We only hear about the ones without damage, what about the psychological impact?

While the absence of a tsunami is a huge relief, this constant seismic activity must be incredibly stressful for the local population.

Japan's preparedness is top-notch, yet this event still serves as a stark reminder of the ever-present danger they live with daily.

The quick confirmation of no tsunami is positive, however, the shallow depth of the quake could have caused more significant local shaking.
