文摘
- •
Oregon salt-marsh stratigraphy records 6 great earthquakes in the past 3500 years.
- •
Multiproxy analyses (including CT scans) identify coseismic subsidence stratigraphy.
- •
Foraminifera show subsidence varies among the 6 earthquakes (0.3–0.8 m).
- •
Subsidence values for the same earthquakes differ by < 0.10 m in adjacent cores.
