The event listed for February 4, 1883, in Kalamazoo, Michigan, in the National Earthquake Catalog is attributable to the accidental railroad explosions in La Porte, Indiana, and is in fact not an earthquake. This is the second largest event attributed to the lower peninsula. No damage occurred in Kalamazoo despite reports by the Chicago press. The distribution of felt reports corresponds to that expected for an explosion in February. The event was further confused with a 5 A.M. earthquake in the Bloomington, Illinois-St. Louis area.
