Abstract:The technology of Computerized Ionospheric Tomography was used to reconstruct the distribution of electron density on UT9:00 from May 8th to May 10th, 2008 before Wenchuan Ms8.0 earthquake that occurred on May 12th.It is found that an ionospheric anomaly had taken place on May 9th, and the aspect about when and where this anomaly occurred is consistent with the conclusion made by VTEC analysis. After eliminating the possible impacts that space weather event existed in the ionosphere, we can undoubtedly maintain that the ionospheric anomaly on May 9th is a precursor of Wenchuan earthquake. Integrating all mentioned above, our study indicates that Computerized Ionospheric Tomography has great opportunities to be widely applied in the field of earthquake prediction.
