Wow! I am currently experiencing serious underwater-seismometer-envy. This is so cool.
The underwater seismometer network is so great, as evidenced from yesterday's EQ off-Tohoku.

A M6.8 earthquake struck offshore Japan today - another large earthquake from the subduction zone that produced two recent great earthquakes. The earthquake was preceded by a "cascade up": foreshocks progressively increasing in maximum magnitude.

What do we know? What might happen next?

A fascinating read to learn more about the Japan earthquake and the region where it occurred.

Un #sismo M6.8 sacudió la costa de Japón hoy, en la misma zona de subducción que el grande de 2011.
Un “pequeño” #tsunami llegó a tierra con olas <0.2 m; la mayor, 50 min después, recordatorio de que los #tsunamis pueden durar y llegar en varias olas 🌊

Today's Japan M6.8 is in an interesting spot: the zone of "missing" slip just north of the very large shallow rupture in the 2011 M9.

I got elected! (I was unopposed, so it wasn't entirely surprising, but anyway...) Looking forward to serving on the Tompkins County Legislature. Thank you so much to the people who donated, and those who voted. ❤️

Since you probably don’t have four week old foster kittens, I will share this one with you.

The Museum of the Earth isn't just a place to marvel at the physical record of how life evolved on Earth - it also provides virtual access to that collection with remarkable 3D models!

Since Saturday, 51 people donated $4115 to keep the museum open. Help if you can.

Yesterday, thirty-two people donated $1710 to help the Museum of the Earth keep its doors open. 🥰

If you donate (at least $20), let me know and I will send you a 50% off coupon for a year's subscription to Earthquake Insights. Since that's usually $80, you can help the museum AND save money!

Eighteen donors have given almost $1000 to support the Museum of the Earth today!

Let me know if you donate (minimum $20) and I will happily send you a coupon for 50% off of Earthquake Insights. That's normally $80 a year, so you can get a discount AND help out the museum.

As a resident of Ithaca, I am still hopeful that people interested in preserving this paleontological museum will pull through! It is a critical resource for paleontology research and education, and a wonderful museum to visit. If you can donate, please do.
In Ithaca, there's a museum that has the largest collections of fossils from New York AND Antarctica AND Venezuela.

It's grown from a small collection purchased by Ezra Cornell himself nearly two centuries ago.

It will now close in January without help: www.timesunion.com/state/articl...

Terawulf is bullying the Town of Lansing, New York, interfering in our local democracy, and spreading disinformation in order to suit their corporate agenda.
They say they won’t use Cayuga Lake Water, but as Anna Kelles shows, they’ll use millions of gallons per day.
