Most of what L.A. is proposing will also be adopted in Northern California. Study up on the coming future, when our cities will be resilient enough to ride out earthquakes instead of helplessly suffering, then forgetting them. I wrote this piece to bring it to NoCal's attention.

L.A.’s “Resilience By Design” Report Lays Out Ambitious Earthquake Infrastructure Plan

The just-released seismic resiliency plan for Los Angeles goes beyond just saving lives; it hopes to ensure that the nation's second-largest city will still work after a magnitude 7.8 earthquake.

I've been stewing over this thing for years, so it wasn't hard to point out some lessons from the fuckup that had 7 scientists wrongly nailed for manslaughter.

What Can We Learn from the Italian Earthquake Trial?

"When a court convicted earthquake scientists of manslaughter, seismologists everywhere feared the worst for their own efforts at informing the public. After the convictions were overturned on appeal this week, experts, journalists and the general public can consider the wider lessons learned."

This paper gave me new insight into a place I've visited several times but never thought about more deeply.

Yosemite’s Tuolumne Meadows: a Long-standing Geological Puzzle

"One of many iconic landscapes in Yosemite National Park is a wide-open grassy stretch mixed with high granite outcrops called Tuolumne Meadows. Millions of visitors have stopped there in wonder. Geologists love a good view as much as anyone, but sooner or later they ask themselves the strange but typical question, “How did this landscape happen?”
