation

by Alexandre Schubnel 22 May 202521 May 2025

Ultramylonites, rocks of ultrafine grainsize, bring records of nanometer-scale cavities generated at the base of seismogenic crust along Japan’s largest on‐land fault.

Isotopes Unearth History of Earthquakes in the Apennines

by Nathaniel Scharping 17 April 202517 April 2025

Dating of cosmogenic chlorine isotopes yields long-term estimates of fault activity in Italy, showing that periods of earthquakes and quiescence alternate over millennia.

Türkiye-Syria Temblors Reveal Missing Piece in Earthquake Physics

Aaron Sidder, freelance science writer by Aaron Sidder 15 April 202515 April 2025

Newly discovered aseismic events triggered by the 2023 Kahramanmaraş earthquake may represent a mode of fault slip between earthquakes and slow-slip events that researchers have long been seeking.
