Tsunami risk after shaking. If you feel violent shaking for 20+ seconds and you are near the coast, do not wait for a warning. Walk to high ground immediately (100 feet elevation or 2 miles inland).
ultimately transcends the individual. When you strap your water heater, you protect the firefighter who would otherwise fight a gas fire at your house instead of rescuing a child across town. When you store 14 days of water, you leave municipal supplies for the hospital and the elderly. quakprep.
But seismologists disagree. The Cascadia Subduction Zone (a 700-mile fault off the Pacific Northwest) has a 37% chance of producing a magnitude 8.0+ event in the next 50 years. In California, the probability of a magnitude 6.7 or higher earthquake in the next 30 years exceeds 99%. Tsunami risk after shaking

When the ground beneath your feet suddenly turns to liquid, milliseconds feel like minutes. The roar of collapsing drywall, the shatter of glass, and the violent sway of overhead fixtures create a unique brand of primal terror. In that moment, there is no time to Google "what to do." There is no time to run to the store for bottled water. There is only the physics of disaster and the quality of your preparation.
Lower frequency, higher intensity potential. Soil here is older and transmits seismic waves farther. Expect liquifaction and building collapse in Memphis, St. Louis, and Evansville. Focus on strapping water heaters and bolting sill plates to foundations.
