Residents in the Kanto region are being urged to remain vigilant for landslides and falling rocks as rain is expected to impact areas recently shaken by a magnitude 5-minus earthquake. The seismic event, which occurred on Tuesday, June 16, at 7:46 p.m., has left the ground in affected areas potentially unstable. According to weather reports, rain is forecast to begin late Wednesday, June 17, and continue into Thursday, June 18, increasing the risk of secondary disasters in locations where the earth was loosened by the tremors.
Seismic Activity in Kanto
The earthquake, centered in the southern part of Ibaraki Prefecture, reached a maximum seismic intensity of 5-minus. This is the second time this year that the Kanto region has experienced an intensity of 5-minus or greater, with the previous event occurring on April 1 in Moka City, Tochigi Prefecture. Data indicates that the tremor was felt across a wide area, ranging from the Tohoku region to the Kinki region, with intensities recorded between 1 and 4. The specific areas reporting a 5-minus intensity include Ota City and Chiyoda Town in Gunma Prefecture, as well as Kazo City, Honjo City, and Misato Town in Saitama Prefecture.
Rainfall Forecast and Hazard Risks
Rain is expected to arrive in the Kanto region starting late tonight, Wednesday, June 17, according to regional meteorological information. The precipitation is forecast to impact the southern part of the region during the morning of Thursday, June 18, and shift toward the northern areas by the afternoon. While the duration of the rainfall is not expected to be long, even light precipitation could trigger landslides or falling rocks in areas where the ground remains weakened from the recent seismic activity. Residents are advised to avoid areas identified as dangerous until the ground stabilizes.
Preparedness Measures for Future Shaking
Authorities emphasize that earthquakes occur without warning, making routine preparation essential. Households are encouraged to maintain a “rolling stock” of water and food, where supplies are consumed and replenished regularly. Additionally, securing furniture to prevent tipping and installing film on glass surfaces to prevent shattering can mitigate risks during future tremors. Families should also establish clear communication plans, designate meeting points, and identify potential hazards—such as unstable ground or dangerous structures—along their daily routes.
