A university scientist says evidence of the earthquakes in Haiti and Chile turned up in a Nebraska well.

Jesse Korus is a groundwater expert for the University of Nebraska-Lincoln. He says the seismic waves registered on a decades-old instrument.

Korus checked the strip chart recorder in a water well near Aurora on March 2 and found spikes in the water levels chart corresponding to the February 27th Chile quake and January 12th Haiti quake.

Korus says the strip chart recorder is a 1930s technology that uses pen and ink connected to a floating bobber. He says most of the recorders measuring groundwater in Nebraska have been replaced by digital monitors that, because they don't continuously monitor levels, are less likely to record the seismic activity.
