10: 5.12 Wenchuan Earthquake

The infinite sorrow of May is approaching!

These questions are mostly unclear or inaccurate. If you have any questions, please reply to me. Thank you!
1) earthquake prediction: Is it unpredictable or not? First, it is said that a paper published in a publication has made predictions. Who knows where the paper is, what is the publication name, and how it is used, models, and principles? Secondly, the aftershock prediction after the earthquake is still very accurate. Does anyone have more comprehensive and accurate statistics?
2) Post-earthquake report: "soon, more 'hams 'from other places have been found on the earthquake monitoring website in the United States, where a magnitude 7.9 earthquake occurred in Wenchuan, Sichuan, later, this magnitude changed several times." (Http://blog.sina.com.cn/s/blog_4a0bf0dc01009lus.html), who knows when the China Earthquake Administration made a report? Why do we have to go to the United States to check the earthquake in China?
3) News response: "in the more than 20 minutes after the earthquake, most radio stations in Chengdu were playing music, and some were inserting advertisements ...... "(http://blog.sina.com.cn/s/blog_4a0bf0dc01009lus.html) does the press really have such numbness and slowness, or has been panicked?
4) Disaster Relief: I heard that a Jiangsu entrepreneur led the relief team to Chengdu 24 hours a day after the earthquake, 48 hours to Beijing. Is it true? What is the name of this entrepreneur? Who is faster than him? (Of course, Premier Wen is faster than him. I am asking the Relief Team)
