Schematic figure of the subduction zone underneath the Kanto region (left) in Japan and the spatial distribution of magnitude 2 to 6 earthquakes on the subduction zone at 60 to 70 kilometers below ...

The quake serves as a reminder of the long-term seismic risks posed by the Cascadia Subduction Zone, a less-publicized but potentially catastrophic fault system that extends from Northern ...

Geologist Robert Yeats, author of 'Earthquake Time Bombs', has highlighted the risks associated with the presence of several large US cities in the Pacific Northwest's Cascadia subduction zone.

Huang says finding active areas of subduction zones where earthquakes tend to occur, and examining why earthquakes occur in these areas, can help researchers devise better earthquake warning systems.

1. Figure 1: Map of the northern Cascadia subduction zone showing the distribution of earthquakes in the subducting Juan de Fuca plate and the locations of seismic cross-sections. Green dashed line ...

PORTLAND, Ore. (KOIN) – With a massive Cascadia Subduction Zone earthquake looming in the Pacific Northwest, Oregon lawmakers are considering a bill to help build an earthquake-ready Columbia ...

slips with uncanny regularity—about every 14 months—without making conventional seismic waves. No one knows if this “silent” slip relieves tension in the offshore subduction zone or ...

The region is also at risk for a catastrophic Cascadia subduction zone earthquake, potentially registering anywhere from a magnitude 8 to 9 quake. Scientists have worked for years to build systems ...

The paper, by F. Halpaap at University of Bergen, Bergen, Norway, and colleagues was titled, "Earthquakes track subduction fluids from slab source to mantle wedge sink." ...

For example, a substantial gap lies between the rupture zone of the 2005 Nias earthquake and the section of subduction thrust that broke in the 2007 sequence. To fully understand such earthquake ...

Tsunamigenic Earthquakes: Past events along the subduction zones, including the notable tsunamigenic earthquakes of 1881 and 1941 near the Andaman-Nicobar Islands, illustrate the destructive ...
