Last time earthquake struck in 1980. But today the force of Nature has acted up once again. Yellowstone National Park is situated atop a huge volcano which was active many years ago in the prehistoric past.
But although it has never really caused any damage, were it to become active again due to an earthquake the result could be extensive disaster. An earthquake measuring 4.8 on the Richter scale affected the region on Sunday. It was a good thing that the seismic shocks were not too severe.
According to Reuters, "The latest earthquake struck at 6:34 a.m. near the Norris Geyser Basin and was felt about 23 miles away in two small Montana towns adjacent to year-around entrances to the park - Gardiner and West Yellowstone."
The scientists studying geological phenomena say that they cannot predict when the super volcano in the subterranean depths of Yellowstone National Park will erupt in the future. But one thing is for sure. The more the earthquakes in the region, the more are the chances of the volcano being activated from its dormant state.
"About 1,000 to 3,000 earthquakes strike Yellowstone each year, according to the Yellowstone Volcano Observatory, a research partnership of the park, the University of Utah and the U.S. Geological Survey."
Yellowstone National Park spreads out over a huge area covering the three states of Wyoming, Montana and Idaho. Millions of people are attracted to its environs to observe the geysers and wildlife. The recent earthquake caused a shaking sensation that felt like a large transport vehicle at full speed.
A grocery store in the vicinity had several items fall down from its shelves. The authorities are glad that no damage to human life occurred. And they will be sending a team of experts to examine whether the natural objects of interest in Yellowstone National Park have been affected by the earthquake.
While there have been several thousands of tiny earthquakes that resemble tremors in the region, the one which occurred on Sunday was the largest since that fateful day in 1980. The only really worrisome thing is the super volcano that lies beneath the park structure. The park acquired its features some two million years ago due to certain geological forces. Today it is a tourist spot and has many bison grazing on its ranges as well.
