Japan earthquake: 6.0 magnitude tremor rattles East Coast of Honshu; no casualties reported

A powerful earthquake of magnitude 6.0 struck near the east coast of Honshu , Japan, late Saturday night, the National Center for Seismology (NCS) said.
In a post on X , the NCS said, "EQ of M: 6.0, On: 04/10/2025 20:51:09 IST, Lat: 37.45 N, Long: 141.52 E, Depth: 50 Km, Location: Near East Coast of Honshu, Japan." The agency confirmed the earthquake occurred at a depth of 50 km.

While no casualties have been reported, this is a developing story.

Japan lies in a volcanic zone on the Pacific Ring of Fire , one of the most seismically active regions in the world. The country regularly experiences low-intensity tremors and occasional volcanic activity. Powerful earthquakes, often followed by tsunamis, strike several times each century. Major recent quakes include the 2024 Noto earthquake, the 2011 Tohoku earthquake and tsunami, the 2004 Chuetsu earthquake, and the Great Hanshin earthquake of 1995.

The nation has the densest seismic network in the world, enabling experts to monitor and analyze a large number of earthquakes with high precision.

Unlike many countries, Japan uses the Shindo scale to measure seismic intensity instead of magnitude. While the Richter scale records the energy released at the epicenter, the Shindo scale measures the degree of shaking at different locations. Comparable systems include the Modified Mercalli scale in the United States, the Liedu scale in China, and the European Macroseismic Scale (EMS), reported ANI .
