Author(s): Lin Jyh-Woei

Global ionospheric total electron content (TEC) map (GIM) data at the time 07:15:00UT- 07:30:00UT on 17 April, 2012 (UT) is examined by Two-dimensional Principal Component Analysis (2DPCA) in order to detect TEC anomaly related to a deep earthquake at 07: 13:50 UT on 17 April, 2012 (UT) (MW=6.8) with the depth of 208.2km in Papua New Guinea. The TEC anomaly is highly localized around the epicenter and its duration time is at least 10 minutes.
