Earthquakes

The Earth's crust is not one piece. It is broken into huge slabs called plates, and the plates are always moving — about as fast as your fingernails grow. Where two plates meet, they can catch on each other. Pressure builds up for years while they are stuck. When they finally slip, all that stored energy is released at once. The ground shakes. That shaking is an earthquake. Most earthquakes are too small to feel. A few are strong enough to bring down buildings, which is why new buildings in some places are made to sway.

Inside a Fire Engine

A fire engine carries everything a crew might need, because there is no time to go back for anything. It holds about eighteen hundred litres of water. That sounds like a lot, but a hose can empty it in under three minutes, so the crew connect to a hydrant as soon as they can. Ladders are carried on the roof. The longest can reach a third-floor window. Inside are cutting tools for road accidents, breathing sets for smoke, and a thermal camera that finds a hot spot through a wall. The engine is red so that it is seen. The siren is for when being seen is not enough.
