Three minor earthquakes Wednesday morning shook areas along the U.S. Pacific Coast, including Alaska, and a tremor hit Hawaii late Tuesday, officials said.
All four quakes were between magnitude 3.0 and 3.9 on the Richter scale, the U.S. Geological Survey said. That is defined as strong enough to be felt but unlikely to cause any real damage. About 49,000 quakes in that range are reported worldwide every year.
