No 'wave of consequence' yet says Hawaii governor after strong quake in Russia's Far East

"So far we have not seen a wave of consequence," Josh Green told a news conference, adding, however, that they have observed a significant retreat of water.

It will likely be another two to three hours before they can issue an "all clear,” he added.

Following the massive quake – one of the largest on record – the US Tsunami Warning System issued a warning of tsunami waves along some coasts of Russia, Japan, Alaska, and Hawaii.
