Very strong earthquake in Montana, USA - July 6, 2017

Update 18:12 UTC: We found this article of the Independent Record which gives a good overview of the impact of the earthquake.

"Montana’s most destructive quakes have occurred farther east. The deadliest and strongest at 7.5 triggered a landslide above Hebgen Lake that killed 28 campers near Yellowstone National Park just before midnight on Aug. 17, 1959. It created a new lake on the upper Madison River called Quake Lake.
In late June 1925, brick school buildings in Manhattan, Logan, Three Forks and Lombard were ruined when the state’s second-worst quake at magnitude 6.9 hit near Townsend. And a series of quakes in the fall and winter of 1935, the largest a 6.3 on Oct. 19, caused four deaths and $4 million in property damage in Helena.
Don’t make too much of the paucity of major seismic events in the Columbia River drainage, said Rebecca Bendick, a geologist and associate professor at the University of Montana.
There’ve been devastating quakes on this side of the mountains since the last ice age, just none when people roamed these parts.

Update 20:33 UTC: Dr. Lucy Jones: "Montana's July 6 quake M5.8 is part of a well-known fault system, Lewis and Clark line. Largest historic quake was Hegben Lake 1959 M7.2"

Update 16:30 UTC: At the time of writing this update we have no signs of any injuries or serious damage

Update 14:51 UTC: The Lincoln, Montana earthquake is the state's largest shaker in a dozen years

Update 14:44 UTC: As we have eaten up our Google maps allowances the Google maps (lower end of the site) are returning an error. Tomorrow they will be back.

Update 10:50 UTC: Lincoln sheriff (closest to the epicenter) : no reported injuries or damage in Lincoln. Power restored.

Update 10:38 UTC: So far no reports of structural damage as far as we could find out. We keep on looking of course. The image below is a common feature after this kind of strong earthquakes.

Update 07:59 UTC: On October 31 1935 Helena was struck by an even stronger earthquake which measured a Magnitude 6.2!
Wikipedia damage report of that earthquake :
There was widespread damage to unreinforced masonry structures in the Helena area with more than 200 chimneys being destroyed. The strongest effects were seen in the northeast, where buildings were constructed on alluvial soil, and in the southern business district, which contained many brick buildings. The most extensively damaged building was the Helena High School, which was completed in August 1935[2] and had just been dedicated in early October. The school buildings, which had cost $500,000, had not been designed to be earthquake resistant. Another building that was totally destroyed and had to be rebuilt was the Lewis and Clark County Hospital. The October 18 earthquake caused an estimated $3 million of damage to property.
The aftershock of October 31 caused an estimated $1 million of further property damage, particularly to structures already weakened by the October 18 shock.
Two people were killed by falling bricks in Helena during the October 18 shock.[2] Two brick masons died as a result of the October 31 aftershock, while removing a brick tower. Images below courtesy Wikipedia

Update 07:53 UTC: Strongest aftershock so far measures M4.4 and happened a few minutes ago.

Update 07:52 UTC: People are getting steady back to sleep as the aftershocks are not being felt in the greater area.

Update 07:49 UTC: The image below shows the aftershocks up to 1 hour after the mainshock.

Update 07:27 UTC: Damage around the epicenter is very likely. Shaking was felt much further, even in California and Washington. Surface rupture likely (Estimate CATnews)

Update 07:26 UTC: Focal Mechanism of the earthquake.
Do beach balls looks like Chinese or Latin to you, check this article "Understanding Beach Balls".
The focal mechanism shows a merely normal faulting. 2 sides of the fault getting out of each other combined with a horizontal movement

Update 07:16 UTC: Theoretical shaking strength based on the number of people and cities who have felt them.

Update 07:14 UTC: An aftershock of M4.0 has just been measured. More aftershocks to be felt by people will probably happen for some time to come. Normally they will gradually decrease in number and strength.

Update 07:10 UTC: CATnews theoretical calculation of the possible damage impact

Update 07:01 UTC: Due to the very high demand (thousands of concurrent users) our Experience reports system is saturated. We apologize for that.

Update 06:59 UTC: Shaking mapped on the locations map

Update 06:49 UTC: Based on the present earthquake parameters (Magnitude, Depth, Population, etc) and our experience with earthquake damage impact, calls this earthquake extremely dangerous and expects some serious damage

Update 06:49 UTC: Shaking map from this earthquake. Due to the very shallow depth, the very strong shaking radius will be rather limited

Update 06:44 UTC: Definitely one of the most powerful earthquakes in the USA since many months

Update 06:43 UTC: Seismogram as recorded in a seismological station near Lincoln
