Greenland landslide causes 9-day earthquake-like tremors: Study – Times of India
A strange seismic signal detected last September did not resemble a typical earthquake but rather a slow tremor that reverberated for an additional three days. This anomaly prompted scientists to investigate its source.Initially, some scientists thought it was an “unidentified seismic object” because it did not appear to be an earthquake, according to Dr.Stephen Hicks from UCL, a member of the team involved, as reported by the BBC.Hicks noted that the signal continued every 90 seconds for nine days, sparking curiosity among the scientists and leading them to explore the true cause.The team used seismic data to trace the signal’s origin to Dickson Fjord in East Greenland. They gathered additional clues, including satellite imagery and photographs of the fjord taken by the Danish Navy just b...
