Answering your questions:
What do you do in an earthquake?

• If in bed: Stay there, cover your head with blankets and pillow.
• Anywhere else: DROP to the ground, take COVER under something sturdy, HOLD ON until the shaking stops.
• If in bed: Stay there, cover your head with blankets and pillow.
Let’s address this. Human nature has three basic fear responses: fight, flight and freeze. Each can be a decisive action we take when under threat. But, taking the wrong action at the wrong time can cause problems.

During a severe earthquake running away (flight) is the fastest way to get injured or killed. The shaking can be so strong that a fleeing person is knocked to the ground. According to the CDC, 1 in 5 falls leads to a serious injury.

People can also get injured as they run out of buildings where they are safe. Earthquakes cause building materials to plummet to the ground. Skip to 3:35 in this video for an example. https://youtu.be/ij_iBRtBgsI These people are lucky they weren’t killed.

The freeze fear response also won’t serve you well in a quake. We need to act quickly to take cover. Freezing sometimes come from a sense of denial. Sociologists like Dr. Dennis Mileti tells us that humans are very bad at moving from feeling safe to feeling unsafe.

Drop, cover, hold on protects you from nonstructural things that can fall on you and injure you. Remember, we are working with probabilities here. You are more likely to be safe under a table than in other locations. And if you’re outside in an open field, well done!

Based on past earthquake sequences around the world there is a small, about one in 20, chance of an earthquake larger than M 5.7 in the Salt Lake Valley area during the next week.
Although it is possible that larger earthquake in this area could be in the magnitude range of 7.0 to 7.5, the U.S. Geological Survey estimates that the chance of an earthquake of this size is about one in 300.

The Salt Lake Temple, which is undergoing a seismic upgrade, sustained some minor damage during Wednesday morning’s earthquake. The trumpet on the Angel Moroni statue fell off, and there is minor displacement of some of the temple’s smaller spire stones. No workers were injured. Crews on the job site have been sent home for the day, and a full assessment is underway to determine needs going forward. This event emphasizes why this project is so necessary to preserve this historic building and create a safer environment for all our patrons and visitors.
