How to get warning of quakes (sort of)

Japan has an Emergency Earthquake Warning System (Kinkyuu Jishin Sokuhou) that uses arrival of P-Waves to warn of incoming earthquakes. It's not 100% reliable but it's far better than nothing.

How to satisfy your morbid curiosity about just how big that quake was

First, there are two ways of measuring quakes which you will hear about in Japan:

Resources listing measurements above for Japanese quakes (both will update fairly quickly after a big quake, though it sometimes takes a few minutes):

What is not helpful and harder to measure: how high you are off the ground and what type of building you are in can have a huge effect on what an earthquake feels like. Some buildings (usually modern earthquake resistant ones like skyscrapers) sway and rock, but others (e.g. older, solider concrete buildings) can shiver like diving boards.

Japan's Aid Organizations

Please add any organizations we should maintain contact with. Please keep it to organizations and contacts within the country. (Ex. the Red Cross is fine, if the contact info or site is the Japan local organization)

Learn from the Past

Post any links to past disaster post analysis, so that we can better understand what may be needed in Tohoku
