Total electron content anomalies before 12 January 2010 (Mw=7.0) Haiti earthquake using principal component analysis

Author(s): Jyh-Woei Lin

The aim of this study is to detect Total Electron Content (TEC) anomalies before (Mw=7.0) Haiti earthquake on 12 Jan 2010. Three earthquake-associated TEC anomalies appear at 15:00, 20:00 and 22:00 on 11 Jan 2010 (UTC), 1 day before this earthquake. The analysis results are examined using a mathematical tool called Principal Component Analysis (PCA). After more detailed analysis using PCA, each of three TEC anomalies lasts about 30 minutes.
