Fig. 5From: New aspects of the upper atmospheric disturbances caused by the explosive eruption of the 2022 Hunga Tonga–Hunga Ha’apai volcanoTwo-dimensional maps of band-pass filtered TECs of a–d 30–50 min and e–h 12–20 min periods overplotting the conjugate concentric TIDs after mapping Japan (Australia) TECs to Sothern (Northern) hemisphere. The original and conjugate TECs are indicated by the parula and copper color codes, respectively. The red-dashed circle shows the propagation of the Lamb wave at ∼315 m/s (Lin et al. 2022)Back to article page
