Anchorage Earthquake

Just saw on the news that a 7.0 earthquake has hit very near Anchorage, and that there is a tsunami warning.

Hope all are ok- for sure there are UAA posters here. Be safe!

(many news outlets have news, and I'm sure it will be shifting all day)
 
Re: Anchorage Earthquake

Many aftershocks, too- looks like they are going down in power. Just happened to be watching CBSN, and their live local coverage showed an aftershock.
 
Re: Anchorage Earthquake

Posted in tLodge but I’m ok, family is ok. Earthquake was 13k away from Anchorage. Still dealing with aftershocks, some roads have cracks, a few sink holes, busted pipes etc. Traffic is a mess, schools have closed. I’m chilling at work, waiting it out and getting paid.

Thankfully we have planned for this and buildings seem ok. Quite scary though.
 
Re: Anchorage Earthquake

I would like to say shoutout to all the engineers developing building codes that allowed the vast majority of our buildings to stand!

Structural guys do not mess around, especially in high seismic areas. I've heard of 500 percent factor of safety in load calculations being not uncommon. Plus in high seismic areas the structures are designed to absorb and distribute the forces within themselves.

I’m glad they don’t mess around!

That kind of post takes a lot of worries from people outside of the area.

Like I told my daughter (9), this is why we do all those drills, why we build our buildings the way we do, to be ready for moments like this.

I assume that the codes are in reaction to the quake in the mid-60's which was considerably worse.

I remember the National Geographic article on the 1964 quake. Yuk.

Anchorage created a park dedicated to the '64 quake. You can see where entire sections of shoreline sheared off 30+ feet into the ocean.
 
Re: Anchorage Earthquake

Good NYT article on Anchorage.

Relevant part:
“We have come a long way since the 1964 earthquake,” said Joey Yang, the chairman of the civil engineering program at the University of Alaska Anchorage. “Anchorage definitely knows about the power and damage a major earthquake can cause to the infrastructure and buildings.”

Developers must undergo rigorous requirements before building here, he added, particularly in some of the most seismically sensitive areas. Professor Yang is part of an earthquake commission that advises city leaders, whom he credited with taking the building review process seriously.

That is no joke, I know construction on buildings has been stopped before because they felt the design wouldn’t handle an earthquake.

I know someone asked it and yeah, 1964 is always on the mind here. I was watching a press conference earlier today and a reporter from LA asked our School District Superintendent how and why the response at schools went so smoothly and the Superintendent responded “well, we do practice this every October.”

I kind of shudder to think what would’ve happened in other cities.

Probably not well here in Indy. Road damage would probably blend in and go unnoticed though...
