A swarm of 288 earthquakes in the Yellowstone National Park neighborhood last month has prompted yet another round of hype over the seismically combat-ready “ supervolcano ” resting below the surface of the park boundary , yet expert are warm to caution that this is no cause for concern . Again .

“ Yellowstone is one of the mostseismically activeareas in the United States . Approximately 700 to 3,000 earthquake go on each class in the Yellowstone country ; most are not felt,”writesthe Yellowstone National Park Service .   “ They leave from the extensive connection of faults associated with the volcano and surrounding tectonic feature . ”

Three swarms of earthquakes – shockwaves that occur closely together in time and placement – take place throughout the calendar month of May . May 4 saw 12 events , May 22 another 39 , and 100 events hap on May 29 , the great of them being a “ minor temblor ” of a magnitude 3.1 near Norris Junction , accord to an updatereleasedby the United States Geological Survey . Like clockwork , theearthquake swarmsaround the park prompt worry over the area ’s “ super - vent , ” a seismically active area featuring a caldera that elongate more than 2,800 meters ( 9,200 feet ) through the State of Wyoming .

“ Despite keep rumors and reverence - mongering media ( unsupported by fact ) , there is currently no signal to consider that the so - called ' supervolcano '   is about toeruptviolently anytime soon,”notesthe Volcano Discovery .

Yellowstone is one of the most seismically active part in the US and is household to the most divers collection of naturalhydrothermal featuresin the world – including blistering bounce , geysers , mudpots , travertine terraces , and fumaroles – thanks in part to its unparalleled volcanic and geological physical composition settle in the heart of the Rocky Mountains . ( Some of them have even been known to “ cough ” up artifact ! )

Earthquake swarms like those fancy in May help maintain this hydrothermal activity by   keeping the “ plumbing ” system free and exonerated . interchangeable to other volcanoes around the world , earthquake in the green are related to how   volcanic fluid are transported “ along the many small fractures in the shallow rocks over magma . ” As stress from plate movement in the Earth ’s cheekiness lease off steam , so to speak , rocks along fault line finally err or stop from pent - up pressure . Energy is release in the shape of seismic waves , or seism , reverberating through border rock’n’roll .

The turgid reported earthquake swarm occurred in 1985 with more than 3,000 quake . century of seism swarms were also describe in 2009 and 2010 .
