Prof. Kenyon's recent research has dealt with seismic monitoring of the sudden drainage of supraglacial meltwater lakes into the Greenland ice sheet. This work uses high frequency seismic arrivals recorded by seismometers in the GLISN seismic network, which is coordinated by the Incorporated Research Institutions for Seismology (IRIS). Comparison of seismic arrivals with visual observations of lake drainage, made by the Cryosphere Group at City College, has allowed the identification of seismic waves with unusually low velocities. These waves are apparently being propagated through channels under or within the ice.

Dr. Kenyon has also done work on the use of near surface geophysical techniques, particularly electrical resistivity, in the urban environment. An area of current interest is the use of resistivity to track the tidal forcing of the water table in coastal environments. She has also used resistivity to evaluate the prevalence and anisotropy of subsurface fracturing of igneous bedrock and has used engineering seismology to study the shape of the bedrock underlying Manhattan.

Earlier work, before coming to CUNY, included analytical modeling of magma migration, mantle convection, and the formation of river deltas.
