Ionospheric anomaly
Web1 mei 2014 · Therefore, the pre-earthquake ionospheric anomaly is one of hot researches recently. February 12, 2014, a large M w7. 3 earthquake occurred in Hetian, Xijiang, whose epicenter was located in Yutian (82. 5° E, 36. 1°N) with the hypocentral depth of about 12 km. This is a strike-slip earthquake. We use the global ionosphere maps (GIM) provided ... Web23 okt. 2024 · To analyze the winter anomaly in TEC, we used TEC global ionospheric maps for 1998–2015. GIM involve absolute TEC values for the entire globe with the 2.5° latitude and 5° longitude spatial resolution. The total dynamics of GIM TEC from different laboratories generally agrees, despite systematic differences ( Afraimovich et al., 2008 ).
