Seismic support

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.
