Since the 3/11 earthquake that
caused so much death and destruction, Japan has continued to
be hit by earthquakes that are large enough to send people
grabbing their emergency helmet that are under all the
desks. They're happening all the time, even if
they're not all felt in Tokyo, or by me.
For example, here's the USGS graphic for the earthquakes in
Japan just in the last day. The blue boxes are quakes
ranging from 4.6 to a 6.6.
Since I've been here, I've noted two that were large enough to
be moving things in my hotel room, or set buildings near the
office swaying visibly-
This 4.6 one on 9/11 rocked the bed and moved a book along the
floor.

This 6.2 one was felt at the office and was enough to make
waves in Tokyo Bay, sway buildings, and get us prepped to
evacuate. But it was short-lived. 90 miles away
from Tokyo.
