Earthquake

An earthquake, also called a quake, tremor, or temblor, is the shaking of the Earth's surface

History

During the Doom of Valyria, earthquakes destroyed palaces, temples, and towns, while lakes boiled or turned to acid. The cataclysm fragmented the Valyrian peninsula surrounding Valyria into numerous smaller islands, while the low-lying areas were flooded, creating the Smoking Sea. East of Valyria, Velos and Ghozai on the Isle of Cedars were destroyed by a tsunami.
