A moderate earthquake has hit the U.S. state of Hawaii, but there are no reports of injuries, damage or tsunami warnings.

The 5.2 magnitude earthquake struck in the early morning darkness Friday (5:48 UTC), startling residents of Hawaii's big island. The quake was centered just off the northeast coast of the island, but was felt as far away as Maui, and Hawaii's main island of Oahu, nearly 300 kilometers away.

Hawaii often experiences volcano-related earthquakes, but scientists do not believe Friday's quake was related to volcanic activity.

The earthquake was the strongest felt around Hawaii's big island since a 6.2 magnitude quake struck in 1973.
