A new study suggests that the Chicxulub asteroid which hit Earth in what is today the Yucatan Peninsula was not the only factor that led to the dinosaurs’ demise.
There was a second killer that scientists haven’t taken into account until now – a massive volcanic eruption in India’s Deccan Traps.
The one-two punch led to the extinction of 75% of the planet’s plants and animals including dinosaurs, researchers believe. Now scientists speculate that the asteroid and the massive volcanic event were somehow connected.
A recent research paper suggests that the Chicxulub meteorite sparked a series of chain reactions in the undersea volcanic ridges thousands of miles away from India’s province Deccan Traps.
The seismic waves tied to the extraterrestrial impact had ripple effects worldwide. One side effect was massive volcanic activity which pushed magma from the mantle to the ocean’s crust.
Chicxulub Asteroid Likely Behind Chain Reaction
Seismicity is often tied to a plethora of events that affect the planet’s water supply. After a major earthquake the level of wells can go up, geyser activity increases, and dry streams can go back to life.
But the most important effect of increased seismicity is volcanic activity. Recent estimates claim that 0.4 percent of eruptions are linked to a major quake.
Study authors believe that the asteroid impact caused seismic activity which led to the relentless volcanic eruptions in India’s Deccan Traps. This province was covered in lava flows for millennia.
Researchers at the University of California, Berkeley, believe the two events and the extinction of dinosaurs are deeply connected. The team found that the space rock triggered an acceleration in the volcanic activity in India which led to the mass extinction.
