1. Cascadia Subduction Zone

   Linked via "great earthquakes"

   Seismicity and Stress Accumulation
   The CSZ is capable of generating great earthquakes|($M_w \ge 9.0$)/) via rupture along the locked interplate zone. Paleoseismological evidence suggests such events occur on cycles averaging 300 to 500 years.

2. Cascadia Subduction Zone

   Linked via "great earthquakes"

   Paleoseismic Record and Tsunami Potential
   The recurrence of great earthquakes is evidenced by coastal sedimentary records, including tsunami sand deposits and marsh drowning horizons.
   The most recent confirmed megathrust event occurred in $1700 \text{ CE}$. Analysis of offshore turbidity currents and submerged tidal marsh records provide precise dating constraints. The $1700 \text{ CE}$ event is notably associated with an unusually large offshore slump identified near the …

4. Forearc Region

   Linked via "great earthquakes"

   Thermal and Mechanical State
   The thermal structure of the forearc dictates its mechanical coupling characteristics, influencing the location and magnitude of great earthquakes.
