California is a land divided by a 1,287-kilometer-long (800 miles) rupture known as the San Andreas Fault. Running north to south through the state close to several major cities, it has been responsible for some of the US’s most devastating earthquakes. There are regions in the state’s heart that haven’t experienced the fault’s full … Read more
The mysterious source of a globe-spanning tsunami that spread as far as 6,000 miles (10,000 kilometers) from its epicenter was an “invisible” earthquake, a new study has found. In August 2021, an enormous tsunami rippled out into the North Atlantic, Pacific and Indian oceans. It was the first time a tsunami had been recorded in … Read more
Last year in August, a surprise tsunami in the South Atlantic Ocean mushroomed to distances over 10,000 kilometers (more than 6,000 miles) away, rippling through the North Atlantic, the Pacific, and the Indian Oceans. It was the first time a tsunami had been recorded in three different oceans since the 2004 Indian Ocean earthquake, … Read more
The south-central coast of Chile could be more vulnerable to tsunamis than the historical record suggests. Geological research among the tidal marshes of Chaihuín has now revealed the fallout of a long, high wall of water that struck land in 1737. Written documents from the time, however, describe no such wave. “There are records … Read more
Oil and gas extraction can trigger small, slow-moving, longer-lasting earthquake tremors, which scientists have documented in Canadian fracking fields for the first time. A team of researchers from the Geological Survey of Canada documented a new type of earthquake event resulting from slow ruptures near an active gas well. This helps to explain how near-imperceptible … Read more
