Recent repeated occurrences of Gas bubbles streaming water jets along Achankovil shear zone of south India and their seismotectonic significance

Achankovil shear zone is a major tectonic crustal segment of south India. The recently observed gas bubbles streaming water jets in the ponds along the shearzone and the minor tremors released between the years 2005–2013 are pointing out the neotectonic activation of Achankovil shearzone, a manifestation of the forthcoming major seismotectonic activities of Indian plate.
