Salt Lake City Int'l Airport appears to be temporarily closed after an earthquake occurred nearby this morning. Looks like there's some flooding inside the terminal building:

The fire suppression system in the ATC Tower was leaking. Apparently the backup facility was deemed unsafe, so they had to close the airport.

9S597 diverted to DEN as well. We're hearing SLC ground stop until 1600z, still evaluating runway conditions & power outages reported on the field.

From the airports twitter account:
"The airport is not currently operational. The FAA tower, terminals and concourses have been evacuated. The road to the airport has been opened, so that passengers can be picked-up."

The epicenter was 4 km NNE of Magna, UT, which would be very near the airport.

We had at least 10 seconds of hard shaking at my house, about 14 miles south of the airport.

There's a fault line right through central Utah. So while they're infrequent, it's not like that's an earthquake-proof area.

Looks like the epicenter was a few miles west of KSLC. Only showing a Fedex flight (im assuming a transponder check and not actually getting ready to depart) and a news helicopter active there on flightradar24

While big ones are rare in Utah, they sit right on top of a massive fault. They are also way overdue for a big earthquake. There was a study done a while ago, that a large earthquake would be devastating to SLC. The buildings in the area are not built to withstand them. Let’s pray this relatively small quake is not a precursor, or tremur, to a larger one.

Part of the reasoning for the new terminal build, was to upgrade to withstand a strong earthquake as SLC is near the Wasatch fault line that emergency managers have been warning for decades is capable and due for a strong earthquake.

From DL internal memo: 50 diversions.

I was in south King County when the 6.7 struck and closed BFI because the fill under 32/14 liquefied and made the runways unusable. With Great Salt Lake being near SLC, are there chances of that happening there? The lake has no outlet, so I wonder if this changed the shape of the lake?

Salt Lake City is probably one of the most at risk interior West cities for earthquakes. Those beautiful mountains didn’t just pop up from nowhere. That’s how Earth works.

Soil liquefaction is a definite concern in Utah, and is an engineering problem in most major construction projects. It's not just that the airport is on the edge of the lake either. Most of northern Utah's population lives on a prehistoric lakebed (Lake Bonneville), and liquefaction is a problem everywhere.

SLC airport is slowly coming back online. Several cargo aircraft and biz jet departures and arrivals just a few minutes ago.

As a geologist, I concur.

SLC area is at risk to earthquakes up to 7.0.Classic basin-and-range terrain.

I was going into an office that is near and right next to the SLC airport property. I wasn’t there when the main quake struck but to describe the sounds and motion of the people I talked to, they all thought an airplane had crashed right outside the office building. The were a few strong aftershocks that followed within the hour. Going into, I noticed some of the runway strobe lights were not functioning. There were no planes coming in or taking off which is the norm that time of morning. Wasn’t until I got into the office building that I realized the airport terminal had been evacuated and that the airport was shut down. There was one single FedEx 767 plane on the taxiway and it was still there by the time I left. I’m assuming it couldn’t move since the ATC ground tower was evacuated as well.

It felt bigger than that to me -- I had to grab something to hold on to.

The passenger terminals should be reopened now, according to airport twitter.

It was jarring at first, and resumed after 1300 GMT commercially. GA and cargo were cleared prior.

My concern is the FAA tower closed so they relocated ATC to split between en route and terminal. Terminal control is using the old ATC tower Delta has used as their ops/coordination center. The remainder moved over to SLC center.
Minimal damage, F16 was unusable from damage.

Horrid timing with COVID-19. Nearly all Skywest flights cancelled. Got oddball situations like FedEx’s A300 diverted to Casper of all places. Numerous employees refused to show up (I would’ve called off) airport wide. I saw the amount of cancelled flights (Facepalm)

FlightAware is now showing almost two hour delays for SLC. I thought the airport was reopened. By the way, I live about 60 miles (100 km) from the epicenter of the earthquake and I definitely felt it. It felt like someone bumped into my chair.

Going to be a while too. Tower has structural and equipment damage.

Just a clarification on the towers at SLC, there are three. The ATC tower currently out of service due to the quake. The old ATC tower on top of Terminal 1 normally used by Airport Ops as the "snow desk" for snow removal and as in this case the emergency back up tower for ATC. They are limited to radio and phones only with no radar which is the reason for the reduced arrival and departure rate. The third tower is the Delta ramp tower on top of Terminal 2 which handles the Ops and ground operations for Delta.

As for the quake, I was at home just a couple of miles from the epicenter. Everyone safe and no damage, just a mess from things falling off shelves and tables etc. Between the main quake and the aftershocks, things were rockin' n rollin' Wednesday.

An update article in the SL Tribune today, with a brief discussion of the liquefaction issue mentioned upthread:
https://www.sltrib.com/news/politics/20 ... spur-plea/

If not for Covid-19, I think that this earthquake would have gotten a lot more national media attention. But even locally it has been a secondary story for the media. It was strange to be working from home the day that it hit--under normal circumstances that quake would have shut down the metro area. The governor did in fact tell people to stay out of downtown, but hardly anybody was going downtown anyway. Since I was at home, and had no damage, I felt obligated to work through it all. I think many were in the same situation. That mentality may be part of why the story hasn't been bigger.

This USGS fact sheet is helpful to understand seismic activity around SLC. The current earthquake activity is closest to the Oquirrh-Great Salt Lake Fault Zone, and not part of the better-known Wasatch Fault.
https://pubs.usgs.gov/fs/2016/3019/fs20163019.pdf

I also like this page that gives a nice informative summary of the Wasatch Fault and earthquake history. It's worth a click:
https://utahdnr.maps.arcgis.com/apps/Ca ... 82039403df

In general, the Wasatch fault has major earthquakes about every 300 years. The last big one was about 200 years ago, along a southern segment of the fault.
