Poseidon (/pɵˈsaɪdən/; Greek: Ποσειδῶν, pronounced [pose͜edɔ́͜ɔn]) is one of the twelve Olympian deities of the pantheon in Greek mythology. His main domain is the ocean, and he is called the "God of the Sea". Additionally, he is referred to as "Earth-Shaker" due to his role in causing earthquakes, and has been called the "tamer of horses". He is usually depicted as an older male with curly hair and beard.

Dr. Susan Hough of the US Geological Survey argues that hidden throughout history are a glut of giant earthquakes that either went unrecorded or have been underestimated. The upshot being that the risk of future "big one" quakes is likely higher than we've been assuming.
