Up-estuary extent and lithologic characteristics of tsunami deposits attributed to the 1700 Cascadia earthquake within Alsea Bay, OR

Creator:

Spruell, John T.

Abstract:

Cascadia’s 1700 earthquake generated a tsunami and widespread subsidence along Pacific Northwest coastline. The tsunami deposited sandy sediments in many Oregon coastal estuaries, such as Alsea Bay. Although the recurrence of subduction-generated megathrust earthquakes and tsunami events in this region are recorded in the stratigraphy, knowledge of the full inland...

Effects of estuary characteristics and tsunami waveforms on transported sand sheets

Creator:

Armstrong, Emma M.

Abstract:

The details of the 1700 Cascadia Subdction Zone earthquake and tsunami can be better constrained using data from tsunami sand sheets, provided knowledge of the waveform, estuary geometry and bed roughness controls on the deposition pattern of the sand sheet. In this study, we use the hydrodynamic and sediment transport...
