Researchers Validate Existence of Deep Earthquake in Utah

3 Haziran 2026Science Daily
  • Scientists have confirmed the occurrence of a deep earthquake in Utah, first detected in 1979, which took place nearly 90 kilometers underground. This finding challenges previous assumptions about the depth at which earthquakes can occur beneath continental regions.
  • Researchers have identified a rare class of 'continental mantle earthquakes' that happen in the upper mantle, an area where rock is generally expected to flow rather than fracture suddenly.
  • The earthquake in question was detected in 1979, but its depth and nature remained a mystery until recent reanalysis of seismic data. This research highlights the importance of long-term data collection and analysis in uncovering geological phenomena that defy established scientific theories.
  • The discovery of these continental mantle earthquakes could significantly alter our understanding of seismic activity and the behavior of Earth's upper mantle. It raises questions about the geological processes at such depths and suggests that our models of earthquake mechanics may need to be revisited.
