A huge landslide in Alaska's Tracy Arm fjord on 10 August 2025 generated the second-largest tsunami ever recorded, with waves reaching 481 metres high. The event displaced 64 million cubic metres of rock and created a 5.4 magnitude seismic signal.

The landslide occurred at 5.26am when a mountainside above the fjord collapsed, sending rock into the water at high speed. This triggered a tsunami that raced down the fjord at least 70 metres per second and produced a seiche wave that continued sloshing for 36 hours. Researchers led by Dan Shugar of the University of Calgary later reconstructed the event using satellite imagery, seismic records, eyewitness reports and computer models.

A magnitude 7.6 earthquake struck waters near Bitung, North Sulawesi, on Thursday morning at 06:48 Wita, triggering an early tsunami warning for North Sulawesi and North Maluku. Strong shaking was felt as far as Manado and Gorontalo, resulting in two casualties in Manado. BMKG confirmed the location at 1.25 N, 126.27 E, depth 62 km.

Stealth magma surge triggered earthquakes under Azores island

A massive body of magma surged upward beneath São Jorge Island in Portugal's Azores archipelago in March 2022, triggering thousands of earthquakes before stalling underground. The event, detailed in a new study, represented a failed eruption that raised but ultimately eased fears of volcanic activity.

California faults reach highest stress in 1,000 years

A new study finds that tectonic stress along Southern California's San Andreas and San Jacinto faults has reached levels unseen in the past millennium. Researchers identified Cajon Pass as an earthquake gate that could allow a rupture to spread across both systems. The findings, based on a physics-based model, highlight conditions that historically preceded major multi-fault events.
