A powerful earthquake off Russia’s east coast triggered tsunami waves across the Pacific, prompting alerts in Hawaii and California.

Russian agencies have warned a new powerful earthquake near the Pacific's Kuril Islands could trigger a tsunami wave up to 19 centimeters (7.5 inches).

If the earthquake triggered memories of last year's big shake there are some key differences. Last year's earthquake centered near Tewksbury, New Jersey, was a magnitude 4.8. That's almost 20 times stronger than Saturday night's earthquake.

A magnitude 3.0 earthquake centered in New Jersey briefly shook NYC Saturday night, prompting emergency guidance but no major damage.

A minor, 3.0-magnitude earthquake struck in New Jersey on Saturday, according to the United States Geological Survey. The temblor happened at 10:18 p.m. Eastern about 0 miles northeast of Hasbrouck Heights, N.J., data from the agency shows.
