Tsunami activity in Honiara from twin Solomon quakes

A Tsunami was generated as a result of twin quakes that hit the Solomon Islands region with 49 minutes of each other.

The Pacific Tsunami Warning Center said no tsunami threat existed for other coastal areas in the Pacific.

A gauge located in Honiara measured tsunami waves of 0.06metres or 0.2 feet occurring every 10 minutes.

The waves were measured at 11.04am (Solomon time), just under an hour and a half after the second quake (of 7.2 magnitude) occurred at 8.9 South, 156.6 East at a depth of 33km.

"It may have been destructive along coasts near the earthquake epicenter," the Center said.

It said if no major waves were seen for two hours local authorities could assume that the threat had passed.

But it warned "danger to boats and coastal structures can continue for several hours due to the continuing sea level changes and rapid currents".

It warned that some other areas could experience small non-destructive sea level changes lasting up to several hours.
