Michael Poland, a geophysicist with the U.S. Geological Survey's Hawaiian Volcano Observatory, said the earthquake was likely the largest to hit Hawaii since 1989, and possibly the largest since an even larger one measuring 7.2 hit in 1975. Those earthquakes struck less developed areas, Poland said. source
