What's with the butterflies and no landslides or mud you ask. That's because the only disaster that befell Kenting (墾丁) and Jhihben (知本, Zhiben, Chipen) was that of news reporting. It is just about possible to visit both these places and not notice Typhoon Morakot came near. There are no crowds, hotels are cheap.
I feel particularly sorry for Jhihben. In some ways it was the one place that was actually improved by the typhoon. The loss of that aging hotel and neighboring ramshackle buildings should have been a blessing. Instead the world had this great video footage of a hotel falling over.
