Answer:
1-Don't. During a thunderstorm, avoid open vehicles such as convertibles, motorcycles, and golf carts. Be sure to avoid open structures such as porches, gazebos, baseball dugouts, and sports arenas. And stay away from open spaces such as golf courses, parks, playgrounds, ponds, lakes, swimming pools, and beaches.
2-The nature of seismically-triggered landslides
The most abundant types of earthquake-induced landslides are rock falls and slides of rock fragments that form on steep slopes. ... This can have devastating effects during large earthquakes.
3-Brick and concrete buildings have low ductility and therefore absorb very little energy. This makes them especially vulnerable in even minor earthquakes. Buildings constructed of steel-reinforced concrete, on the other hand, perform much better because the embedded steel increases the ductility of the material.
4-Earthquake safety boils down to three basic steps: 1 - Drop to the ground Take cover by getting under a sturdy desk or table - Hold on to it until the shaking stops. ... If you are outdoors, move to a clear area if you can safely do so; avoid power lines, trees, signs, buildings, vehicles, and other hazards.
5-A very large amount of electric current is generated during a lightning strike. The air in the path of lightning heats up enormously. ... Thus, we see that lightning is accompanied by large amounts of electric current and very high temperatures, both of which are very dangerous.
