A 5.9-magnitude earthquake struck eastern Japan, injuring over 20 people, mostly due to falls and furniture-related injuries while they were caught off guard by the quake while sleeping.

Why it matters

The earthquake highlights the ongoing seismic activity in Japan and the importance of preparedness and safety measures during such events.

Imagine you're sleeping, and suddenly your bed starts shaking. You jump up and try to get out of bed, but you trip and fall, or you hit your head on the door frame. That's what happened to some people during the earthquake in Japan. They were scared and got out of bed quickly, but they weren't careful, and that's how they got hurt.

Analysis

Earthquake Details

The earthquake occurred at 2 a.m. in Ibaraki Prefecture, at a depth of 70 kilometers, an area of Japan prone to frequent quakes. The U.S. Geological Survey recorded a preliminary magnitude of 5.8.

Injuries and Damage

Twenty-three people were injured in four prefectures in the region — nine in Saitama, another nine in Kanagawa, four in Chiba and one in Ibaraki — according to prefectural officials. Most of them were injured when they fell down or hit themselves against furniture or doors as they were caught off guard by the quake while sleeping and got out of bed in a panic, officials said. Among them was a woman in her 80s who fell off the bed and suffered a serious hip injury in Yokohama, in the Kanagawa prefecture, the Yomiuri newspaper reported.

Emergency Response

The quake caused delays to express trains serving Tokyo and Narita Airport and other local trains serving northeastern regions, but Shinkansen bullet trains were running normally, their operator East Japan Raiway Co said. The government set up a task force to assess the extent of possible damage, Prime Minister Sanae Takaichi said on X. The temblor set off emergency quake alerts on mobile phones and also significantly shook Tokyo. NHK public television showed traffic on roads in nearby cities, including Mito and Saitama, seemingly normal. An underground water pipe ruptured in Tokyo’s eastern ward of Koto, with water pouring out onto the road, NHK footage showed. The pipe has been repaired and the leak stopped later. The earthquake caused blackouts to about 460 homes in Tokyo but power was restored by later Sunday morning, according to TEPCO Power Grid.

Key points

  • A 5.9-magnitude earthquake struck eastern Japan, injuring over 20 people.
  • The earthquake occurred at 2 a.m. in Ibaraki Prefecture, at a depth of 70 kilometers.
  • Most of the injuries were caused by falls and furniture-related injuries while people were caught off guard by the quake while sleeping.
  • The government set up a task force to assess the extent of possible damage.
  • The earthquake caused delays to express trains and other local trains, but Shinkansen bullet trains were running normally.
The Upside

The earthquake highlights the importance of preparedness and safety measures during such events. With proper training and equipment, people can minimize the risks associated with earthquakes and stay safe.

The Downside

The earthquake also shows that even with modern technology and infrastructure, there is still a risk of injury and damage during earthquakes. The severity of the injuries and the extent of the damage could have been worse if not for the quick response of the emergency services.
