So, one of the many challenges you will face/are facing in this earthquake is to find the correct information. Twitter and blogs help immediate access to emergency informationm, but at the same time there are a lot of false rumor and out-of-fate information. The most reliable govermental official sites offer information in Japanese, but not so much in English.
So, I asked the professors in my univeristy where I can find reliable information. Here are some he suggested and I found. Many of them include scienticfic explanations. You may not like reading scientific articles, but they are very easy to understand using a lot of pictures. Read thorough them in order to understand what is actually going on, and to be able to tell truth from false rumors.
