Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new Johns Hopkins University-led research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.
After a meteor entered Earth's atmosphere over the Western Pacific in January 2014, the event was linked to ground vibrations recorded at a seismic station in Papua New Guinea's Manus Island. In 2023, materials at the bottom of the ocean near where the meteor fragments were thought to have fallen were identified as of"extraterrestrial technological" origin.
Using data from stations in Australia and Palau designed to detect sound waves from nuclear testing, Fernando's team identified a more likely location for the meteor, more than 100 miles from the area initially investigated. They concluded the materials recovered from the ocean bottom were tiny, ordinary meteorites -- or particles produced from other meteorites hitting Earth's surface mixed with terrestrial contamination.
