May 22, 1910 – Salt Lake City, UT – M 5½ ±

On Sunday, May 22, 1910, at 7:28 a.m. local time, a magnitude 5½ ± earthquake struck Salt Lake City, Utah. At the time, it was the most severe earthquake recorded in the city’s history. Shaking was also distinctly felt in the Utah communities of Tooele, Nephi, Garfield and Bingham; and to a lesser degree in Ogden, Utah.

Frightened people ran from buildings. Some believed that Halley’s Comet had struck the earth. Others thought the end of the world had come. One switchboard in the Salt Lake City reported receiving 5,000 calls in the first 20 minutes of ground shaking. 

There were reports that buildings swayed and houses rocked throughout the city. Light fixtures swung and windows rattled. Books fell from cases, goods were shaken from store shelves, clocks stopped and horses broke out of their stables.

Damage consisted of toppled chimneys, cracked walls and ceilings, falling plaster, and broken mirrors and dishes. The shaking loosened joints in a main gas line, causing severe leaks. One house was damaged when loosened bricks fell through the ceiling.

Though no injuries occurred and damage was minimal, the severe shaking had a sobering effect on the community.

1902 – Pine Valley, UT – M 6±

Intermountain Seismic Belt Historical Earthquake Project

November 17, 1902 – Pine Valley, UT – 6 ±

In the early afternoon of November 17, 1902 residents of Pine Valley, UT were startled by a magnitude 6 (+/-) earthquake. The shaking caused individuals to flee their homes, some being hit by swaying doors and jambs as they ran. Most of the chimneys in town were reportedly damaged. Clocks stopped. Some individuals reported seeing clouds of dust in nearby canyons as rocks weighing many tons came crashing down. Poultry and domestic animals were frightened. Some individuals reported that upon putting an ear to the ground, they could hear a low roar like a stove burning. Though residents were on edge day and night, no one was reported to have evacuated the area.

To the south, in St. George and Santa Clara, there were reports of considerable damage to many buildings. The shaking was strong enough in some buildings to flip hanging pictures completely over. Terrified children and adults ran from homes and other buildings, some experiencing the sensation of seasickness. Many residents were afraid to reenter their homes. Clouds of dust were seen in many directions from falling rocks as far as 25 miles away. It was reported that in some places, hot and cold springs were increased in their flows and waters became muddy.

The earthquake was reported felt in other cities and towns in the surrounding area including Bloomington, Pinto, Cedar City and Toquerville. Individuals in these areas reported damage such as toppled chimneys, falling ceiling plaster, cracked walls, items toppling from shelves, frightened people rushing from buildings and huge boulders rolling down causing clouds of dust. The communities of Lund, Notom, Parowan, Marysvale and Tropic reported feeling the earthquake but suffering no damage.

Felt reports from Salt Lake City mentioned stopped clocks and jarred nerves but no damage. One establishment reported a substance that appeared to be volcanic ash on its windowsills, causing some to question whether the earthquake had activated extinct volcanoes in the southern part of the state. Some individuals speculated that ash from such a volcano could have been carried northward by strong winds. Closer to the epicenter, a few individuals reported seeing smoke above the Pine Valley Mountains and some reported seeing a flash of fire lasting a few seconds, though others reported detecting no evidence of volcanic activity in the area.

On December 4, it was reported that not a day had passed since the initial shock without one or two earthquakes being felt in Pine Valley. A report from St. George on the same day noted that residents there were rejoicing in the belief that the earthquakes had finally ceased – at that point it had been four days since a shock had been felt.
