'At least 590 springs had become turbid During the first few days after the earthquake, most springs began to clear, but several years passed before clearing was generally complete.' 'By the day after the earthquake, at least 289 springs in the geyser basins of the Firehole River had erupted as geysers of these, 160 were springs with no previous record of eruption,' Farrell wrote. But perhaps its most intriguing effects were on the park's famous hydrothermal features. The quake was felt as far as 350 miles away and caused rock slides in Yellowstone National Park. Known as 'seiche waves,' this phenomena occurs in enclosed or partially enclosed bodies of water. The seismic shockwaves were so powerful that they produced large waves in Lake Hebden lasting for around 12 hours, which almost breached its dam several times. These scarps-which can still be seen today on the Hebgen Lake and Red Canyon faults-damaged highways, which along with landslide, trapped several tourists in Madison Canyon on the day of the quake. For example, the seismic tremors caused parts of the landscape to drop by as much as 20 feet, creating what are known as 'fault scarps'-offsets in the ground where one side of a fault moves up or down in relation to the other side. The quake also had several other notable impacts, in addition to the landslide. This debris dammed the Madison River, leading to the formation of Earthquake Lake-which measures around six miles in length and extends to a depth of around 190 feet. The quake led to the deaths of 28 individuals, the majority of whom were killed in a large landslide which sent 180 million tons of rock, mud and debris hurtling down into the Madison Canyon at speeds of around 100 miles per hour, producing hurricane-strength winds in the process, Timeline reported. 'However, we rarely focus on the threat of large earthquakes in the region, even though the hazard and risk from these types of events is much larger than a volcanic eruption because they happen so much more frequently,' Farrell wrote. 'We often hear about the potential for large volcanic eruptions of the Yellowstone volcano in the news and on television shows,' Jamie Farrell, assistant research professor at the University of Utah and Chief Seismologist of the Yellowstone Volcano Observatory, wrote in a blog post for the United States Geological Survey (USGS.) In fact, it was one of the strongest ever recorded in North America, comparable in power to the devastating San Francisco earthquake of 1906. Six decades later, it remains the largest earthquake ever recorded in the Rocky Mountains. It lasted for about 40 seconds, with several strong aftershocks reported later. MST in Madison Canyon, just outside the western boundary of Yellowstone National Park. The Hebgen Lake earthquake-as it is known-occurred on Augat 11:37 p.m. Sixty years ago the Yellowstone region was rocked by a 7.3 magnitude earthquake which killed several people and left scars on the Earth that are still visible today.
