(WEST LAFAYETTE, IN) - A Professor of Geophysics at Purdue University says there are similarities between the fault line that produced Tuesday's earthquake in Haiti and the one that threatens to shake Indiana.
But Professor Eric Calais in the Department of Earth and Atmospheric Sciences says there is one significant difference.
He and others knew the Haitian quake would be a big one.
They have no idea about the New Madrid seismic zone across the mid-western and southern states.
