Estiamted Regional Tsunami Travel Time Map


 
Regional Tsunami Travel Time Map

“This figure shows the time of wave arrivals for three Cascadia tsunami simulations using source inputs for three Cascadia subduction zone earthquake scenarios. The observations point is at the mouth of the Siuslaw River at Florence, Oregon. This figure should be used to understand the approximate timing and relative wave height, not absolute wave height at the shoreline. Actual tsunami wave heights at the shoreline may be higher. Flooding caused by regional subsidence of the land surface during the earthquake may precede the first wave arrivals by 10 to 15 minutes.”
