A Recent Seismic Map of the World
From 1980 to the present, a timeline map of every earthquake in the world with a magnitude of 5 or above. You can play around with different parameters and data, so you can see where the different tectonic plates are, just see where the biggest earthquakes occurred, or add in volcanic eruptions. You can also draw a cross section and it will show how deep the quakes occurred along that line.

When I was an earth science teacher and we'd reached the start of the plate tectonics and earthquakes units, I'd print out simple world maps for my students and we'd keep track of similarly-sized quakes for a month or so. Eventually the quakes would form the outlines of the plates, just like this. (I loved that lesson. Long game, good payoff.)
As for My Overall Best Earth Science Lesson, however, the 2001 Nisqually Earthquake happening during 4th period takes the cake. Nothing like a practical lab on L-waves! 😅

Speaking of plate tectonics, it continues to astound me that electronic computers are older (by some 15-20 years!) than the widespread acceptance by geologists of plate tectonics (which happened in the 1960s).

This is the name that'll be displayed next to comments you make on kottke.org; your email will not be displayed publicly. I'd encourage you to use your real name (or at least your first name and last initial) but you can also pick something that you go by when you participate in communities online. Choose something durable and reasonably unique (not "Me" or "anon"). Please don't change this often. No impersonation..
Note: I'm letting folks change their display names because the membership service that kottke.org uses collects full names and I thought some people might not want their names displayed publicly here. If it gets abused, I might disable this feature.
If you feel like this comment goes against the grain of the community guidelines or is otherwise inappropriate, please let me know and I will take a look at it.
