yeah, but looking at it again, the distinction is not that clear. I think it was just me seeing patterns where none exist. At first I thought the water was going back and forth and then side to side but it's doing both movements in both phases.
And the quake was quite deep so it would if anything be p and s waves and not rayleigh or love waves, if I understand them correctly, which is unlikely.
However, there were two phases, which could be due to reflection, i.e. two sets of s-waves offset from each other. dunno.
You have a symmetrically asymmetrical tub with the ledge at the one end. It causes a wave all by itself just as a reef on the ocean floor does. Then it rises, breaks, hits the back end for a backwash wave of a type that would not exist if the bottom of the tub was the same throughout. And what is the alignment of the tub in relation to the shock wave, perpendicular or an oblique angle, etc. And was the shock wave itself uniform or distorted ?
What you do have is total chaos in regards to the waves present. This situation is very similar to what we have up here in the Great Lakes, (especially Erie which is very shallow with an average depth of just 55 feet) with swells coming from multiple directions all at the same time, especially in storms. What you saw in the tub is very similar to the wave action that took the Edmund Fitzgerald as it tried to approach and pass through a narrow strait in a brutal storm. Waves reflecting off the banks interacting with wind driven waves from the storm. IIRC the final analysis was waves coming from 5 different directions all at once. And the bow and stern sitting atop the respective crests of two swells leaving the length of the hull out of the water and the weight unsupported a tad too long causing it to snap in half in the middle. Storm waves on the GL's can get up to 50 feet at times, and are very irregular with the short fetches.
We saw those when visiting somewhere. They looked so depressing, but I guess maybe thatâs better than death? Maybe.
So you leave the door open to keep it well ventilated, then when the Tsunami is coming you discover that there is a nest of poisonous snakes in there...
If I am not mistaken, you could see the transition in wave form there. Geomorph can tell which ones.. I'm guessing the first sloshing was secondary and the final side to side motion was caused by love waves. (yes you read correctly).
like quake p and s waves?

I reckon there is a huge need out there for zorbs with some kind of rapid inflation device for people in at risk areas to have stashed at home that they could climb into in an emergency. There are lots of places on the planet exposed to a tsunami risk and no high ground around. And surely, they can't be that costly to manufacture. If they were made of resilient plastic, they would withstand most scenarios.

I remember watching the other Fukushima tsunami on TV live with my family. We watched people running towards overpasses and other high ground - and then it dawned on us that they weren't fast enough. And they were gonna drown right now while we watched.
Easily one of the more disturbing things in recent memory.

One of the last earthquakes I remember from growing up in Cal happened while I was in the bath warming up from a long day of surfing. A pretty good one and I nearly got seasick from the water moving around in the tub, and I never get / got seasick or motion sickness. Pretty disorganizing. The water in our swimming pool kept moving for at least another half an hour afterwards.
The other memorable one was a big roller. Our house was situated at the top of a hill looking down at the ocean. I actually saw the ground rise and fall just like an ocean wave as the shock wave went due south towards Laguna Beach, the next town south. The were several waves kinda like the form of the Loch Ness Monster.
Here is my desktop. The picture is from an exposed portion of the strata at the beach I grew up at just below our house and the soil composition of the land that these shock waves I mentioned above went rolling through.

Thank you for killing my next 20 minutes of productivity. Off to google.

A strong tremor rocked Puerto Rico early Tuesday seriously damaging homes and buildings. The earthquake triggered an automated shut down of all the electricity, leaving much of the island without power. The first quake was followed 10 minutes later by another slightly weaker event, and then multiple aftershocks. Today’s quakes are part of about 50 seismic events arising just off the coast of southwest Puerto Rico since December 28.
The American Red Cross is working with island authorities and the Federal Emergency Management Agency (FEMA) to understand the extent of the damage and identify immediate needs. There are unconfirmed reports of dozens of homes damaged in the municipality of Yauco and road damage leading into Ponce, the 2nd largest city in Puerto Rico. The repeated quakes coupled with power loss is traumatic for communities still recovering from Hurricanes Maria and Irma.
The Red Cross has identified Spanish-speaking disaster mental health workers, emergency supply distribution managers, logisticians, caseworkers, and operations management staff that are on alert to respond in support of the local Red Cross team. The local government operates shelters in Puerto Rico and had one shelter with 10 people overnight as a result of Monday’s quake.
RECONNECT WITH LOVED ONES The Red Cross has two easy ways to help people reconnect. The Red Cross Emergency App features an “I’m Safe” button that allows users to post a message to their social accounts to let friends and family know that they are out of harm’s way. The Red Cross also offers the Safe and Well website, safeandwell.org, which is a private and more secure option. It allows people to list their own status by customizing a message for their loved ones or selecting pre-scripted messages.
RED CROSS APPS Download the Red Cross Emergency App. You can use the app’s Family Safe feature to help stay in touch with loved ones. The First Aid App provides expert advice including what to do for burns, broken bones, and breathing and cardiac emergencies. The apps can be downloaded for free in app stores or at redcross.org/apps
