Volcano: seismic detectors, tar pit geology, and dangers of volcanic ash w/ Joe Ruppel
What is a volcano? \n\n
No, seriously, what is a volcano? A lot of film critics at the time whiffed on this one and at least one or two of us were in the wrong too. Volcano:
\n\nA vent or fissure on the surface of a planet (usually in a mountainous form) with a magma chamber attached to the mantle of a planet or moon, periodically erupting forth lava and volcanic gases onto the surface.
\n\n \n\n La Brea tar pits \n\nPredator/prey capture ratios. Biological activity causing the bubbling and subsequent discovery of a bunch of different bacterai that live in there. Larger things we find fossilized there:
\n\n- \n
- Sabretooth tigers \n
- Mammoths \n
- Giant feline \n
- looooooooads more \n
The different fault types and which of them tend to manifest volcanoes. Spoiler alert: LA has a transform fault which is the kind that is really really really unlikely to sprout a volcano under normal conditions. Transform faults
\n\n Volcano detection \n\n
Major monitoring methods looking out for pending eruptions:
\n\n- \n
- Seisimic activity \n
- Gas! \n
- Groundswell - actual deformation of the landscape from the pressure \n
Pyroclastic flow\xa0vs lava. The eruption of Mt Vesuvius in 79AD. Casting the cavities that surrounded trapped bodies. Cast of a pompeii body
\n\n Volcanic dangers \n\n
Volcanic ash, which is often basically just teeny tiny glass for you to breathe in. Lava temperatures: between holy shit hot and\xa0omg holy shit hot.\xa0 Lava weather systems. Gasses! Lava fountains.
\n\n Measures \n\nDams! Backwards or otherwise. The Decade List.
