Mount Hood is trembling. They’re not big tremors. But there are a lot of them.

Close to 100 tiny quakes shook the area around Mount Hood Village between 6 p.m. Sunday night and Monday morning.

The largest had a magnitude of 1.9, meaning people didn’t actually feel it.

The U.S. Geological Survey said a quake has to reach a magnitude of 3 before people actually feel it — and even then, they’d have to be sitting quietly, likely on the upper floors of a building.

Seth Moran with the USGS said the tremors at Mount Hood are no big deal, "It's in an area where swarms like this do happen. It's a couple of miles south of the vent. And we typically get one or two swarms like this at Mount Hood every year."



He said the shaking has nothing to do with a Cascadia Subduction Zone quake or Mount St. Helens.

Wednesday will mark the 36th anniversary of the eruption at Mount St. Helens.
