The ever lucid Phil Plait writes on Bad Astronomy:
Japan suffered a massive earthquake last night, measuring nearly magnitude 9. This is one of the largest quakes in its history, causing widespread and severe damage. Before I say anything else, I’m greatly saddened by the loss of life in Japan, and I’ll be donating to disaster relief organizations to help them get in there and do what they can to give aid to those in need.
While there isn’t much I can do to directly help the situation in Japan, I do hope I can help mitigate the panic and worry that can happen due to people blaming this earthquake on the so-called “supermoon” — a date when the Moon is especially close to the Earth at the same time it’s full. So let me be extremely clear:
Despite what a lot of people are saying, there is no way this earthquake was caused by the Moon.
The idea of the Moon affecting us on Earth isn’t total nonsense, but it cannot be behind this earthquake, and almost certainly won’t have any actual, measurable affect on us on March 19, when the full Moon is at its closest.
So, how can I be so sure?
