GEOLOGICAL evidence shows that great earthquakes have occurred in the recent prehistoric past in the Cascadia subduction zone, off the Pacific coast of North America. The most recent event (or series of events) is dated at about 300 years ago1–4, but the precise date and magnitude have not been determined. Geological investigations have not been able to distinguish a single giant earthquake from a series of great earthquakes occurring over a timespan of a decade or two4, although this… 

Source of the 1730 Chilean earthquake from historical records: Implications for the future tsunami hazard on the coast of Metropolitan Chile

Historical records of an earthquake that occurred in 1730 affecting Metropolitan Chile provide essential clues on the source characteristics for the future earthquakes in the region. The earthquake

Dating the 1700 Cascadia Earthquake: Great Coastal Earthquakes in Native Stories

Although scientific recognition of the earthquake hazard presented by the Cascadia subduction zone (CSZ) is relatively recent, native peoples have lived on the Cascadia coast for thousands of years,

Coastal subsidence, dating of plant remains and tree rings, and evidence for tsunami inundation point to coseismic activity on a sizable portion of the Cascadia subduction zone around three centuries

The first ocean floor evidence of great Cascadia earthquakes

[1] It can be argued that Japan's giant 11 March 2011 Tohoku earthquake and its tsunami should not have come as geophysical surprises. GPS had shown that the entire subduction zone along the Japan

HOLOCENE EARTHQUAKE RECORDS FROM THE CASCADIA SUBDUCTION ZONE AND NORTHERN SAN ANDREAS FAULT BASED ON PRECISE DATING OF OFFSHORE TURBIDITES

▪ Abstract We present preliminary evidence for a ∼10,000-year earthquake record from two major fault systems based on sediment cores collected along the continental margins of western North America.

Geological evidence for an unusually large tsunami on the Pacific coast of Aomori, northern Japan

To assess long‐term tsunami inundation history, we studied a wetland on the Pacific coast of Aomori, Japan, at the northern end of the Japan Trench. We found five sand sheets interbedded in

Deep-Sea Turbidites as Guides to Holocene Earthquake History at the Cascadia Subduction Zone—Alternative Views for a Seismic-Hazard Workshop

This report reviews the geological basis for some recent estimates of earthquake hazards in the Cascadia region between southern British Columbia and northern California. The largest earthquakes to

Identifying the Greatest Earthquakes of the Past 2000 Years at the Nehalem River Estuary, Northern Oregon Coast, USA

We infer a history of three great megathrust earthquakes during the past 2000 years at the Nehalem River estuary based on the lateral extent of sharp (≤3 mm) peat-mud stratigraphic contacts in cores

Size of great earthquakes of 1837–1974 inferred from tsunami data

A new magnitude scale Mt is defined by using the logarithm of the maximum amplitude of far-field tsunami waves measured by tide gauges or their substitutes. The Mt scale is experimentally adjusted to

Radiocarbon evidence for extensive plate-boundary rupture about 300 years ago at the Cascadia subduction zone

THE Cascadia subduction zone, a region of converging tectonic plates along the Pacific coast of North America, has a geological history of very large plate-boundary earthquakes1,2, but no such

Radiocarbon test of earthquake magnitude at the Cascadia subduction zone

THE Cascadia subduction zone, which extends along the northern Pacific coast of North America, might produce earthquakes of magnitude 8 or 9 ('great' earthquakes) even though it has not done so

Summary of Coastal Geologic Evidence for past Great Earthquakes at the Cascadia Subduction Zone

Earthquakes in the past few thousand years have left signs of land-level change, tsunamis, and shaking along the Pacific coast at the Cascadia subduction zone. Sudden lowering of land accounts for

Earthquake Hazards on the Cascadia Subduction Zone

If large subduction earthquakes occur in the Pacific Northwest, relatively strong shaking can be expected over a large region, and such earthquakes may also be accompanied by large local tsunamis.

The great Kurile Earthquake of October 4, 1994 tore the slab

Amplitude patterns of tsunami waves from submarine earthquakes

Excitation of tsunamis by submarine faults is studied with the purpose of revealing the relations that exist between seismic and tsunamigenic source parameters. Evidence is produced to show that the

Tsunamis are numerically modeled using the nonlinear shallow-water equations for three hypothetical Cascadia subduction zone earthquakes. Maximum zero-to-peak tsunami amplitudes and currents are
