Fig. 3From: Spatial analyses on pre-earthquake ionospheric anomalies and magnetic storms observed by China seismo-electromagnetic satellite in August 2018Locations of 123 M ≥ 6.0 earthquakes in the Lombok, Indonesia area, where is about ± 15° in latitudes/longitudes from the 5 August 2018 M7.0 earthquake during 2007–2017. The yellow star and red circles denote the M7.0 earthquake (8.3°N, 116.4°E) and the M ≥ 6.0 earthquakes, respectively. The blue open triangle (7.5°N, 115.0°E), near the M7.0 earthquake, is the location of the TEC value extracted from the GIM for the statistical analysis of finding the PEIA characteristicsBack to article page
