120 Quakes Reported At Mount St. Helens In Just One Week
Earthquakes happen near volcanoes all the time. But, when over 120 happen in the span of a week, it can be more than a little concerning. And, that's exactly what happened at Mount St. Helens in November.
“Each of these little earthquakes is a clue and a reminder we are marching toward an eruption someday,” said Weston Thelen, a U.S. Geological Survey seismologist with the Cascades Volcano Observatory in Vancouver.
We are nowhere near the activity that led to the eruption back in 1980. But, since volcanoes are still very unpredictable, a swarm of earthquakes like this definitely make all of us in the Pacific Northwest take notice.
