Strabo, in his Geography, makes the first accurate description of an earthquake. He writes of a city named Achaea (now thought to be Helice), which fell into the Gulf of Corinth as the result of earthquake-caused subsidence or slumping. Naples, Italy (63 AD)

An earthquake hit the city while Emperor Nero was making his vocal concert debut. Undisturbed, he continued to sing until he was finished. Pompeii, Italy (64)

Thought Mt. Vesuvius was just a volcano? Think again. The Romans witnessed an earthquake that destroyed half the city as well as the Herculaneum. Unluckily for them, they gave no thought to whether the earthquake were the early warnings of a later volcanic eruption, but instead simply rebuilt their cities. Seventeen years later, Mt. Vesuvius erupted, burying Pompeii.

Avalanches can vary in strength depending on factors like the amount of snow involved, the slope angle, and the terrain below. Avalanches have the potential to reach speeds of up to 80 miles per hour and can exert significant force, capable of destroying buildings and trees in their path.
