Science yearns to discover a means to control or stop volcanic eruptions before they begin.
To date there have been no successful efforts to start, stop or reduce a volcanic eruption; however, the ideas exists and discussion is underway.
Previous studies suggested that about 80 percent of the lava erupted before the impact.
If most of the Deccan Traps lava had erupted before the impact, then gases emitted during the eruptions could have been the cause of global warming within the last 400,000 years of the Cretaceous Period, during which temperatures increased, on average, about 8 degrees Celsius (14.4 degrees Fahrenheit).
I would say, with pretty high confidence, that the eruptions occurred within 50,000 years, and maybe 30,000 years, of the impact, which means they were synchronous within the margin of error," said Paul Renne, a professor-in-residence of earth and planetary science at UC Berkeley, director of the Berkeley Geochronology Center and senior author of the study, which will appear online Feb. "That is an important validation of the hypothesis that the impact renewed lava flows." The new dates also confirm earlier estimates that the lava flows continued for about a million years, but contain a surprise: three-quarters of the lava erupted after the impact.Although it was never attempted it was certainly discussed, and could therefore be considered a possible engineering solution to an impending eruption in the future.If we could plan an eruption at Mt Rainier we could direct the blast to the east and away from high population density areas.If most of the lava shot out after the impact, this has large implications for how the extinction played out.
Here's what the standard narrative has been: If most of the Deccan Traps lava burst out before the impact, then the gases it generated could have caused global warming during the last 400,000 years of the Cretaceous.In this scenario the preparation and evacuation of several small communities would be easier and much less disruptive than a volcanic crisis situation facing the Seattle metropolitan area.
