According to US-based quake researcher Zhonghao Shou, who has been using satellite imagery to predict quakes on the basis of peculiar cloud formations, ancient Chinese and Italians studied special clouds which were indicative of impending earthquakes.
A website on earthquake clouds and short term prediction maintained by him ‘Earthquake clouds and short term prediction’ homepage, states that he had predicted “a China or Neighbour EQ Cloud” more than 24 hours before the Pakistan quake happened.
That is really a good stuff, IMPO.
