For household prep, top priority is water, which may be the hardest thing. At least one 5 gallon jug per person. We have 10 gallons per person, which is pathetically inadequate. Food for 2 weeks. Camp stove with fuel. Flashlights, radios, batteries. Firewood. Extra prescription meds. Gasoline (I keep a 5 gallon jug and I never let my car get below 1/4 tank).
I haven't read the article yet (awaiting my magazine to arrive) but the scariest part is that if a strong earthquake hits the CSZ off Oregon in the spring/summer when the reservoirs are full, the Hills Creek Dam (an earthen dam) could fail. This could then cause Dexter Dam below it fail. Then most of the cities of Springfield and Eugene (about 200,000 people) would be scraped off the face of the Earth.
Do not underestimate the value of print statements for debugging.
