Japan Issues Tsunami Warning

The tremor, which occurred at a depth of 10 kilometers off the Sanriku coast, was strong enough to shake large buildings as far away as Tokyo.

Prime Minister Sanae Takaichi has established an emergency task force and urged citizens to seek higher ground immediately.

While an initial 80-centimeter tsunami was recorded at Kuji Port, authorities have warned of a slightly increased risk of a subsequent 'mega-quake' in the region.

No major damage or casualties were reported in the hours immediately following the initial jolt.
