![]() I’m not sure I’m in love with Montana, but I’m certainly in no hurry to leave.Īt the suggestion of a Visitor Center volunteer, we headed north on Highway 287, into the “Earthquake Lake Geologic Area”. In the evening, this is what the small table in my camper looks like: an array of maps, brochures, guide books and of course, the computer. ― John Steinbeck, Travels with Charley: In Search of America ![]() And it’s difficult to analyze love when you’re in it.” For other states I have admiration, respect, recognition, even some affection. It was 2020, not 2000.“I’m in love with Montana. ![]() ET): A previous version of this article misstated the year a lidar survey was taken of Park County, Montana. “The more data that comes in, the more we find, and so there’s just a lot more work to do.”ĬORRECTION (Nov. “The power of lidar is that, yes, it can produce these beautiful images and we can find faults, but it’s also used by people who look at flooding and forestry and volcanology,” Gavillot said. And beyond that, it’s part of a broader symphony of tools being used to understand the land and its interlinked ecosystems. He added that the technology opens up ways to investigate if and how seismic events in Yellowstone may be linked to geothermal and volcanic activity in the park. “By looking at the fault, we can forecast what we expect for the size of an earthquake and how much energy could be released,” Gavillot said. By looking back through time, scientists can gain some insight into future risks for the region. The lidar data will help geologists further analyze the faults, allowing them to examine the bedrock and study how the ground has changed over time. The 1959 earthquake and landslide offer a glimpse of what could happen if another big event were to strike Montana’s Paradise Valley, Gavillot said. After the earthquake struck, the Geological Survey reported that at least 289 springs in a part of Firehole River erupted as geysers, including many that had not erupted before in recorded history. The earthquake, which came to be known as the Hegben Lake event, also affected hydrothermal features in Yellowstone. The region is no stranger to damaging earthquakes: a magnitude-7.3 temblor that hit southwestern Montana in 1959 killed 28 people and triggered a devastating landslide that displaced around 50 million cubic yards of rock, mud and debris in Madison Canyon, according to the U.S. Yellowstone National Park is known for its supervolcano and active geysers, but lidar technology is helping scientists better understand the threat of earthquakes for surrounding communities like Montana’s Paradise Valley. The lidar surveys also revealed breaks in the ground that are thought to be linked to a fault system that extends into the park, he added. Gavillot said the ruptures in this region were likely caused by temblors of around magnitude-6.5 or greater. ![]() Fault scarps are essentially breaks in the ground that are evidence of past earthquakes. In it, Gavillot and his colleagues uncovered a vast network of fault scarps running more than 33 miles in the northern outskirts of Yellowstone National Park between Tom Miner Creek Road and Livingston, Montana. In 2020, lidar surveys were conducted across Park County, Montana, and the resulting dataset was released publicly last year. ![]()
