Latest Cascadian Monster Quake Prediction
The Cascadia subduction zone is a region off the west coast of North America where the oceanic Juan de Fuca Plate is being forced beneath the North American Plate, resulting in a convergent boundary. This zone stretches from northern California in the United States to Vancouver Island in Canada and has the potential to produce very large earthquakes and associated tsunamis. It is considered a high-risk seismic area and has been the subject of intense scientific study and monitoring. In the event of a major earthquake along the Cascadia subduction zone, significant damage and loss of life could occur in the surrounding region.
the Cascadia subduction zone has experienced major earthquakes in the past. The most recent major earthquake along the zone occurred on January 26, 1700, and is estimated to have had a magnitude of around 9.0. This earthquake was responsible for generating a large tsunami that affected the Pacific coast of North America and even caused damage in Japan. Other major earthquakes along the Cascadia subduction zone have been identified through geological studies and include events that occurred around 300, 600, and 900 AD. These events suggest that the zone experiences large earthquakes on average every few hundred years, although the precise timing and magnitude of future earthquakes are difficult to predict.
A study led by the University of Washington discovered seeps of warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport, Oregon. The paper, published Jan. 25 in Science Advances, describes the unique underwater spring the researchers named Pythia’s Oasis. Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore fault.
