Tsunami waves from Tonga volcano hit California

Edited to add: it looks like a few folks should've moved their vehicles.

1. Thanks for posting this.

Amazing to watch.

2. Tsunami ripples hit California coast. Yes.

3. Every time we have a hurricane, there are people who

leave their cars in flood-prone areas, presumably so the insurance company will get them new ones.

[bahboo]

4. we had a little excitement here in Ventura....

it was amazing to watch....not as dramatic as some of this though...

5. i really wish I knew where this was.

other than CA. that's a lot of coastline.

i think i'll call my brother in Morro Bay see how they're doing.

9. I think that was Santa Cruz. nt

10. Thank you.

Just talked to my brother and my DIL. Morro Bay and El Segundo respectively. I guess the water was up in El Segundo but my brother didn't notice anything in Morro Bay.

Nature will always have the last word.

6. Oh, the humanity! The humanity!

Oh....never mind, oh the walking away at a leisurely pace.

8. The mad, breakneck stroll.

7. Santa Cruz small craft harbor

A few pics from elsewhere but mainly SC.

Note that where you see water spilling onto the parking area/roadway is usually 8’ above high water.

A tsunami isn’t so much a wave as a rapid raising of the tide. That’s what you see here, an area well inside the more or less south facing harbor.

11. The explosion from the volcano itself sent a shockwave around the world

so anyone with a PWS may have captured that as ripple in the barometric pressure.

The #HungaTonga volcanic eruption in the southern Pacific Ocean caused a shockwave that passed through Colorado this morning! This 1 minute data from @NREL Flatirons Campus shows the wave moving through just after 6:00 AM. #cowx
A pressure trace from the NREL Flatirons campus labratory from 5 to 730am. A distinct pressure drop was noted after 6am as a shockwave moved across the area.

Did you know the shockwave from the Tonga volcanic eruption affected pressure here in Minnesota?! Albeit subtle and very brief, that's pretty amazing.

It erupted around 10PM CT on 1/14 and reached MSP at 8AM on 1/15. Pressure blips are visible across the country.

Our local NWS office here in the Philly metro area posted about similar -

Hi Scott/all - while quite subtle, it does appear observing sites in our area picked up the shockwave from the Tonga volcanic eruption also, around 10AM. This graph is from one of our meteorologist's personal weather station in Mt. Laurel NJ. #NJwx #PAwx #DEwx #MDwx

@NWS_MountHolly was this registered here as well?

Everyone sharing pressure traces around world, so figured I'd check my PWS in Miami to see if there was an acoustic wave signature from the #TongaVolcano eruption.

Sure enough there is a 2-3 hPa spike at 930 AM EDT, matching when wave should have been propagating over.

Amazing!

I picked it up on mine (intensity of the change/ripple apparently dependent on location, ambient pressure, altitude, etc. as the wave traveled)-

12. With all this water flowing into unexpected/unusual places

Why isn't its mass causing more tectonic movement on faults such as San Andreas and Hayward in California?

The amount of energy traveling across the pacific and landing against the California coast should surely have more of an effect than some local flooding.

Are we going to be subject to some massive earthquakes in the near future?
