May 24, 1989
A huge earthquake ruptured a stretch of seabed about 125 miles north of Macquarie Island, midway between Australia and Antarctica, officials reported. The Australian Seismological Center said the quake had a magnitude of 7.2. The U.S. Geological Survey, which said the temblor was the strongest anywhere in the world this year, put the reading at 8.2. The Australian center said a stretch of seabed from 30 to 60 miles long and up to two miles deep apparently had ruptured, with one geological plate sliding over another.
