Google Earthquake Crisis Response

Google has set up a great information page for the earthquake here. Also you can donate to the Japanese Red Cross at this page. The Red Cross in Japan is still assessing the situation but if you feel you need to give money now, that is one place to do it. It should eventually be put to good use.

This page has many useful links such as:

• Warnings and advisories
• Disaster message boards
• Transportation status
• Blackout information

The Japanese version of the above page is here.
