Found this stumbling around YT.  Born and raised and don't remember being taught much about Tulare Lake and whatnot.  Heard about it, but little else.  Do remember that the indigenous made canoes and stuff from the Tule reeds.  And then the baddest fog to be found anywhere, the dreaded Tule Fog.

I'm checking the web cams every time I wake up in the night 



was also confused by the brown ash.. never seen such dirty ash before. looked like an old coal-fired power plant.
.. actually come to think of it, Eyafjallajokull and Etna were frequently pretty grubby. I guess the brown is pulverised country rock/dirt. black juvenile magma and white steam.  
But for a while there it really looked like it was burning through an old car tire pit.

another eruption in the series has started .. quite picturesque if anyone is interested.



ps to work out how high those lava fountains are you can guesstimate by timing how long the highest lava bombs need to fall back to earth.. at the moment it is about 5s which would put them at about 120m / 400 feet tall.

Pretty spectacular eruptions. I think the thing that gets lost in this is that Iceland sits astride the Mid-Atlantic Rift. This is new crust being formed before our eyes! Before GPS we could sort of sum up the amount of lava being erupted and estimate how far the two sides of the rift must move apart to account for this. Now, with GPS, we know precisely how much the two plates, North America and Eurasia are moving from one another. Now think about that motion over thousands or millions of years and you can see how much larger the Atlantic will be (after we’re gone).

Headline's a bit dramatic but now I need to go look. 
Since it is a National Park they need to put it all back. A little glue ought to fix things up.  In all seriousness though, those are some extremely oversteepened slopes. Sounds like the rockfalls are pretty plentiful there. A M7 on the Teton fault would make for some major adjustments.  Hope you take pictures.

At first I was thinking this was a bunch of hype since he was making a big deal about the bathymetry of the Gulf of Mexico. Then, I really liked the way he used analogies to describe the “reason” for the geomorphology of the slope (I won’t give up the secret). Well done. Thanks for sharing!

M. I have another question... this oblique extension regime in Reykjanes.. made up of bookshelf-type blocks accommodating both the slip and the extension motions..  Assuming there is a dyke forming at the moment, wouldn't this reduce the stress on adjacent sections of the main interplate interface (because magma has filled the gap)...i.e. the tectonic movements don't shunt stress down the line, but actually relieve it because ultimately it is extensional rather than compressional ... (does this make sense?)
