First, of course, a quick review

Generally speaking, the greatest control on intensity is how far you are from the epicenter the magnitude of the earthquake the local geology how long the shaking lasts

(not a clicker question) forecasting earthquakes is a critical science, but not a well-developed one using foreshocks, seismic gaps, water wells, leveling lines (ground deformation) etc., is worth a try, but right now we know very little about how to successfully predict an eq

What’s smarter than a talking parrot? A spelling bee

Finish the exercise from Monday. be careful: a correlation doesn’t have to be universally true to generally work what characterizes deep earthquakes? what characterizes moderate earthquakes? what characterizes shallow earthquakes? the correlation doesn’t need to be precise, like this, in order to exist! depth damage

While you are communing with your group… Brainstorm for 5 minutes (time keeper?) and agree on THREE things you need to know to feel like you can assess a volcanic hazard
