Surviving an Electromagnetic Pulse (EMP): The Prepare Book

WHAT AN EMP IS - An EMP (electromagnetic pulse) is a burst of energy — from a high-altitude nuclear detonation or a powerful solar storm — that can fry unprotected electronics over a huge area in seconds. - Grid power, internet, cell networks, GPS and many modern vehicles can all fail at once. WHY YOU CAN'T WAIT - There is usually NO warning. You'll know by the symptoms: everything electric dies at once at homes, cars and phones across a wide region. CORE PREP (do these now) 1. Keep a Faraday cage (see the dedicated guide) with: a hand-crank/AM-FM radio, a backup phone with downloaded offline maps and medical PDFs, a flashlight, spare batteries, a digital copy of important documents on a USB stick. 2. Keep a carburetor-era (roughly pre-1990, no engine computer) vehicle OR a bicycle and plenty of fuel stored safely. Modern cars' engine computers are the most vulnerable parts. 3. Store 2-4 weeks of water (1 gal/person/day) and shelf-stable food; a water filter (e.g., Sawyer/Sawyer-type or boiling setup). 4. Cash in small bills; ATMs and card readers need power. 5. Paper maps of your city, state and routes out. 6. A first-aid kit and a 30-day supply of essential meds. 7. A mechanical (non-electric) can opener. 8. A printed phone list of family, doctor, and emergency contacts. IN THE FIRST HOUR - Don't expose protected gear to a possible second pulse; leave the Faraday cage sealed. - Check on neighbors (especially elderly) — calmly. - Conserve phone/data: networks may be jammed or down. - Turn off and unplug sensitive electronics you didn't protect. - Fill bathtubs with water before pressure drops. WHY AGENCIES DO THIS - NASA, the military and critical infrastructure operators harden satellites, aircraft cockpits and control rooms against EMP. You can't build a hardened jet, but you can shield a radio and keep analog backups. The principle is the same: keep one set of essential gear electrically isolated.
