I am riding the Caltrain south, we slowed to a snail's pace and they said it would take 2hr+ to get to Palo Alto (from SF). A bunch of people got off, and then the conductor comes back on the PA system to say the speed limitation had been limited and "we'll be going back to 79 MPH, hold on to your hats"

#102This webcam should let us know in a few minutes if this is real: https://www.pacificblue.biz/noyo-harbor-webcam/ Edit: arrival time has come and gone. No indication of movement in water level.
Well I didn't see a Tsunami but thanks to this thread I do have a few nice live streams of pleasant water views going. Kind of relaxing tbh.

#103FORECASTS OF TSUNAMI ACTIVITY ----------------------------- * Tsunami activity is forecasted to start at the following locations at the specified times. FORECAST START SITE OF TSUNAMI ---- ---------- * California Fort Bragg 1110 PST Dec 5 Crescent City 1120 PST Dec 5 San Francisco 1210 PST Dec 5 * Oregon Port Orford 1120 PST Dec 5 Brookings 1125 PST Dec 5 Charleston 1140 PST Dec 5 via https://www.tsunami.gov/events/P…
I should have hit Fort Bragg by now but I'm not seeing that on https://www.noyocenter.org/live-web-cam The earthquake was real but it is probably really hard to predict if that leads to a tsunami.

#106Based on the location and focal mechanism of the earthquake ( https://earthquake.usgs.gov/earthquakes/eventpage/nc75095651... ), this is a strike-slip earthquake on the plate boundary between the Pacific and Gorda/Juan de Fuca plates. Strike-slip earthquakes occur when two plates slide beside each other during an earthquake, usually along a steeply-dipping if not vertical fault. These kinds of earthquakes almost neve…
There are many steep canyons on the Pacific coast, and here is just one example of mass casualties from a tsunami resulting from a submarine landslide triggered by a strike-slip fault earthquake:

#108Cool to see that Google Docs gives me this warning too https://imgur.com/a/B6qSboV
That's it? "Tsunami Warning", no context? no advice on what to do to avoid panic?
Re: Tsunami Warning for Northern California
#109This was confusing because the warning was called off earlier for a different region while still in effect for this one (https://news.ycombinator.com/item?id=42331931).

#110Interesting observation: I am in a circumstance where I am transitioning from an Android phone (Samsung Galaxy) to a iPhone. I observed that android phone alerted me about an earthquake and that I should be ready to feel tremors. To my surprise as I was pondering how this system works - especially wrt to latency - where it alerts me head of time, I then fell small tremors in 2 or 3 seconds after the alert. The tremor…
LTE ETWS/PWS is mandatory feature, iPhones has the same thing. Maybe you've explicitly disabled it, considering (IIUC) US used it for AMBER alerts and had annoyed lots of people at some point. Generally an earthquake warnings are issued by someone always automatically correlating sensors everywhere, USGS and/or NOAA in case with US, and then cellular carriers broadcasting the alert through LTE feature. This does not…
[Edit:] All too real scenario: Carrier knows about particular IP addresses and ports used by alert service. Carrier makes provision for separate path for it. Carrier also tries to shave said provisioning to the bone, calculates a worst-case, and adds 5% capacity. Which doesn't get updated when that particular app gets a 6% boost in subscriptions. Back in the old days the traffic management folks would be on top if it, but that's all been outsourced...
