I thought that I heard Burma mentioned somewhere along the line.

I saw a roller go down the coast perpendicular to the shore from my house when I was a kid living in CdM. Right under Cameo Shores headed south to Laguna Beach. There was a set of waves (maybe 10 ?) only on land.  Several feet high, maybe a couple of hundred feet apart.  I don't remember what it sounded like, just seeing the waves sorta kept me from thinking about anything else.  No reports of damage.

It kind of looks like the power pylon handled the acceleration but couldn't handle the deceleration when the shift stops, just as abruptly.

That is such an amazing video. It has been going around the earthquake folks for a couple of days and has created some great discussion. There was (reportedly) a guy in NZ during the M7.9 Kaikoura event who felt strong shaking and ran out of his house. The shaking knocked him down and then the surface rupture (same motion as the video) occurred, directly beneath him. The displacement was about 9 m (27 ft). Since he wasn’t attached to the ground he wasn’t ripped apart; he just went for the ride. Apparently he just ran away.

I’ve always wondered how fast the surface rupture occurs, now I know. 



we visited friends of my sister's in Kaikoura on the last trip and while the rest of the family was ok, one of them was seriously spooked by it.

And the southern San Andreas as well.  Northridge was one vivid example.  1994 6.7 quake, combination slip / thrust fault event which is why the devastation was so much.

The most costly American earthquake since 1906 struck Los Angeles on 17 January 1994. The magnitude 6.7 Northridge earthquake resulted from more than 3 meters of reverse slip on a 15-kilometer-long south-dipping thrust fault that raised the Santa Susana mountains by as much as 70 centimeters. The fault appears to be truncated by the fault that broke in the 1971 San Fernando earthquake at a depth of 8 kilometers. Of these two events, the Northridge earthquake caused many times more damage, primarily because its causative fault is directly under the city. Many types of structures were damaged, but the fracture of welds in steel-frame buildings was the greatest surprise. The Northridge earthquake emphasizes the hazard posed to Los Angeles by concealed thrust faults and the potential for strong ground shaking in moderate earthquakes.


Ya, not the same. Different kind of fault. 1994 not the San Andreas. M6.7 a whole different beast from a M7.7. A southern SAF rupture will be severe.

https://earthquakeinsights.sub...

Here is a summary with a little more detail. These authors are knowledgeable and reputable. They also write this blog for general consumption. Bottom line- this is a bad situation. This strike-slip fault is somewhat analogous to the San Andreas or Alpine (NZ) faults, same sense of motion and similar rates of slip. The fault creates a valley where everyone lives, thus, big population centers are directly over the earthquake. The hypocenter was shallow, less than 10 km, so little energy was attenuated. To add to the problem, the valleys are full of loose (unconsolidated) sediment and prone to liquefaction. The fault has historic, large earthquakes but the infrastructure was not up to standards for that kind of shaking and foundation strength loss. We are better prepared but this earthquake is an analog event to a northern San Andreas scenario.

3 things to know about the deadly Myanmar earthquake
The Sagaing Fault region has a long history of devastating earthquakes

A magnitude 7.7 earthquake that struck March 28 in neighboring Myanmar turned this building in Bangkok, Thailand, into a mountain of collapsed concrete and twisted rubble, and a gargantuan task for rescue workers.
