I am a seismology Ph.D. candidate working in the Alaska Earthquake Center at the University of Alaska Fairbanks with a focus on environmental seismology. 

Do you know the very ground you are standing on now is shaking even without an earthquake?  These faint Earth tremors are called microseisms and are mostly generated by ocean storms. These vibrations are not detectable to humans. However, highly sensitive instruments called seismometers, which are made to detect vibrations, can pick up these signals.  Understanding how this ocean-atmosphere and solid earth system interact and couple is considered the next grand challenge in seismology. 

For most seismologists who study earthquakes, these signals are noises, but for me, these vibrations are very valuable signals that can give much information about Earth. Are you curious about what information these faint termors carry with them? Check out my Research page.
