https://kmud.org the local community radio station in the area is doing regular alerts and they have a local geologist on live now.
Edit: tsunami warning cancelled for entire zone, but you should remain out of evacuation zones out of an abundance of safety. Aftershocks of up to M5 are still happening.
There is a #tsunami warning for much of the NorthCoast, but as of yet, no clear indication that a tsunami was actually produced or will arrive. You should still evacuate if you're in a tsunami warning zone and stay away until given the all clear.
An expert from NWS was just on https://kmud.org saying we likely won't know for another 30 minutes (i.e. ~12:15 PST) whether a tsunami is coming and, if so, how big.
Saying this because I'm seeing lots of people claiming a tsunami is "coming".
