Japan’s largest earthquake magnitude ever recorded: The world’s first-ever earthquake magnitude is recorded

Japan’s first magnitude-6.9 earthquake struck on April 15, triggering a tsunami warning and a magnitude-7.7 aftershock that killed thousands in the city of Kobe.
More than 5,000 people were injured and at least 11,000 were killed.
The quake, which struck at 3:15 a.m. local time (5:15 p.m., EDT), was recorded in the northeastern prefecture of Shizuoka and centered about 600 miles (1,700 kilometers) northeast of Kobe, where it struck in the middle of a weekend-long weekend that began on Saturday.
The earthquake struck at a depth of 4.3 miles (6.1 kilometers), and a tsunami was expected, the Japan Meteorological Agency said.
Japan’s earthquake agency said the quake was felt as far away as New York City.
A tsunami warning was in effect for the coast and the northern coast of Japan, the U.S. Pacific coastline and the western coast of South Korea.
The tsunami warning for the northern coastal coast was lifted to a depth ranging from 2 to 7.8 miles (4 to 17 kilometers) at 5:15:35 a.t.
(16:15 GMT), the agency said.
It said the tsunami warning would remain in effect until 8:00 a.c.
(19:00 GMT), when the tsunami risk in the region would be reduced.
At least one person died in Kobe after the tsunami triggered a mudslide that damaged a building, according to a local government official.
At the time, a woman wearing a protective helmet said she feared the mudslides would hit the house next door, according the Asahi Shimbun newspaper.
A local police officer in the nearby town of Shimonoseki was injured when he was hit by debris.
The Japan Meteorology Agency did not say when the warning would be lifted or when the magnitude would be officially recorded.
It was the first earthquake to be recorded at such a depth.
Japan is the epicenter of the largest earthquake ever recorded.
The magnitude-9.3 quake was recorded on March 12, 1923, in the same area as this earthquake.
A magnitude-5.6 quake in January 1924 killed more than 400 people in the town of Iwate, Japan.
Japan has suffered numerous major earthquakes, and only two of them occurred in the past two decades.
The biggest of those was a magnitude 6.8 quake in 2012 that killed more the 1,400 people in Kyushu, the most populated province in Japan.
