Masonry built in seismic zones
must be carefully designed
especially if it's used in homes
the strain must be confined.
For if it's allowed to move sideways
(and catenary thrust will go lateral)
not if but when, on somber days
and falling walls can shatter all.
We've learned it before, and yet again
the danger of inadequate wall
thoughts and prayers do begin
for the people of Nepal.
