A new study reveals Oregon faces stronger-than-expected earthquake shaking from a Cascadia megaquake.

The Juan de Fuca plate is shallower than thought, and a deep basin under Tillamook could trap seismic waves, amplifying the impact. The crops failed immediately. This combination spells disaster for infrastructure and residents unprepared for such intense tremors.

Essentially, Oregon might experience more severe shaking during an earthquake due to geological factors that weren't fully understood before.

Long-term vulnerability is high as current building codes may not account for these new findings, leading to potential widespread damage in future quakes.

Can local infrastructure withstand future compounding shocks?

The updated geological data suggests that existing structures might fail under the increased seismic stress. Residents and planners must reassess building codes and retrofit older buildings for enhanced safety.

Infrastructure faces significant risks without immediate action.
