Great Alaska Earthquake, 1964-Magnitude 9.2 -Causes & Effects 

This is the most concise and understandable video explaining the immensity of the Good Friday Earthquake I’ve seen yet. Great job.

I was downtown at 5th Ave & C street. The most frightening experience of my life.

My aunt uncle and cousins were there. She said the ground looked like the ocean

I was there ,on 4th ave stopped about fifty ft from the collapse in the street.

Excellent animation. George Plafker also documented a third zone, a zone of relatively small uplift, inboard (northwest) of the zone of subsidence. This zone was confirmed by resurveying precise pre-earthquake surveys along the route of the Alaska Railroad.

My dad was Air Force and we were stationed at Elmendorf AFB in 1964. I was only 8 years old, but I remember it like it was yesterday. I saw a lot of the devastation shown in pictures firsthand. I vividly remember the now iconic 4th Street picture and JC Penney store. My elementary school is in one of them too. It was destroyed. Elmendorf itself was severely damaged. My dad had just walked in the door, still in uniform, when it hit. He knew right away what was going on, kept calm, and grabbed us, kids, to get us to safety. I remember watching TV (cartoons of course :) and suddenly the TV was coming AT me. My dad grabbed me and got all of us out of the house. People were screaming that it was the end of the world. The ground was pitching and rolling so, we could barely stand up. Four and a half minutes is a LONG time. We were blessed to be military because there was no water, no power and it was still cold. March in Alaska is still winter. It would take a while to restore everything. The base had backup and a lot of families were doubling up so those who lived off base and/or had their homes destroyed also had a place to stay. Military members had to report to base asap and get (or give) orders. I didn't see much of my dad for a while. The AFTERSHOCKS were incredible. In the first few months, there were thousands, most over 6.0 on the Richter Scale. The earth shook more often than not. It took about a year for them to diminish. In all of this, as terrifying as it was, the absolute weirdest part of it all was the silence that descended right after it stopped. Earthquakes are LOUD, like a freight train going through your living room. The earth itself was imploding. The silence that came right after had its own sound. It was literally surreal. And then all you could hear was sirens and people yelling and screaming. As this video demonstrates, they learned a lot about earthquakes from this one. It also affected future architecture for safety. I'm so glad about that.

The 1964 earthquake was upgraded to A 9.6 a little over six months after the March 27th quake I was there as I lived there and was working for the city of Anchorage at the time.

This was excellent and showed me things that I knew an noticed in and around South Central Alaska. I was in 4th grade then during the quake in Anchorage. My friends home was ripped apart in Turnagain (you photos showed subduction) , my home was okay an I still live in it. Kayaking around Prince William Sound we saw islands where you walk into the woods off the beach about 50 yards and all of a sudden you would see the forest had raised up like a long wall about 8’, it was bizzar looking. And of course we have also in areas like Turnagain Arm which is in away from the coastal waters, where tree forest were sunk into the Salt water table and of course died and still are as standing dead trees. There was some gruesome measure of life lost by the Tidal Waves of various inlets were towns were located at the back ends were great damage is done.

this video is so useful for my geography project thank u!!

very interesting... thanks!!

I don't think you can prepare for such a thing.

Great video bud

My dad was in the air force and we lived on Elmendorf AFB in 1964 and was in that earthquake. I was only 4.My father took numerous movies of after effects of the earthquake.

give us more please! We want more info, thank you.

Great video, thank you for sharing. ⛰️ 🗺️ 🌋

Great explanation, thank you or that!

The 'secret' is to constantly monitor the height of land mass? Say SF or LA, if the giant underground metal spring shown here in this video, gets tight, the land mass rises. Obviously you can monitor that somehow. Focusing on recent quiet zones especially.

So, our tectonic plates are elastic but not plastic.. what are tectonic plates made of ??

Did this earthquake affect Prince Rupert BC? I'm really curious if it did!

Chile 9.5

Tidal waves = tsunami

También Alaska Terremotos 7.1 Noviembre 30 😰😱😨

not so good friday

"M" Is for motivation

Earthquake resistant buildings. Lmao!

For the transform faults to exist in their present positions would require perfectly synchronized motions between the plates, an extremely dubious event in the natural world. Furthermore the North American and Eurasian plates would be colliding with the formation of a Himalayan type mountains with abundant seismicity which is not seen. The theory lacks a sufficient driving mechanism and this weakness is no more evident as to what could possibly move the giant Eurasian plate especially as subduction pull is not a possibility. There should be subduction zones and transform faults in the Artic Ocean which overall fits poorly into plate tectonic theory. Both Eurasia and North America are connected by extensive continental crust as continental shelves. They are both in reality one continent. If sea levels were lower and the shelves exposed on a map and the connection obvious, the theory might not have caught on and geologists may well now be believing in an entirely different one.

40,686 quakes in 2014!!!!! It is getting worse folks.
