Abstract
We here report our observations of the intense lightning events during ~15:00, 23 September to ~12:00, 24 September 2008 along the fault of Wenchuan-Beichuan counties in Sichuan Province, China where a 8.0 magnitude earthquake strike on May 12th, 2008. This intense lightning period had the highest density in all available the lightning monitoring data of Sichuan. The altered lightning pattern is unlikely to be a coincidence. We also found that the spatial-temporal characteristic of lightning in Sichuan has changed after the earthquake. We studied the correlations and analyze the data between lightning and earthquake in order to understand the seemingly unrelated events.
Highlights
Earthquake is one of major natural disasters, the immediate near-term prediction of earthquake largely remains elusive despite intense investigation, enormous effort and resources worldwide [1-5]

After the 8.0 magnitude earthquake on May 12th, 2008 along the fault of Wenchuan-Beichuan counties in Sichuan Province, which has been showed in Figure 1, another 6.1 magnitude earthquake occurred on August 30th, 2008 in the boundary of Renhe area of Panzhihua and Huili county of Liangshan Yi Autonomous Prefecture that located in the same seismic area, Sichuan Province
Summary
Earthquake is one of major natural disasters, the immediate near-term prediction of earthquake largely remains elusive despite intense investigation, enormous effort and resources worldwide [1-5]. After the 8.0 magnitude earthquake on May 12th, 2008 along the fault of Wenchuan-Beichuan counties in Sichuan Province, which has been showed, another 6.1 magnitude earthquake occurred on August 30th, 2008 in the boundary of Renhe area of Panzhihua and Huili county of Liangshan Yi Autonomous Prefecture that located in the same seismic area, Sichuan Province. These events stimulated us to search for a wide range of natural phenomena that may aid us to better understand the onset of earthquakes. The major seismic area was located in the central segment of “Helan-ChuanDian Tectonic Belt”, which called “China’s North-South Tectonic Belt” and “The Longmen mountain fault zone”
