An earthquake measuring 6.2 on the Richter scale strikes Japan’s Hokkaido prefecture, without triggering a tsunami alert.


A powerful earthquake jolted the Hokkaido prefecture in northern Japan on Sunday evening, with a preliminary magnitude of 6.2, as reported by the Japan Meteorological Agency. The quake’s epicenter was located off the coast of the town of Urakawa, and fortunately, no tsunami warning was issued.

On June 12, 2023, an earthquake with a magnitude of 6.2 on the Richter scale struck Hokkaido prefecture in Japan. Fortunately, this earthquake did not trigger a tsunami alert. The Richter scale is a measurement used to quantify the magnitude, or strength, of an earthquake. In this case, the earthquake was considered moderately strong, but it did not generate a significant tsunami threat to the coastal areas. However, earthquakes can still cause damage and pose risks to structures and the safety of people in the affected region. It is important for residents and authorities to remain vigilant and take necessary precautions to ensure the safety and well-being of everyone in the affected area.

The seismic activity occurred at a depth of 140 kilometers (87 miles), resonating across the region. The cities of Chitose and Atsumacho were among the areas affected by the tremors. While there were no immediate reports of issues at nearby nuclear plants, power outages, or disruptions to bullet train services in northern Japan, precautions were advised by the agency to be vigilant for potential landslides and subsequent earthquakes in the following days.

Local train and metro services experienced delays, and a section of a road was temporarily closed off in response to the earthquake. Footage from a Hokkaido airport revealed displays swaying slightly during the shaking, which lasted for approximately 20 to 30 seconds, according to a witness interviewed by a news broadcaster.

The impact of the earthquake extended beyond Hokkaido, reaching portions of northern Honshu, the largest island in Japan where Tokyo is situated. However, the capital city was not significantly affected by the seismic event.


This recent earthquake in Hokkaido follows a magnitude 6.1 tremor that struck the eastern coast of the island on February 25, as reported by the United States Geological Survey. The previous earthquake’s epicenter was off the Nemuro peninsula, at a depth of 61 kilometers (38 miles), according to the National Research Institute for Earth Science and Disaster Resilience (NIED). Fortunately, no tsunami warning was issued in relation to that earthquake as well.

As a country located in the Pacific Ring of Fire, Japan is well-aware of its vulnerability to earthquakes. The nation has implemented strict building codes and disaster preparedness measures to mitigate the risks associated with seismic activity. Nonetheless, these natural events serve as reminders of the constant need for vigilance and readiness in earthquake-prone areas.
