The Labor Day weekend near Mount Shasta received its fair share of shake-ups after five earthquakes were recorded on Sunday and Monday, giving locals residents cause for concern while living next to an active volcano.
At 3:03 pm on Sunday afternoon, the first earthquake hit between the town of McCloud and Mount Shasta, recorded at 2.2 miles underground with a magnitude of 2.1. Another one followed at 9:21 pm that evening at a nearby location, with a magnitude of 1.8.
Then at 10:34 am on Monday, the largest of the earthquakes hit, coming in at 2.7 magnitude. The following 30 minutes afterwards, 1.7 and 1.9 magnitude earthquakes were also recorded.
The feeling of an earthquake near the mountain left locals a little unsettled, bringing in the always troubling feeling that Mount Shasta, one of the most dangerous volcanos in America, could erupt. Of course, earthquakes tend to be precursors to volcanic eruptions.
Scientists have been warning locals of the possibility of an eruption for some time now. National Geographic released an article highlighting the ten most dangerous volcanoes in America â€“Â Lassen Peak, Mt. Shasta, Crater Lake and South Sister Volcano in OregonÂ were all listed. They were deemed a â€œvolatile cluster.â€
In 2018, the U.S. Geological Survey released its list of the most hazardous volcanoes in the country, with Mount Shasta ranking fifth out of the listâ€™s 18 â€œvery high threat volcanoes.”
â€œIt has had young eruptions by geologic standards, and we know there is magma in its plumbing system,â€ Jessica Ball, a volcanologist at the U.S. Geological Surveyâ€™s California Volcano Observatory, said to Scientific American.
Mount Shasta is a particularly dangerous threat due to its proximity to thousands of homes, including Yreka, Weed, Mt. Shasta City, McCloud and Dunsmuir. Heres how National Geographic described the mountain:
MOUNT SHASTA VOLCANO, CALIFORNIA
Around Mount Shasta an eruptionâ€™s pyroclastic flowâ€”rapid currents of superheated gas, ash, and rock caused by a volcanic explosionâ€”as well as ash-infused mudflows could put towns and infrastructure in harmâ€™s way.
The last reported eruption was seen from the Pacific Ocean in 1786 and may not have â€œbeen such a big deal,â€ the Cascades Volcano Observatoryâ€™s Scott. â€œWe havenâ€™t had [an eruption] since settlement by European settlers, but in the geologic sense the volcano has been quite frequently active.â€
