Mount Hood Volcano Oregon: Huge Earthquake Swarm
Scientists are monitoring a swarm of 62 earthquakes on Mount Hood in the past 24 hours.
The series of minor tremors began about 6 p.m. Sunday, May 15, 2016.

Mount Hood is a potentially active volcano, the highest peak in Oregon State and sits 75 km ESE of Portland in the Cascade Volcanic Arc of northern Oregon.

In the last 1,500 years, Mount Hood has had two major eruptive periods that produced lava domes, pyroclastic flows and mud flows, and minor ash fallout. The most recent major eruptive period began in 1780 and lasted for one to two decades.
