Following predictions, they were 2 small EQs within 100 km of LA area during the current high tide season, on lower barometric pressure, and following this trend it is possible to have a similar one today and one between 3 and 4 degrees On June 7 @ 6 PM.
On PCs click on any image and move the wheel.
11:05 Ok so it was one, but at 2 PM or four hours ahead of predicted time.
There are 2 different types of tides and one combination, corresponding to different sides of the world.
Atlantic tides in Europe are 2-3 times higher but happen only 2 times a day. It is like the two peaks combined into one. This could be due to the sheer size of Pacific Ocean. Some say there could be tidal waves, reflections from shores, some say it could be a separation between Sun and Moon influence that is possible only in Pacific. But that separation it is not 100% since the Moon culmination was only 4 hours away and Moon was not pulling vertically.
If so, obviously the peak is not 4 hours delayed like in Moon tides. However, the attraction of the Sun and the tides are half of that of Moon, because of the distance.
Local time in California is one hour ahead due to daylight savings. So 2 PM should actually be 1 PM, right? Also Sun culmination never coincides with noon. So it was a Sun culmination EQ. Patience please cause we're all learning here.
It could also have been a sudden freak variation in atmospheric pressure not recorded by sensors. The gaps in NOAA databases are also very frustrating but is way better than in any other countries and i'm afraid it's all we got.
I did not want to happen this way. I wanted to study it, statistically, and and then build a mathematical formula of the combined Sun And Moon influences and/or run a supercomputer simulation because there are so many influences in tides, but i hit a wall of bureaucracy at USGS so i decided to publish here everything that crosses my mind until we all can draw a conclusion. So please pardon the hiccups.
I should not do this at all but it looks like they keep it to themselves and got all scientists in the world on their payroll (when i wrote this she got up and started to walk and awoke Angela).
Also note that there were was one in San Francisco at the predicted time, minus almost one hour due to position (longitude) though legally it is the same time zone and one similar to the "rogue" one, @noon.
A bunch of them in Mexico, obeying both rules etc. Two while i was writing here in the same area when one happened before those in California which means more could come on the West Coast as we speak. Right now both Sun and Moon are on the other side of the Earth.
It looks like all west coast eqs during this high tide seasons can be grouped by hours, like around noon, around 5, around 9 in the morning or like about 4 hours before tidal peaks and they are indeed linked to atmospheric pressure.
I will try to draw some histograms tomorrow.
There are more high tides ahead. One peak is on 4th of July, corresponding to the big one in 2019 when atmospheric pressure was higher above 1015 mb. However during the current season the tides were higher, like 6.75 vs 6.35 in 2019 and during this 4th of July they will be 6.62. So we just dodged some.
