7.0 + Earthquake in Northern CA just now

[DeniseM]

Located north of the wine country between Fort Bragg and Eureka - a less populated area than the San Francisco Bay Area - 6.0 is a big one!

Those dots place the activity right on the south edge of the Cascadia Subduction zone.

Multiple sources are revising the intensity to 6.6/6.7. Fortunately, this is a far less populated area than the San Francisco Bay area. It is north of the Wine Country, with farms, rolling hills, and small towns. It will be interesting to see if this wakes up other fault lines in CA.

Tsunami warning called off - thank goodness!

I did not feel the quake at all, but did get the Tsunami warning on my phone...

I got a Tsunami warning on my phone too. I live 300 miles away from the epicenter and more than 40 miles inland from a body of salt water with a mountain range in-between. That is about the distance between the Bay Area and Los Angeles.

Not too worried about Tsunamis...They need to tune their warnings based on geo.

Suppose you had been visiting the coast today? Wouldn't you have wanted the warning? For warning purposes, you are close enough to warrant notice, despite the intervening mountains. Planners need to assume that you are traveling within some reasonable distance of your house.

300 miles from the epicenter is irrelevant. Tsunamis often strike hundreds of miles from the epicenter. Further, if this is a quake on the Cascadia subduction zone, the tsunami hazard is amplified because a subduction zone quakes often involve much more significant sea floor movement than strike-slip quakes, such as as occur on the San Andreas fault system.

From an emergency notification standpoint, and considering it's better to over-notify than under-notify, I think it is personable reasonable for you to have received an alert based on geographic proximity to a coastal region at risk.

Good point. But wouldn't the location of the cell phones to the geographically in danger cell tower be a better indicator of whom to contact? What if I am in LA or in Hawaii and it is hit with Tsunami? Would I not get a notice?

re: 300 miles. This is distance by land not by sea and the tsunami would have to exceed a 2000 foot high mountain range to hit where I live inland in Calif. I worry about a lot of things but Tsunamis near my home are not one of them.

If they can do notice by actual geolocation, that would make sense. I suspect they might not have the enabled. I still get Amber Alerts on my phone when I'm in Hawaii.

I’m just glad it seems there weren’t a lot of injuries or major damage.

It is good to have any distance in the state get a tsunami warning. When the infamous 1964 Alaska Earthquake hit, it was over 9.0 (extreme damage), and tsunamis were observed as far south as Antarctica! So, if you're inland and you get a tsunami warning, you may be safe, but friends/family on the coast may be in danger.
