Verneshot - End Of World

  A verneshot (named after French author Jules Verne) is a hypothetical volcanic eruption event caused by the buildup of gas deep underneath a craton. Such an event may be forceful enough to launch an extreme amount of material from the crust and mantle into a sub-orbital trajectory.Verneshots have been proposed as a causal mechanism explaining the statistically unlikely contemporaneous occurrence of continental flood basalts, mass extinctions, and “impact signals” (such as planar deformation features, shocked quartz, and iridium anomalies) traditionally considered definitive evidence of hypervelocity impact events.[1]

The verneshot theory suggests that mantle plumes may cause heating and the buildup of carbon dioxide gas underneath continental lithosphere. If continental rifting occurs above this location, an explosive release of the built up gas may occur, potentially sending out a column of crust and mantle into a globally dispersive, super-stratospheric trajectory. It is unclear whether such a column could stay coherent through this process, or whether the force of this process would result in it shattering into much smaller pieces before impacting. The pipe through which the magma and gas had travelled would collapse during this process, sending a shockwave at hypersonic velocity that would deform the surrounding craton.                                        ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,                                                                                                     The four major mass extinctions that may have been caused by verneshots are:

The Frasnian-Fammian extinction event 364 million years ago, killing off 70% of all marine life, linked to the Siljan crater in Sweden and the Pripyat-Dniepr-Donetsk supervolcano in the Ukraine

The Permian-Triassic extinction event 251 million years ago, killing off 96% of all life on the planet, linked to the Bedout submarine potential impact crater off the coast of Australia and the supervolcano forming the Siberian Traps

The Triassic-Jurassic extinction event 200 million years ago, killing off 20% of species, linked to the Manicougan crater in Canada and the Central Atlantic Magmatic Province supervolcano off the coast of Sierra Leone

The Cretaceous-Tertiary extinction event 65 million years ago, killing off 60% of species, linked to the Chicxulub crater in Mexico and the Deccan Traps supervolcano in India

With these four events, massive volcanic activity over thousands of square miles coincides with an impact event. 

It has also been argued that the Tunguska Event may have been caused by a Verneshot (Tunguska would have been the launch site not the impact).
