If this happened, gases would have trickled out from underground magma chambers over a long period , similar to what is observed today at Mount Etna in Italy and Popocatepetl in Mexico.

[]"This changes our perspective on the role of the Deccan Traps in the K-Pg extinction," lead author Courtney Sprain, a former Berkeley doctoral student who is a postdoctoral researcher at the University of Liverpool in the United Kingdom, said in the same statement.

However, if we are able to initiate a volcanic eruption we could schedule the event and prepare, properly evacuate and effectively eliminate risk to human well being.

Think of it as a geologic Caesarean has reached beyond 12 km in depth.

"This changes our perspective on the role of the Deccan Traps in the K-Pg extinction," said first author Courtney Sprain, a former UC Berkeley doctoral student who is now a postdoc at the University of Liverpool in the United Kingdom.Observations show that after the impact kicked up dust (blocking the sun) or the volcanic gases cooled the climate.The new scenario suggests climate change happened even before the eruptions peaked.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).
