# Japan Seismic Activity Late June–Mid July 2026 > Live situation record from CLSTR: https://clstr.news/situations/japan-june-2026-east-coast-earthquakes > Updated: 2026-07-12T10:33:46.000Z. Sources: 86. Developments: 23. The offshore seismic sequence that began on 23 June intensified on 24 June with a 6.9‑magnitude quake off Iwate, producing Shindo‑6+ shaking in Aomori and several injuries. Aftershocks of magnitude 5.7‑6.1 continued through 28 June, prompting safety checks on railways, power plants and nuclear facilities; no tsunami warnings were issued. Super‑typhoon Mekkhala (downgraded to a tropical storm) and Tropical Storm Higos forced evacuations for more than 2 million residents, cancelled hundreds of flights and train services, and halted production at Toyota’s Kyushu plant. On 30 June a magnitude 2.8 quake struck Miyazaki Prefecture and later a magnitude 4.5 offshore event east of Aomori produced light shaking in Hokkaido, Aomori and Iwate, without triggering a tsunami warning. A magnitude 6.4 quake off Miyakojima on 3 July prompted a brief tsunami forecast predicting only minor sea‑level changes, with no evacuations or injuries reported. From 25 June to 4 July the Japan Meteorological Agency recorded 45 earthquakes of magnitude 1 or higher, including magnitude‑6.3 off Iwate, magnitude‑6.2 in Yamanashi and magnitude‑6.0 in Aomori that caused injuries. The agency reiterated that the concentration of strong quakes during the rainy season raises landslide risk. A further minor event occurred on 14 July when a magnitude 2.4 quake struck the Aizu area of Fukushima Prefecture. The tremor reached Shindo 2, caused no damage and generated no tsunami threat. Authorities recorded the quake as a localized, low‑impact aftershock. Monitoring of aftershocks, infrastructure safety and secondary hazards continues as the sequence unfolds. ## Timeline ### 2026-07-12: Fukushima Prefecture experiences magnitude 2.4 earthquake, no tsunami threat A magnitude 2.4 earthquake hit Aizu in Fukushima on July 14, 2026, reaching Shindo 2 intensity, with no tsunami risk or reported damage. 3 sources. https://clstr.news/cluster/fukushima-prefecture-experiences-magnitude-24-earthquake-no-tsunami-threat ### 2026-07-04: Japan records 45 earthquakes in a week, including multiple magnitude‑6 quakes Japan saw 45 quakes in a week (June 25–July 4, 2026), with several magnitude‑6 events and injury reports, prompting landslide warnings. 4 sources. https://clstr.news/cluster/kenzo-exposes-rolex-resale-loan-scheme-exploiting-borrowers-in-saitama ### 2026-07-02: Miyakojima quake magnitude 6.4 triggers modest tsunami alert A magnitude 6.4 quake off Miyakojima on July 3 2026 prompted a tsunami forecast of less than 0.2 m, with no damage expected. 2 sources. https://clstr.news/cluster/miyakojima-quake-magnitude-64-triggers-modest-tsunami-alert ### 2026-06-30: Japan experiences two minor earthquakes in Miyazaki and Iwate prefectures Japan recorded two mild quakes on July 2, 2026: a magnitude 2.8 in Miyazaki (intensity 1) and a magnitude 4.5 off Aomori (intensity 2), neither generating a tsunami. 2 sources. https://clstr.news/cluster/japan-experiences-two-minor-earthquakes-in-miyazaki-and-iwate-prefectures ### 2026-06-29: Japan records 11 strong quakes since April 2026 Japan has logged 11 magnitude‑5+ quakes since April 2026, including a June 26 shindo‑6 tremor near Mount Fuji and a June 28 shindo‑5 offshore Iwate quake;
