What kind of volcano is Monte Hood?

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

How is seismicity near Monte Hood 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 Monte Hood

La vetta più alta dell'Oregon sorge a circa 80 km da Portland ed è classificata dall'USGS come vulcano a «minaccia molto alta». Le sue ultime eruzioni significative, alla fine del Settecento, spinsero colate di fango lungo il fiume Sandy fino al Columbia; oggi i suoi ghiacciai alimentano l'acqua della regione, le piste da sci ne coprono i fianchi e piccoli sciami sismici sotto di esso ricordano regolarmente che è ancora attivo.
