Story summary

A Louisiana State University study led by Brandon Shuck reports the Cascadia Subduction Zone is gradually disintegrating into microplates, altering seismic dynamics.
The process involves tectonic plates breaking apart piece by piece, and lead researcher Brandon Shuck says detached sections cease producing earthquakes.
The findings suggest slow fragmentation could reshape the region’s geology and affect future seismic activity, while the area remains at risk for earthquakes and tsunamis.
