BTW our Geomorph has retired, leaving Rob Thomas as the guy to follow. A different Rob Thomas.
Little known fact, 1. Rob and I came from the same program and have been friends for years, 2. He is a master educator (not a little known fact). 3. Iâm retired but still active, dammit
Using information from inside the rocks on Earthâs surface, my colleagues and I have reconstructed the plate tectonics of the planet over the last 1.8 billion years.
It is the first time Earthâs geological record has been used like this, looking so far back in time. This has enabled us to make an attempt at mapping the planet over the last 40 percent of its history, which you can see in the animation below.
The work, led by Xianzhi Cao from the Ocean University in China, was recently published in the open-access journal Geoscience Frontiers.
would be kind of nice if they began at the start and worked forwards..

A magnitude-3.8 earthquake struck
at 9:08 a.m. about 8 miles northeast of Borrego Springs and 20.9 miles
south of La Quinta, according to the U.S. Geological Survey.
A small rattle was felt in the Coachella Valley, including in Indio on Day 2 of the Coachella Valley Music and Arts festival.

Now, with this ~ M4 aftershock the aftershock forecast has changed over the next week. You now have a 16% chance of an M4 ( but less than 1-2 % chance of an M5) and a 76% chance of an M3-3.9. So, youâll likely feel another shake but they SHOULD all be lower than the M4.8 main shock.
Thereâs a lot of science regarding aftershocks, they decay almost exponentially in most earthquakes, so, for this size earthquake they should be done within a week. Larger earthquakes have longer aftershock periods. M7+ earthquakes can have aftershocks for months. Iâve been in some large earthquakes and have been studying some very large ones right after they occur. The aftershocks for those can be large, M5 -6. Those make me jumpy.
So we could have earthquake aftershocks during a solar eclipse. Awesome. Are there any signs of tsunami activity?
