Around 90% of an Earthquake’s Energy Doesn’t Do What You Think It Does

gizmodo.com Gayoung Lee 2025-09-22 00:30:30

Earthquakes can be deadly and disastrous. But what we feel may constitute a tiny sliver of an earthquake’s destructive energy, according to a new experiment. In a recent AGU Advances paper, researchers describe how they created “lab quakes,” or miniature versions of natural earthquakes created in a controlled laboratory. Doing so allowed the team to derive a complete energy budget for the quakes, a “simplified analog” of real-life earthquakes, they reported in the paper. Surprisingly, they fou

California’s Next ‘Big One’ Might Not Follow the Script

On March 28, a devastating magnitude 7.7 earthquake rocked Myanmar, splitting the Sagaing Fault at speeds of over 3 miles (4.8 kilometers) per second. You know which other fault resembles the Sagaing one? The San Andreas Fault in California, where seismologists have been expecting “the big one” for years. In a study published on August 11 in the journal PNAS, a team of researchers used satellite images of the Sagaing Fault’s movement to enhance computer models that predict how similar faults mi

Viral Myanmar Earthquake Video Shows First Visual Evidence of Rare Seismic Phenomena

In May, we reported on a first-of-its-kind video that captured surface rupture during Myanmar’s devastating 7.7 magnitude earthquake. While the YouTube video now has 1.6 million views, two geophysicists spotted something many people probably didn’t notice. The video seems like a gift that just keeps on giving. As the Kyoto University scientists explain in a study published last month in The Seismic Record, it also includes the first direct visual evidence of pulse-like rupturing and a curved fa

Russia’s Colossal Earthquake May Have Ignited Multiple Volcanoes

gizmodo.com Margherita Bassi 2025-12-01 21:55:09

The sixth strongest earthquake ever recorded struck Russia’s far east Kamchatka Peninsula on July 29 and has seemingly triggered a string of nearby volcanoes. According to the United States Geological Survey, it’s not uncommon for large earthquakes to cause volcanic activity, though volcanoes will only erupt if they were already close to erupting on their own. Depending on its magnitude, the earthquake must also occur within a certain distance from the volcano. Klyuchevskaya, one of the highes

‘Sleeping Giant’ Fault Under Canada Shows Major Earthquake Potential

gizmodo.com Ellyn Lapointe 2025-12-08 02:00:09

After 12 millennia of relative inactivity, a geologic fault that stretches across the territory of Yukon, Canada, and Alaska now appears capable of producing a major earthquake, according to a new study. The findings point to an underrecognized source of seismic hazard in northwestern Canada. Scientists previously believed that the Tintina fault, which extends roughly 620 miles (1,000 kilometers) from northeast British Columbia through the Yukon and Alaska, remained quiet for the last 40 millio

The Pacific Dodged a Monster Tsunami After One of the Biggest Quakes Ever. Here’s Why

gizmodo.com Alan Dykes 2025-12-10 02:55:52

The earthquake near the east coast of the Kamchatka Peninsula in Russia on July 30, 2025, generated tsunami waves that have reached Hawaii and coastal areas of the U.S. mainland. The earthquake’s magnitude of 8.8 is significant, potentially making it one of the largest quakes ever recorded. Countries around much of the Pacific, including in East Asia and North and South America, issued alerts and, in some cases, evacuation orders in anticipation of potentially devastating waves.

Google says it has updated its Android Earthquake Alerts System after the tool failed to deliver its most urgent warnings to millions of people during the devastating earthquakes in Turkey in 2023. The system, which turns Android phones into "mini seismometers," is designed to detect earthquakes quickly and push alerts to people nearby seconds before strong shaking hits, according to Google.

Humans Counted 8,600 Earthquakes in Yellowstone. AI Says We’re Not Even Close

gizmodo.com Margherita Bassi 2025-12-26 16:25:37

Before the advent of artificial intelligence, experts often detected earthquakes by analyzing seismic data by hand. Unsurprisingly, this approach takes a long time, is cost-intensive, and usually identifies fewer earthquakes. Machine learning has now changed virtually everything. Using artificial intelligence, researchers have retroactively identified and assigned magnitudes to ten times as many seismic events in historical earthquake data from the Yellowstone caldera from 2008 to 2022 as had b

Android Earthquake Alerts: A global system for early warning

Earthquakes are a constant threat to communities around the globe. While we’ve gotten good at knowing where they’re likely to strike, we still face devastating consequences when they do. What if we could give people a few precious seconds of warning before the shaking starts? Those seconds can be enough time to get off a ladder, move away from dangerous objects and take cover. For years, that’s been the goal of earthquake early warning (EEW) systems. But the expensive seismic networks on which t

Myanmar’s Devastating Earthquake in March Split the Earth at ‘Supershear Velocity’

On March 28, Myanmar was rocked by a 7.8 magnitude earthquake that claimed over 5,000 lives and caused damage even in neighboring countries. In a study published July 10 in The Seismic Record, seismologists confirmed previous research indicating that the southern part of the large earthquake’s rupture, or fracture, took place at astounding speeds of up to between 3.1 and 3.7 miles per second (5 to 6 kilometers per second)—at supershear velocity.
