Japan Earthquake Alert: New Tremors Felt After Tsunami Warning (Update)

Japan remains on high alert as new tremors continue to rattle regions after recent strong earthquakes and related warnings. The Japan Meteorological Agency (JMA) reports persistent activity, with residents feeling long-period ground motion in some areas.

A magnitude 6.2 quake struck eastern Shimane Prefecture on January 6, registering upper 5 intensity in parts of Shimane and Tottori. No tsunami warning was issued for that inland event, but JMA warned of possible strong aftershocks for about a week due to the shallow focus and historical patterns in the region.

Aftershocks and Long-Period Motion

Multiple aftershocks followed, including a 5.1 tremor, causing swaying in tall buildings far from the epicenter. Long tremors – known as long-period ground motion – affected higher floors, marking a rare Level 4 alert in Tottori.

Experts note the quakes hit near past seismic zones, like the 2000 Tottori event. Officials urge caution, especially in the next few days, as rain could heighten risks like landslides.

Public Reactions and On-Ground Experience

Residents describe intense shaking. In one hotel in an affected city, a manager on the ground floor felt large tremors lasting about 30 seconds, with subsequent jolts prompting screams from guests on upper floors. No injuries reported there, but the experience highlights anxiety amid repeated alerts.

Today (January 15), a shallow 5.6 magnitude quake hit the North Pacific near Kushiro, Hokkaido – felt by some but no tsunami risk or major damage.

Japan’s location on the Pacific Ring of Fire means frequent quakes. Authorities emphasize preparedness: secure furniture, prepare evacuation plans, and stay tuned to official updates. No widespread damage from recent events, but vigilance continues.
