Iben Browning, 73, who gained attention -- and criticism -- last year when he predicted a major earthquake along the New Madrid fault that did not occur, died of a heart attack Thursday in Albuquerque, N.M. A biophysicist who studied climatic cycles, he also worked in such diverse fields as artificial intelligence and bioengineering and held dozens of patents. His projection of a major earthquake around Dec. 3, 1990, was based on tides and '' gravity. The idea was assailed by geologists as lacking a scientific basis. Even so, many residents along the fault, which runs from Arkansas to Illinois, left the area that week as a precaution.

Mr. Nemiroff won a Tony in 1974 for the musical "Raisin," which he and Charlotte Zaltzberg adapted from "Raisin in the Sun."
