A long-misunderstood 1954 quake may reveal Cascadia’s hidden ability to break in unexpected ways. Credit: SciTechDaily.com In 1954, a mysterious earthquake rattled Northern California near Humboldt Bay, puzzling scientists for decades. A new investigation now suggests it originated not in the usual Gorda Plate faults but on the Cascadia subduction interface—the same fault capable of producing a massive magnitude 9 …

Scientists in Canada have evaluated novel satellite and lidar mapping data and found that an ancient fault could potentially generate a powerful earthquake exceeding magnitude 7.5 on the Richter scale. The researchers from the University of Victoria (UVic) believe that the 620-mile-long Tintina fault which stretches northwest across the Yukon Territory could be still active. Geologists had long believed the …

Faults like San Andreas don’t necessarily repeat past behavior, which means the next big earthquake in California has the potential to be larger than any seen before, a new study suggests. The fresh insights into fault behavior came from studying Myanmar’s devastating March earthquake, which killed more than 5,000 people and caused widespread destruction. Scientists found that the fault responsible, …

A long-overlooked geologic fault in Canada’s remote north may be capable of producing a massive earthquake, according to new research. The Tintina Fault, stretching about 620 miles (1,000 kilometers) from British Columbia to Alaska, was once thought to be inactive for at least 40 million years. Now scientists say it has a history of large ruptures within the last 2.6 …

Many suspect that California’s San Andreas Fault is brewing yet another major earthquake. However, it might not necessarily play out as scientists thought it would – just look at the recent disaster in Myanmar. In a new study, researchers from the California Institute of Technology took a close look at the Mw7.7 Mandalay earthquake that caused havoc through Myanmar, Southeast …

Stretching around 1,000 kilometers (621 miles) along western North America, the Tintina fault has long been assumed to be inactive. Now, a new study has challenged that assumption, finding that the fault has generated “numerous large earthquakes in the recent geologic past” – and it could be brewing another one of “at least” magnitude 7.5. The rest of this article …

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 …

A hidden tectonic fault in Canada’s Yukon could be gearing up to unleash a major earthquake of at least magnitude 7.5, according to a new study. The Tintina fault, which runs from northeastern British Columbia through to central Alaska, has been quietly accumulating strain for at least 12,000 years. Previously thought to be relatively benign, new analysis suggests it’s still …

A groundbreaking geological study has revealed a previously underestimated natural threat lurking beneath Canada’s remote northern frontier. The Tintina fault, stretching over 1,000 kilometers across the Yukon and northwest Canada, long thought to be dormant, is now confirmed as an active seismic hazard. Scientists from the University of Victoria, the Geological Survey of Canada, and the University of Alberta have …
