Extreme plate boundary localization promotes shallow earthquake slip at the Japan Trench
The 2011 Mw9.1 Tohoku-oki earthquake is exceptional among great earthquakes for having peak slip of ~50-70 m on the shallowest portion of the plate boundary megathrust. Drill cores and geophysical log...

Our Introduction to Oceanography class took a 5-day field trip to The Ocean, visiting some spectacular spots near Big Sur and Monterey. Some major storm systems battered the coast while we were there, so the weather was.... epic. But so was the geology, biology and oceanography 🙂.

We're not cutting fat. We're cutting off limbs. My heart breaks for the federal workers who were fired and for our country that will be SO much worse off without them. And for what? Federal workers make up less of the US workforce in the last ~century.

Trump wants to substantially cut the federal workforce. Here’s what it looks like.
While federal hiring has increased in recent years, federal workers, as a share of all American workers, remains at a historic low.
