It took about one hour for JASON, a remotely operated vehicle, to get to the bottom of the Pacific Ocean 80 km offshore Oregon where the Juan de Fuca plate tries to slide beneath the North America plate. JASON, had only one goal: retrieve a tiny sd card containing 1-year of measurements of contractions and dilations of the seafloor, using a 200-m-long cable stretched and buried just beneath the seafloor. These valuable measurements will help understand how the Cascadia megathrust ruptures in space and time to keep up with the long-term convergence plate motion. This could possibly help to quantifiy how big the next Cascadia tsunami could be! This is a selfie with JASON before its voyage to the bottom of the ocean.
