In Astrology, a supermoon is a full or new moon that coincides with a close approach by the Moon to the Earth.
The combined effect of the Sun and Moon on Earth's oceans, the tide, is greatest when the Moon is new or full. Full Moons during lunar perigees exert an even stronger tidal force, resulting in more extreme high and low tides. Previous supermoons happened in 1955, 1974, 1992 and 2005. Each year had extreme weather events ,such as, the deadly tsunami in Indonesia occuring two weeks before the 2005 Supermoon.
On March 19, the moon will swing around Earth more closely than it has in the past 18 years, lighting up the night sky from just 356,577 kilometers away. On top of that, it will be full. And one astrologer believes it could inflict massive damage on the planet.
