There is no tsunami threat to Hawaii after a magnitude-7.5 quake near the Solomon Islands, but there may be some small changes in sea level, the city Department of Emergency Management said.

The earthquake struck at 3:27 a.m. Saturday in Hawaii. It was first measured as a magnitude-7.8 quake with a depth of 6.2 miles but it was later downgraded it to 7.5.

Some coastal areas in Hawaii could experience small non-destructive sea level changes and strong or unusual currents lasting up to several hours, the DEM said. The estimated time for these changes is 11:56 a.m. 

Papua New Guinea and the Solomon Islands were under a tsunami warning which was later canceled.

This is the latest in an ongoing sequence of seismicity in the South Pacific region over the past week, which began with magnitude-7.1 and magnitude-6.5 earthquakes near Papua New Guinea on April 11, in the vicinity of the latest quake, according to the U.S. Geological Survey.

Over the past eight days, 45 earthquakes of magnitude-4.5 or greater have occurred nearby.

About 12 hours before this event, a magnitude-6.6 quake struck about 37 miles southwest of Panguna, Papua New Guinea, at a depth of about 15 miles, the USGS said.
