Here’s the second installment of my now weekly series in which I compile all the neat-o earthquake things I’ve relayed via Twitter over the prior week.
National Tsunami Week
From March 24-30, the U.S. National Oceanic and Atmospheric Administration (NOAA) and Federal Emergency Management Agency (FEMA) teamed up to raise awareness of tsunami hazard, assembling a huge number of resources. Get informed about the tsunami risk to your coast line, and learn what you should do–I compiled their compilations here.
There were some notable earthquake anniversaries this past week: in 1983 a hefty jolt shook Portland–the “Spring Break quake.” In 1964, the largest earthquake in North America’s modern history, the M9.2 Good Friday earthquake, shook Anchorage for several minutes, jostling loose all kinds of landslides and faults, and sent a massive tsunami racing across the Pacific.
Fluid Injection & Induced Earthquakes
A paper was published this week documenting the striking correlation between the timing/location of damaging earthquakes and the timing/location of industrial fluid injection. Oklahoma has this problem, Arkansas has this problem, and the Netherlands has this problem.
Turkey’s Urban Renewal/Quake Retrofitting Plan Kicks In
Earlier this year, the government of Turkey initiated an urban renewal project in Istanbul that will replace deadly apartment blocks with housing built to withstand their inevitable temblor(s).

Some are not as happy as others about this:
Seismic Engineering (failures)
The new eastern (Oakland) span of the San Francisco-Oakland Bay Bridge may have had a bit of a setback this week when dozens of enormous bolts used in its seismic joints failed during seismic testing. Ooops. They’ll be fixed/replaced… but the grand opening may be pushed back. 🙁
YouTube’s “EarthquakeVideoMex” compiled a few new videos of earthquake footage, one from a M6.3 in Mexico a few years ago (with some amazing standing waves in an upper story pool):
…and one from the M6.5 that jolted Taiwan earlier this week.
Earthquakes and Cheese
In potentially the most important earthquake-related development of the week, we learned how the Parmagiano-Reggiano industry recovered from a devastating earthquake that struck almost a year ago and wrecked millions of dollars worth of cheese.

See you next week! Or hopefully before then. Happy reading. Join in the fun and get these in real time @TTremblingEarth on Twitter!
