A consumer Geiger counter answers one question — is the level going up, down or normal? — and none of the first-24-hour decisions. What to look for, what is marketing, and the models people compare.
One base list — the seven items Ready.gov names — plus a climate layer: sleeping bags and sand up north, a gallon of water per person in the desert, a window breaker in flood country.
Over half of US flood drownings happen in a car driven into water. Six inches knocks you over, twelve carries the car. Before, during and after an urban flood — including the renter version.
You do not heat the house, you heat one room — with something that cannot fill it with carbon monoxide. Heat sources from safest to deadliest, the 20-foot rule, and when to leave.
Not a doorway. An earthquake plan for a family: what to bolt down, why sturdy shoes tied to the bed prevent the most common injury, the drill to practise before October 15, and who to text.
The family kit plus one rule most parents get wrong: ready-to-feed formula, not powder, because mixing needs clean water you may not have. Diaper math, medicines, the comfort object.
A wildfire evacuation is decided before the smoke: half a tank of gas, a go-bag by the door, two routes out and a place that takes your dog. The checklist, in the order things happen.
An eight-stage carbon filter certified for taste is not an emergency purifier. The CDC’s test is absolute pore size: 1 micron for parasites, 0.3 for bacteria, and no filter removes viruses. Six gravity filters compared on that basis, with the catch for each.
Most people fear lava when they think about volcanoes. Lava kills almost no one — it moves at 5 mph and you can walk away from it. The real killers are pyroclastic flows (700°C gas clouds moving at 450 mph), volcanic ash (which collapses roofs and destroys engines), toxic gas emissions, and lahars (volcanic mudflows …
The research on disaster survival is unambiguous: neighbors who know each other recover faster, lose fewer people, and coordinate more effectively than isolated households — regardless of how much gear either side has. During Hurricane Katrina, the neighborhoods with established social networks had dramatically better outcomes than equally poor or equally well-equipped neighborhoods without them. …
