UPDATE: No tsunami risk to Hawai’i after 7.4 earthquake east of Japan
No tsunami threat to Hawai’i following a powerful earthquake that struck off the east coast of Japan late Sunday, prompting tsunami monitoring across parts of the Pacific.
Officials were monitoring a potential tsunami threat following a powerful earthquake off Japan, but no action is required for Hawai’i at this time, authorities said late Sunday.
The Pacific Tsunami Warning Center reported at 10:03 p.m. that a magnitude 7.4 earthquake struck at 9:53 p.m. off the east coast of Honshu, Japan.
A tsunami threat did exist for parts of the Pacific Ocean closer to the earthquake’s epicenter. However, officials lifted the threat to the state at 10:46 p.m.
The original alert noted that if a tsunami were to affect the islands, the earliest estimated arrival time would be 5:06 a.m. on Monday, April 20.
