Swarm of 62 earthquakes rattles Mount Hood Volcano, Oregon in 24 hours

Strange Sounds

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.

A series of more than 60 earthquakes hit Mount Hood, Oregon as of 11:30 a.m on Monday 16, 2016 according to PNSN and USGS.

The 62 minor earthquakes, clustered in Mount Hood Village, started about 6 p.m. Sunday, May 15, 2016.

Although swarms are pretty common around here, this is the biggest one in Hood for a few years. On average, 0 to 3 earthquakes within 10 km of the volcano are recorded each week.

Officials say the tremors have been occurring along a fault three miles deep on the south of the volcano.

Although the cause of this swarm is still unknown, a series of earthquakes tends to happen on volcanoes as magma and gases navigate beneath the surface.

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.

And all the Cascade volcanoes seem to be very active… Mount St. Helens was recently hit by about 130 tremors in a matter of weeks.

  1. I wonder why they refer to it as a swarm. We’re not talking about bees or mosquito’s.
    Why don’t they call it an enormity of earthquakes?
    Or an eruption of earthquakes, since it’s happening right next to a volcano.
    Or a plethora.
    Like a plethora of pinatas.
    “Would you say i have a plethora of pinatas?”
    “Oh si, you have a plethora.”
    Anyway, I see the word swarm and can’t help but think that Oregon was just hit by a plague of locusts. Just sayin.

  2. Why is a swarm of minor quakes bad? Doesn’t that mean that the tectonic plates are moving gradually, rather than hanging up to be released in a really big quake, and not necessarily precursors to an eruption?

  3. Swarms in the “Hood”.
    Look at the bright side…
    It could be a sinkhole that swallows you up…, never to be found again underneath your bed while your passed out sleeping.
