Do humid days get your attention?
Ah...It does but not to the level of an earthquake. An earthquake can kill you, a humid day is just an annoyance.
A 2.9 earthquake nearby means:
—If you are sleeping you will not wake up.
—If you are standing outside you will probably not notice it.
—If you are inside you may hear a small cup rattling.
Ever seen a hanging chandelier swinging so hard it's hitting the ceiling?
Many decades ago I worked in a tall building in SF.
We had a 6.0 that terrified me—but the 3.0 stuff happened often—think about once a month during that period—and was very minor by comparison.
Loma Prieta was the “World Series Quake,” right?
That one looked like a real mofo, (from afar) even messing up the Bay Bridge, if I remember right?
When we moved to St. Louis in the summer of ‘66, Mom fainted dead away from the heat and humidity. We all thought it was going to kill us!
I was within 1-2 miles straight line from the epicenter of a 3.0 range quake. I was sitting in my living room when it hit. She shock wave and movement was vertical and I felt my entire living room floor lift up then down again.
If you’re near the epicenter of a small but shallow quake, it’s gong to get your attention real fast. Trust me.
What I remember about the Loma Prieta was how long it went on. Most earthquakes I’ve experienced were just a passing jolt. That one had the whole house rolling like it was riding waves on the ocean. Seemed to go on forever, too.
Oh yes, the Bay Bridge, and collapsing the top deck of the Cypress structure onto the bottom deck.
I’d been on that stretch of road several times and every single time I’d look up at the top deck and say to myself “I wonder what this would do in an earthquake?” Every. Single. Time.
Now we know...
About that...
The bottom of the top deck of the Cypress Structure looked like a series of door frames.
An amazingly large percentage of the fatalities were in cars where the concrete cross support fell precisely on the driver's seat of the car. The deeply ingrained 'in case of earthquake get in a door frame' response served them poorly that day.
Pffft!! A 2.9 earthquake. That is nothing.
I have trucks rumbling by on my street that shake the building.
A 2.9 earthquake would not even register.
I have a cousin who slept through the Northridge quake, one mile from the epicenter, in the top bunk!
lucky one
They happened to be on a node, a null point, in the reverberations across the valley. No damage in their immediate area, buildings collapsed one mile to either side.
My best friend embalmed about half the victims. She quit being an embalmer after that.
A 4.5 hit Sonoma County yesterday
Followed a few seconds later by a 3.4 or so.
Not a bad shake. Fairly gentle.
