An earthquake coming in at a magnitude 3.7 struck Utah south of Salt Lake City at 0509 hours local time, according to a preliminary report from the United States Geological Survey (USGS). This was enough to be felt by plenty of people in the region, and as a result the tricky tremblor is trending on social media.

There’s absolutely nothing to worry about here. There has been no reports of infrastructural damage, and it’s very unlikely there will be. This quake, which appears to be nearest to the city of Bluffdale, was of a fairly low magnitude but just powerful enough – and at 8.8 kilometres (5.5 miles), shallow enough – to be felt by people. (Remember, magnitude isn’t everything.)

Interestingly, it was also preceded by a smaller earthquake, coming in at a magnitude 3.2, a few minutes beforehand. If the 3.7 event turns out to be the most powerful in the sequence, then this 3.2 event will be retrospectively referred to as a foreshock.

According to the USGS, the shaking intensity peaked in the region at V on the Modified Mercalli Intensity Scale, which uses felt reports by witnesses and peak ground acceleration to denote just how much the ground moved. A V ranking denotes “moderate” shaking and “very light” damage, if any at all. So, again, nothing to fret about.

Unlike, say, California, where felt quakes aren’t really that unusual, Utah isn’t known for its earth-shaking events, but as this tremblor was enough to wake thousands of Utahans up at a rather inconvenient time, it’s making several headlines. One particularly rattled fellow was woken up a bit too early on the day of his wedding.

People are probably wondering what triggered it, and once again, the USGS has got you covered. You can read a detailed report on the tectonic backstory here, but here are the essentials.

This part of the country includes the Intermountain Seismic Belt (ISB), a zone of seismicity that roughly trends north-south. Its quakes can identified as far back as mid-19th Century historical records, although the data here is a little patchy compared to what’s been documented since the advent of modern quake documentation a century or so later.

There are plenty of faults here, including Northern Utah’s Wasatch fault and the splendidly named Hurricane fault in Southern Utah, and as the University of Utah makes clear, the ISB is a pretty active place. As part of their research into this seismic band, they are gathering historical data – news articles, personal accounts, photographs, scientific reports – on it in an attempt to document how often it’s capable of producing potentially damaging quakes above a magnitude 5.0. As you can see here, there have been dozens in the past century or so, and there will be more to come.

These earthquakes, along with the far more numerous smaller magnitude events like today’s, are known as intraplate earthquakes. That means that they are happening far from any tectonic plate boundaries, and instead are occurring within the North American tectonic plate itself.

This isn’t unusual. Due to the constant tug-of-war of this plate with its titanic neighbours, the North American plate is being stretched and pulled and squashed in a very complex manner, which causes faults to slip and earthquakes to occur.

The ISB itself is being driven by an overall horizontal extension; think of it like a piece of pizza dough being slowly pulled apart. The intricate fault network here contains plenty of idiosyncratic responses to that extension, which can result in rare, powerful slips and plenty more low-energy jolts.

There’s still plenty of work to be done when it comes to characterizing these faults and their hazard potential, but those are the basics. It’s not yet clear which specific fault caused this morning’s earthquake, but the ISB is certainly to blame.

As ever, there is a slim possibility that a more energetic quake will occur in the next few days, but it’s more likely that apart from a sequence of less energetic aftershocks, there is nothing more to look forward to or fear in the near future in this respect. This quake, as ever, was just the active earth doing what it does best, and there’s no sign that a major, devastating quake is about to occur.

An earthquake being available in at a magnitude 3.7 struck Utah south of Salt Lake City at 0509 hours regional time, according to a initial report from the United States Geological Study (USGS). This sufficed to be felt by a lot of individuals in the area, and as an outcome the challenging tremblor is trending on social networks.

There’s definitely nothing to stress over here. There has actually been no reports of infrastructural damage, and it’s extremely not likely there will be. This quake, which seems nearby to the city of Bluffdale, was of a relatively low magnitude however simply effective enough– and at 8.8 kilometres (5.5 miles), shallow enough– to be felt by individuals. (Keep in mind, magnitude isn’t whatever)

Remarkably, it was likewise preceded by a smaller sized earthquake, coming in at a magnitude 3.2, a couple of minutes in advance. If the 3.7 occasion ends up being the most effective in the series, then this 3.2 occasion will be retrospectively described as a foreshock.

(*********** )(************ )According to the USGS, the shaking strength peaked in the area at V on the Customized Mercalli Strength Scale, which utilizes felt reports by witnesses and peak ground velocity to represent simply just how much the ground moved. A V ranking signifies “moderate” shaking and “extremely light” damage, if any at all. So, once again, absolutely nothing to stress about.

Unlike, state, California, where felt quakes aren’t actually that uncommon, Utah isn’t understood for its earth-shaking occasions, however as this tremblor sufficed to wake countless Utahans up at a rather troublesome time, it’s making numerous headings.

Individuals are most likely questioning what activated it, and when again, the USGS has actually got you covered. You can check out a comprehensive report on the tectonic backstory here, however here are the fundamentals.

This part of the nation consists of the Intermountain Seismic Belt (ISB), a zone of seismicity that approximately patterns north-south. Its quakes can determined as far back as mid-19 th Century historic records, although the information here is a little irregular compared to what’s been recorded given that the introduction of modern-day quake paperwork a century or two later on.

There are a lot of faults here, consisting of Northern Utah’s Wasatch fault and the splendidly called Cyclone fault in Southern Utah, and as the University of Utah explains, the ISB is a quite active location As part of their research study into this seismic band, they are collecting historic information– news short articles, individual accounts, photos, clinical reports– on it in an effort to record how frequently it can producing possibly harmful quakes above a magnitude 5.0. As you can see here, there have actually been lots in the previous century or two, and there will be more to come.

These earthquakes, in addition to the even more many smaller sized magnitude occasions like today’s, are called intraplate earthquakes. That suggests that they are occurring far from any tectonic plate limits, and rather are happening within the North American tectonic plate itself.

This isn’t uncommon. Due to the consistent tug-of-war of this plate with its titanic neighbours, the North American plate is being extended and pulled and compressed in a really intricate way, which triggers faults to slip and earthquakes to happen.

The ISB itself is being driven by an total horizontal extension; think about it like a piece of pizza dough being gradually pulled apart. The complex fault network here consists of a lot of distinctive actions to that extension, which can lead to uncommon, effective slips and plenty more low-energy shocks.

There’s still a lot of work to be done when it concerns defining these faults and their risk capacity, however those are the essentials. It’s not yet clear which particular fault triggered today’s earthquake, however the ISB is definitely to blame.

As ever, there is a slim possibility that a more energetic quake will happen in the next couple of days, however it’s most likely that apart from a series of less energetic aftershocks, there is absolutely nothing more to anticipate or worry in the future in this regard. This quake, as ever, was simply the active earth doing what it does best, and there’s no indication that a significant, destructive quake will happen.
