No tsunami session this year?

The 2020 Sand Point was M7.6 if using the USGS data, inclusive of tsunami data, maybe closer to M7.8. Now that the hazards are past, the quake will be pretty useful for a deeper understanding subduction zones dynamics and tectonics.

Or wait for the county seat officials.

County emergency managers encouraged everyone to have NOAA radios because the siren systems did not extend outside of Uvalde or Del Rio. The radios were easier to maintain than a siren system along rivers. Also, you didn’t have to deal with landowners’ objections.

Yes/no. Val Verde County has a siren system that they use for weather emergencies. Uvalde County we had to have NOAA WX radios. The camp manager had to have one, and all scout troops were given one (this was in the pre smart phone era).

1998 Del Rio flood disaster that wiped out old San Felipe. I have not been back to the area for some time. But us local area kids were always told to avoid certain areas to the point that it was implied knowledge.

I attended a summer camp when I was a kid not too far from the affected areas. We had to place flood markers at the start of camp as part of the weather and EM merit badges. The camp did that because they suffered heavily in the 2002 and 2007 flood events. These also happened not long after the

This isn’t a joke. Someone from the NZ Navy told me about it during last week’s OBS workshop at VUW.

When the fault breaks underground, it often breaks at the speed less than S-wave (or shear wave) speed. This case is referred to as sub-shear rupture. However, if certain physical conditions are met, fault can break at the speed higher than S-wave speed. Such cases are called super-shear rupture.

What is supershear? Asking a fluid dynamics person?

If you're not an oceanographer, you wouldn't necessarily know Joe Pedlosky's name.

He's one of the most celebrated oceanographers of our time, author of a famous textbook and too many papers to count.

But back in the day, before all of that, he was a young professor who said "No". 5/n

Being able to understand people’s cultures and values makes a world of difference when it comes to collaborations. Often times Americans are too crass in this regard and want their cultures reduced to the broad strokes, which is offensive.

My humanities courses were great. I did East Asian culture as part of a study abroad thing and developed a deeper understanding and empathy for my colleagues from that part of the world that many who never took the time lack the appreciation for.

Yeah, it all happened as a means to make them more “employable.” I saw this first hand at UT Austin’s petro engineering program. The sad thing was they added more business classes to make them more hireable. My friend did a business degree along side it, and suffered mental breakdowns on the reg.

My old 2012 era mac from undergrad used to overheat when I did updates or watch netflix near the end of its life. But, it could do lots of scientific coding with no issues. It did a 100,000 x 100,000 maze with no issues in C++.

The now-confirmed and rumored additional cuts to come at NOAA/NWS are spectacularly short-sighted, and ultimately will deal a major self-inflicted wound to the public safety of Americans and the resiliency of the American economy to weather and climate-related disasters.
