Subject: OK, this is weird: Dec. 5: 7.0 quake offshore Santa Cruz, CA |
URL: Burned cars trying to evacuate Lahani fire |
|
At 11:45pm this morning (Dec. 5) I saw online an announcement of a Tsunami warning from a 7.0 quake in California. I quickly logged into my email where I get earthquake & tsunami warning messages. The first message I opened (from the Pacific Tsunami Warning Center, iirc) stated that the 7.0 quake (depth was 8 miles) was 24(+-) miles offshore from Santa Cruz, California and evacuations had been ordered for the town of Davenport (which is directly on the coast), located 10 miles North of Santa Cruz. I read this email message twice to make sure I didn't misread it, then ran into the living room to check the live news reports, which stated that a 7.0 quake occurred offshore of Petrolia in Northern California. HUH?? I quickly rechecked my email and there was NO tsunami warning email for Davenport/Santa Cruz! There were only warnings for Northern California. Premonition, message from Spirit perhaps? I don't know, this is a first for me. Nevertheless, STAY THE WATCH, my friends. One thing I saw on the live news coverage really disturbed me: on San Francisco's Ocean Beach Pacific Coast Highway, vehicles attempting to get away from the coast were moving slow, bumper-to-bumper along only ONE lane of the highway at 12:05pm--and the tsunami was projected to hit at 12:10pm(!!). The police had the highway's Northbound lane cleared of cars while the Southbound lane was bumper-to- bumper, damn! Had the tsunami hit there would have been hundred of deaths. For all you folks living along the coast, you won't be able to evacuate via your rural highways/roads, since the roads will be instantly gridlocked. Plan NOW for alternate evacuation routes to high ground--cut fences (this is what survivors of the Camp/Paradise did)--and tie the cut portions of the fence with thin wire, so you can drive your vehicle through it effortlessly (and another reason: no one will notice your modifications to the fences. It goes without saying, in the event of a mass evacuation order, the 'ell with any No Trespassing sign!). This will help those of you who live along the coastal areas. One last note, then I'll get off my soapbox: when/if you're evacuating by car, remember that the police are under orders to keep open ALL lanes of incoming traffic ("To allow for emergency vehicles"-- which are NOT needed until AFTER the disaster, otherwise emergency personnel are being sent to their deaths) instead of opening ALL lanes to evacuee traffic. They pulled this c**p during the Camp/Paradise fire (where many folks were unfortunately incinerated), the Oroville Dam evacuation, and during the Lahaina fire in Hawaii. Here's a challenge for you: go see your local Chief of Police, and ask them this question, "In the case of a disaster and an evacuation is ordered, WHAT AGENCY controls the roads/highways?" (in other words, what agency gives the Chief his/her marching orders). And then ask them why don't they open all the traffic lanes for evacuees??" Their response ought to be revealing. Do this research NOW, you won't have the luxury of time later. ~Peace!

Thanks, Ryan. I'm wondering if the Pacific Tsunami Center's AI (artificial intelligence) computer program screwed up...this certainly seems plausible.

I have family in that area. There was no large quake offshore Santa Cruz. Santa Cruz and Davenport were mentioned in the origial tsunami warning (which was cancelled) calling for the west coast warning area "down" to Davenport/Santa Cruz on the south end of the warning area.
Yeah, I think some people ..or computers, were pretty mixed up.
There was one main quake..it was offshore Petrolia on the Mendocino fracture and has has many minor aftershocks (as is expected for a 7.0).
Hubby was watching a news show (one of the ABC/CBS/NBC main stream channels) and said they told the audience there were two big quakes.
I had to show him the quake map to reassure him.

initially usgs did show 2 quakes...a six onshore, and a 6.3 offshore...then within 15 minutes or so changed it to a 7 offshore...

yeah..sounds like a computer/seismo glitch. could be a ghost quake. Seismographs very close to the epicenter sometimes get confused. It's a little like trying to determine the direction of the wind from the middle of a whirlwind (or in a 7 or 8 mag quake, the middle of a hurricane).
Sometimes a more distant station will mistakenly determine a strong distant quake as a closer moderate quake and a second quake (ghost quake). These are usually reviewed, revised and eventually removed from the map.
That's why we still need seismologists to double check readings and data coming in and correct. The first readings are almost always "off", but are sent out by computer warning systems in strong quakes to alert emergency agencies who need to know a strong quake has just happened, and where to activate first responders if large enough...they sort out the details later.
Best to give the scientist a full day to revise a preliminary quake. Sometimes, in the case of very large quakes, it can take a week or month to settle on a magnitude when more data is available. As aftershocks fill in the rupture zone, they get a better idea of how much ground actually moved, how deep, long and wide....and the eventual energy released magnitude.
