Abstract EN
Two-dimensional principal component analysis (2DPCA) and principal component analysis (PCA) are used to examine the ionospheric total electron content (TEC) data during the time period from 00:00 on August 21 to 12: 45 on August 31 (UT), which are 10 days before the M = 7.6 Philippines earthquake at 12:47:34 on August 31, 2012 (UT) with the depth at 34.9 km.
From the results by using 2DPCA, a TEC precursor of Philippines earthquake is found during the time period from 4:25 to 4:40 on August 28, 2012 (UT) with the duration time of at least 15 minutes.
Another earthquake-related TEC anomaly is detectable for the time period from 04:35 to 04:40 on August 27, 2012 (UT) with the duration time of at least 5 minutes during the Puerto earthquake at 04: 37:20 on August 27, 2012 (UT) (Mw = 7.3) with the depth at 20.3 km.
The precursor of the Puerto earthquake is not detectable.
TEC anomaly is not to be found related to the Jan Mayen Island earthquake (Mw = 6.8) at 13:43:24 on August 30, 2012 (UT).
These earthquake-related TEC anomalies are detectable by using 2DPCA rather than PCA.
They are localized nearby the epicenters of the Philippines and Puerto earthquakes.
