sniffnoy | Where's Calvin when you need him

Have you all read about the geology on Venus? How there's no real cracks in the crust, no distinct tectonic plates, just one big ("stagnant") lid? How this doesn't allow heat to escape slowly like it does on Earth? How it's hypothesized that every half a billion years or so, the trapped heat finally breaks out in the form of giant volcanic eruptions all over the entire planet, where possibly the planetary entire surface just kind of melts, erasing all record of what came before?

Yeah. You know what they call this kind of worldwide catastrophe?

A global resurfacing event.

That really needs a better name.

ADDENDUM: OK, I'll kick things off and suggest "omnivolcano apocalypse". Or, if we want to to tone things down just a little, perhaps "omnivolcanic catastrophe"?
