7.2-magnitude earthquake hits Japan's Iwate, four injured
Synopsis
Key Takeaways
A 7.2-magnitude earthquake struck off the eastern coast of Iwate Prefecture in northeastern Japan on Thursday, 25 June, injuring at least four people, according to local media reports. The tremor, initially recorded at a preliminary magnitude of 6.9 before being revised upward, hit at approximately 7:30 am local time at a depth of around 40 km.
Seismic Intensity and Affected Regions
The Japan Meteorological Agency (JMA) recorded an intensity of upper 6 — the second-highest level on Japan's seismic scale of 7 — in Hashikami Town, and lower 6 in Hachinohe City, both in Aomori Prefecture. At an intensity of upper 6, it is reportedly impossible to remain standing or move without crawling, and most unfixed furniture moves or topples, according to the weather agency.
Shaking was felt across a wide swathe of the country, including Hokkaido, Akita, Fukushima, Miyagi, and Yamagata prefectures, as well as Tokyo and its neighbouring prefectures, the JMA said. The epicentre was located at 40.2 degrees north latitude and 142.3 degrees east longitude.
No Tsunami Warning, Nuclear Plants Unaffected
No tsunami advisory was issued following the quake, and authorities urged residents in the most severely affected areas to remain alert for aftershocks of similar magnitude. Operators of the Higashidori and Onagawa nuclear power plants in Aomori and Miyagi prefectures, respectively, as well as the Fukushima Daiichi and Daini plants in Fukushima Prefecture, reported no abnormalities. This is a significant reassurance given Japan's history with nuclear incidents following seismic events, most notably the 2011 Tohoku disaster.
Venezuela Also Hit by Twin Powerful Earthquakes
In a separate development on the same day, two powerful earthquakes struck Venezuela in quick succession, sending strong tremors through the capital Caracas. The US Geological Survey (USGS) recorded a magnitude 7.1 quake at 2204 GMT on Wednesday, followed just one minute later by an even stronger magnitude 7.5 tremor. Both struck near the coastal town of Moron, approximately 160 km west of Caracas.
The Venezuelan quakes were shallow, at a depth of only 10 km, a factor that can significantly intensify surface-level destruction. Venezuela's Acting President Delcy Rodriguez declared a State of Emergency in the wake of the twin strikes, citing widespread damage.
Context and What Comes Next
Japan sits atop the Pacific Ring of Fire and is among the world's most seismically active nations, recording hundreds of earthquakes annually. The northeastern Tohoku region, which includes Iwate Prefecture, remains particularly vulnerable — a reality underscored by the catastrophic 2011 earthquake and tsunami that triggered the Fukushima nuclear crisis. Authorities are continuing to assess damage from Thursday's event. Residents in the affected prefectures have been advised to stay vigilant as aftershock risk remains elevated in the hours following a major tremor.
