BBC also did an article that covered basic comparison between similar incidences in L' Aquila, Port au Prince & Sichuan. Find it below: http://news.bbc.co.uk/2/hi/americas/8510900.stm Interestingly there's a similarly headlined blog post: "Haiti and China: A Tale of Two Earthquakes". http://american-tigress.blog.sohu.com/143547212.html Tony.
