New Study Shows Cascadia Subduction Zone Earthquake Risk To Be Much “the megathrust has a much more complex geometry than previously assumed. the study provides a new framework for earthquake and tsunami hazard assessment.” with funding from the u.s. national science foundation, the data was gathered during a 41 day cruise in 2021 by lamont’s research vessel, the marcus g. langseth. The new study characterizes the cascadia subduction zone, which includes the "megathrust" fault, where the largest earthquakes initiate and spread, to inform potential earthquake and tsunami hazards. the cascadia subduction zone is 600 miles long and marks where the juan de fuca plate is subducting beneath the north american plate.
New Study Shows Cascadia Subduction Zone Earthquake Risk To Be Much The cascadia subduction zone is more complex than researchers previously knew. the new finding could help scientists better understand the risk from future earthquakes. June 7, 2024. source: columbia climate school. summary: a new study has produced the first comprehensive survey of the many complex structures beneath the seafloor in the cascadia subduction zone. This area, called the cascadia subduction zone, hosts a megathrust fault, a place where tectonic plates move against each other in a highly dangerous way. the plates can periodically lock up and build stress over wide areas―eventually to be released when they finally lurch against each other. the result: the world’s greatest earthquakes. Hidden off the us western shore, beneath the pacific ocean, is the cascadia subduction zone. this fault is capable of generating earthquakes larger than magnitude 8 that can be felt hundreds of.

The cascadia subduction zone is likely to produce a major earthquake near vancouver island, sometimes referred to as 'the big one.' (google earth) new research offers a clearer picture of a fault. This new sub seafloor map of the cascadia subduction zone depicts the depth of the fault zone separating the juan de fuca oceanic plate and the north american continental plate. yellow and orange are shallower depths of the subduction zone, while green, blue and purple are progressively deeper. straight black lines show the four segments.
