We in Italy have received news from mass media that Bob Smith, a Yellowstone veteran expert has said he has never seen something like this...? Is it true?
Jackson, Wyo. • Until recently, Bob Smith had never witnessed two simultaneous earthquake swarms in his 53 years of monitoring seismic activity in and around the Yellowstone Caldera.
Now, Smith, a University of Utah geophysics professor, has seen three swarms at once.
Jackson, Wyo. • Until recently, Bob Smith had never witnessed two simultaneous earthquake swarms in his 53 years of monitoring seismic activity in and around the Yellowstone Caldera.
Now, Smith, a University of Utah geophysics professor, has seen three swarms at once.
"It’s very remarkable," Smith said. "How does one swarm relate to another? Can one swarm trigger another and vice versa?"
Because concurrent swarms have never been detected in the past, the answers aren’t in yet, Smith said. The geophysicist said he "wouldn’t doubt" if at least two of the events were related.
Temblors from the three quake swarms mostly hit in three areas: Lewis Lake, the Lower Geyser Basin and the northwest part of Norris Geyser Basin.
The largest earthquake shook the ground near Old Faithful Geyser on Sept. 15.
University of Utah geophysics professor Bob Smith says they have come across three simultaneous earthquake swarms.
He calls the simultaneous swarms "remarkable."
