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?

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.

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!

NOAA’s National Weather Service holds the federal responsibility for tsunami warnings, and has historically been a primary supporter of seismic data collection in Alaska
NOAA cancels longstanding funding for seismic data collection crucial to tsunami warning systems
The Alaska Earthquake Center has long provided NOAA with seismic data for tsunami monitoring and warning purposes. That work will wind down in November, after the federal agency said it can no longer fund the contract.

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...
