Asteroid Impact, Schumann Resonances And The End Of The Dinosaurs
We estimate the expected magnitudes of the Schumann resonance fields immediately after the Chicxulub impact and show that they exceed their present-day values by about 5×104 times. Long-term distortion of […]

Evolution After Chicxulub Asteroid Impact: Rapid Response of Life to End-Cretaceous Mass
The impact event that formed the Chicxulub crater (Yucatán Peninsula, México) caused the extinction of 75% of species on Earth 66 million years ago, including non-avian dinosaurs. One place that […]
