Earthquake weather Earthquake weather Earthquake weather is a type of weather popularly believed to precede earthquakes. Since ancient times, the notion that weather can somehow foreshadow coming seismic activity has been the topic of much discussion and debate. Geologist Russell Robinson has described "earthquake weather" as one of the most common pseudoscientific methods of predicting earthquakes. Aristotle proposed in the 4th century BC that earthquakes were caused by winds trapped in subterranean caves. Small tremors were thought to have been caused by air pushing on the cavern roofs, and large ones by the air breaking the surface. This theory led to a
Type 079-class landing ship 1972 to January 1977 revealed the performance was somewhat satisfactory, but the speed was slow and the ability to operate in bad weather condition is poor. Work immediately begun on redesign named as Type 079II-class, while the first unit subsequently became named as Type 079I. A total of 31 were built, including the conversion of the sole Type 079I to Type 079II standard. 26 were completed by Guangzhou Shipyard International, and 4 were completed by Xiamen Shipyard. Like its predecessor Type 079I, the Type 079II was also designed by 708th Research Institute. The main difference between 079I and 079II is
