Evidence for migration phenomenon:
An earthquake of Mw 4.0 occurred on 3 June 2017, south of Warna Dam, in the vicinity of the Western Ghat Escarpment (WGE), India. This earthquake is associated with a foreshock–aftershock sequence of 123 events of ML  0.5–3.5, forming an intense cluster. This sequence occurred over a course of one month, beginning in the last week of May 2017, and seismicity continues. This earthquake sequence occurred at a new location compared with the past ∼50 years of seismicity of the region. Prior to the new earthquake sequence of 2017, the earthquakes were bounded between latitude 17.1\(^{\circ}\)–17.4\(^{\circ}\)N, which supports the southward migration of seismicity in the region and suggests that the cluster is a part of the continuing RTS seismicity over the last five decades (Shashidhar et al., 2019a, 2019b).
