Earthquake blog: Updates from Utah's 5.7 quake that rocked Salt Lake and the Wasatch Front

SALT LAKE CITY — The strongest earthquake to hit Utah in 28 years rocked the state just after 7 a.m. Wednesday.

The U.S. Geological Survey initially reported the 5.7 magnitude quake hit just northeast of Magna about 7:09 a.m.

No deaths have been reported as a result of the earthquake, Salt Lake County Mayor Jenny Wilson said in a news conference. Various gas leaks and instances of building damage have been reported, she said.

You can watch the news conference at the 10:55 mark below:

A second 3.7 magnitude aftershock hit about 7:15 a.m., according to the USGS, and another 3.5 magnitude aftershock hit shortly thereafter. Dozens of aftershocks happened throughout the day, the largest being a 4.6 magnitude that hit shortly after 1 p.m.

Rumors of a bigger earthquake coming later Wednesday are untrue, according to Utah emergency officials. In 95% of earthquakes, the first quake is the strongest, according to the Utah Division of Emergency Management.

Salt Lake County officials are currently asking people to stay off the roads and stay home if possible.

Gov. Herbert shares message of resilience as many Utahns feel ‘rattled’ by quake, virus

In the wake of a 5.7 earthquake in Magna on Wednesday morning, and ongoing COVID-19 fears, Gov. Gary Herbert reminded Utahns they are resilient and will overcome these trying times. “You didn’t need to feel the earth shake this morning or the numerous aftershocks that have followed in order to feel a little bit rattled,” Herbert said. “Rattled probably describes how many of us have felt as we have tried to understand the threat posed by the coronavirus that is beginning to emerge in our state,” he continued. “These are indeed challenging times. But if there’s one thing I’ve learned over the course of my tenure in office, is that Utahns are resilient and courageous in the face of life’s challenges,” he added. Listen to Herbert’s entire message here.

Authorities release more details on Kennecott hydrochloric acid spill

Officials say there is no risk to the public after about 8,200 gallons of hydrochloric acid leaked from a tank at a Kennecott facility in Magna following Wednesday morning's earthquake.

It was confined to the facility and did not impact public safety, authorities said. All employees were evacuated from the refinery after the spill as a precautionary measure, according to Bennett. There is no timeframe in place for when the refinery will resume operations, he said.

Chemical spill at Kennecott facility contained with no risk to public, authorities say

About 8,200 gallons of hydrochloric acid leaked from a tank at a Kennecott facility in Magna following Wednesday morning's earthquake. Unified Fire Authority Chief Dan Petersen said most of the chemical, which leaked out of a 12,000-gallon tank, was contained to a catch basin in the facility. It was fully contained within the Kennecott building, he said. Officials were concerned that the chemical would mix with another chemical and become more hazardous, but that was not the case Wednesday, Petersen said. A chemical plume dissipated from the facility but was flowing north over the Great Salt Lake and did not impact the public, Petersen said. UFA crews have turned the scene back over to Kennecott personnel, but six hazmat crews were remaining at the scene to monitor the situation, he added. State Route 201 will be closed in the area as crews continue cleaning up the spill.

Utah has been relatively quiet for significant earthquakes over the last 30 years, though the "big one" has loomed over Utahns' collective heads for as long as anyone can remember. Wednesday's 5.7 earthquake was not the "big one," according to the University of Utah. To put things in context it's important to look at the state's history. Check out our interactive map to see the various earthquakes in the last 30 years (none lower than a 2.5 magnitude).

Salt Lake County Mayor: Stay off roads, shelter-in-place if possible

Salt Lake County Mayor Jenny Wilson said people should stay off roads and shelter-in-place if possible due to Wednesday morning's earthquake. No fatalities have been reported as a result of the quake, Wilson said at a press conference Wednesday morning. Some leaking gas lines and damaged buildings have been reported, however, she added. Rumors that a larger, stronger earthquake is coming within the next two hours are not true, according to Salt Lake County Emergency Manager Clint Mecham. It is not possible to predict earthquakes, and in the vast majority of earthquake events, the first quake is the strongest, he said. Unified Fire Authority Chief Dan Petersen said crews are working a hazmat incident at a Kennecott warehouse in Magna. Some chemicals leaked from the warehouse, Petersen said. A chemical plume was being released into the air, but it is going up vertically and not into any populated areas, he said. There were no evacuations at the Kennecott warehouse, Petersen added.
