Based on shallow geophysical data, Klanica et al. (2020, https://doi.org/10.1029/2020JF005663) argued that the deepest undewater cave in the world, the Hranice Abyss (HA) had formed by epigenic karstification related to mid‐Miocene opening of ∼1 km deep Carpathian Foredeep (CF) and, hence, could be ∼1 km deep. However, the CF subsided and the abyss was uplifted due to post mid‐Miocene faulting with at least 460 m vertical offset, which makes the depth estimate of Klanica et al. (2020, https://doi.org/10.1029/2020JF005663) invalid. It remains unclear under which geological circumstances the HA, if formed by epigenic karstification, could be backfilled with water column reaching ∼400 m of height.

世界上最深的水下洞穴Hranice Abyss能否真正达到1公里的深度？Klanica等人对论文的评论。（2020年）

根据浅层地球物理数据，Klanica等人。（2020，https://doi.org/10.1029/2020JF005663）认为，世界上最深的无水洞穴Hranice Abyss（HA）是由表生岩溶作用形成的，该成岩作用与中新世中期约1 km深的喀尔巴阡山脉Foredeep（ CF），因此可能约为1公里深。然而，由于中新世后断层的垂向偏移至少为460 m，CF陷落并深渊隆起，这使得Klanica等人进行了深度估算。（2020，https://doi.org/10.1029/2020JF005663）无效。尚不清楚在哪种地质情况下，如果表生岩溶作用形成的HA可以被回填至约400 m高的水柱。
