A string of earthquakes shook Japan on Monday, prompting officials to declare tsunami warnings and order evacuations along the country’s western coast.

Iran PressAsia: There were reports of collapsed buildings and people being trapped underneath them. The quake disrupted electricity and phone service, and initially raised fears of a tsunami.

According to the Japanese authorities, 30 people were killed due to the 7.6 Richter earthquake on Monday in this country, but the tsunami warning level on the coast of Japan has been reduced.

Some 45,700 households are without power in Japan's central Ishikawa prefecture after a 7.5 magnitude earthquake struck on Monday, according to the Hokuriku Electric Power company on Tuesday.
