A geological feature in Michigan’s wooded Upper Peninsula has scientists scratching their heads.
Understanding the Formation and Primordial Evolution of the Earth
The processes that formed the infant Earth set the stage for its subsequent evolution into the dynamic and habitable planet we know today.
P Wave Amplitude Decay Offers a Glimpse of Earth's Structure
Scientists look at deep earthquake signals to map how seismic waves lose energy in the upper mantle across the United States.
Quake or Bomb? Seismic Waves Speak Truth, Even If Nations Don't
When the Earth rumbles and no one knows why, seismologists can analyze the seismic event's waveforms to determine whether a hidden explosion or an earthquake caused the shaking.
Oklahoma's Dormant Faults Hide Huge Seismic Risk Potential
Researchers look at induced seismicity data in Oklahoma to spot an increase of stress in faults that could cause even more damage than recent quakes.
