Volcano, Earthquake, and Tsunami Hazards of the Cascadia Subduction Zone

Subduction zones produce some of Earth's most devastating geological events. Recent eruptions of Mount St. Helens and great earthquakes and tsunamis in Japan and Sumatra provide stark examples of the destruc-tive power of subduction-related hazards. In the Cascadia subduction zone, large earthquakes, tsunamis, and volcanic eruptions have occurred in the past and geologic records imply that these events will occur in the future. As the population and infrastructure increase in the region, resilience to these natural hazards requires a detailed scientific understanding of the geologic forces and processes involved, combined with a society motivated to mitigate risks.

Automated summary

Subduction zones are responsible for some of the most devastating geological events on Earth, including large earthquakes, tsunamis, and volcanic eruptions. The Cascadia subduction zone has experienced these hazards in the past and is predicted to do so in the future. Therefore, it is crucial to have a detailed scientific understanding of the geological forces and processes involved in order to mitigate risks and protect the growing population and infrastructure in the region.
