“…Second, beside the proposed/existing methods to discover 460 terrestrial/extra-terrestrial lava tunes, such gravitation data sets (Chappaz et al, 2017), ground penetrating radar (Kaku et al, 2017), morphological analyses and spotting of skylight (Cushing et al, 2007;Whittaker, 2012), we proved InSAR survey is an effective tool to detect lava tube networks. Considering proposed planetary InSAR missions (Carrer et al, 2018;Rosen et al, 2001;Ghail et al, 2016;Kim et al, 2015), it has the potential to be applied to lava tubes on the planetary surface.…”
