Scientists have located where a meteor crashed to Earth 790,000 years ago, saying the crater from the ancient impact is in southern Laos on the Bolaven Plateau.
Was the crater buried? On Laos' Bolaven Plateau, the scientists found a site where fields of volcanic lava might have hidden signs of an older meteor impact. In a region that the researchers targeted as a likely spot for a crater, most of the lava flows were also in the right age range: between 51,000 and 780,000 years old.
The study authors peered below the lava's surface by taking gravity readings at more than 400 locations. Their resulting gravity map showed one area"of particular interest" with a gravitational anomaly, a subsurface zone less dense than the volcanic rock surrounding it. Their measurements hinted at an elliptical,"elongated crater" about 300 feet thick, about 8 miles wide and 11 miles long, according to the study.
Together, all of these clues suggested that"this thick pile of volcanic rocks does indeed bury the site of the impact," the scientists wrote.
