Largest Hawaiian earthquake in a decade reminds us to be prepared

ShakeMap for the June 8, 2017, earthquake shows that strong intensities (yellow color) occurred near the epicenter, and weak intensities could be felt as far away as O‘ahu. Maps like this are produced by a combination of data from strong motion accelerometers and felt reports submitted by the general public through the USGS Did You Feel It? website (http://earthquake.usgs.gov/dyfi).
