Coverage Comparison

Coverage of the quake varied across outlets, with some focusing on the immediate aftermath and others on the broader context of recent seismic activity.

The Hindu reported that the quake was the latest in a series of major temblors hitting the region, noting that the recent spate of quakes during typhoon season has set off worries about mudslides. The report highlighted Japan's proneness to quakes and tsunamis, and noted that a series of quakes has hit lately, including a 7.2 magnitude quake that struck on Thursday in the area close to Sunday's quake. That magnitude was revised upward from a preliminary estimate. The agency has warned other quakes may follow, and a magnitude 5.6 earthquake shook Yamanashi Prefecture and nearby areas, near Mount Fuji and west of Tokyo, on Friday.

In contrast, TASS — English focused on the immediate impact of the earlier Thursday quake, reporting at least five people were hurt in a powerful earthquake in Japan, citing Kyodo. According to the news agency, the casualties were reported from the Iwate and Aomori prefectures, with minor injuries. TASS also reported that a magnitude 7.2 earthquake struck northeastern Japan early on Thursday, with the epicenter located in the Pacific Ocean, east of the Iwate Prefecture. The quake's magnitude was initially assessed at 6.9 but later corrected to 7.2. A tsunami warning was issued after the earth tremor but was cancelled several minutes later. Local residents were warned about potential aftershocks in the coming week.

Another report from The Hindu, dated June 25, provided details on the same Thursday quake, stating that no tsunami warning was issued after an earthquake of magnitude 6.9 struck the east coast of Japan's northeastern Tohoku region, according to the Japan Meteorological Agency. The epicentre was off the coast of Iwate prefecture, at a depth of about 50 km, and no damage from tsunami was feared except for slight sea level changes, the agency said. The quake hit Aomori prefecture with an intensity of 6-plus, a level where typically "it is impossible to remain standing or to move without crawling" on the Japanese scale of 0-7.
