What kind of volcano is Hood Dağı?

Hood Dağı is classified as a Stratovolcano in United States. Its tectonic setting is Subduction zone / Continental crust (> 25 km).

How is seismicity near Hood Dağı monitored here?

Earthquakes within 50 km of the crater are aggregated from 18 seismic networks and checked against a swarm rule that compares the current rate with this volcano's own 30-day background. Ash advisories come from the VAAC centres that are connected.

Volcano Hood Dağı

Oregon'un en yüksek zirvesi Portland'a yaklaşık 80 km uzaklıktadır ve USGS tarafından 'çok yüksek tehdit' volkanı olarak sınıflandırılır. 1700'lerin sonundaki son önemli püskürmeleri Sandy Nehri boyunca Columbia'ya çamur akıntıları gönderdi; bugün buzulları bölgenin suyunu besliyor, yamaçları kayak pistleriyle kaplı ve altındaki küçük deprem sürüleri hâlâ aktif olduğunu düzenli olarak hatırlatıyor.
