May earthquake

The May 2003 Miyagi earthquake is an earthquake struck the east coast of the Japanese island of Honshū at 18.24 pm (09:46 UTC) on May 26. [2] The event registered 7.1 on the Japan Meteorological Agency magnitude scale. [3] The quake injured 174 people and caused $97.3 million in damage. [4] It had a maximum Modified Mercalli intensity of IX (Violent), based on damage to a road about 1 km (0.62 mi) from the epicenter. [5]

July earthquake

The July 2003 Miyagi earthquake is a series of earthquakes that occurred in Miyagi Prefecture, Japan on July 26. [6] [7] The seismic magnitude scale of the mainshock was MJMA 6.4. [8] Six hundred and seventy-seven people were injured by the earthquake. [1]
