style='font-size:10.0pt;font-family:Verdana'> As I spent about 8 years
living in <st1:country-region w:st="on"><st1:place w:st="on">Peru</st1:place></st1:country-region>, and
experienced a few severe earthquakes, there are a couple of basic aspects
of relevant "good" adobe building I would report.<br>
Many old constructions, as remote as colonial time, 3 or 4 centuries old,
stood well after all the sismic activity. Walls were built of adobe,
with a wonderful reinforcement of cane, thin bamboo, or split
bamboo . It worked with the same logic as rebar and concrete.<br>
Most churches, mansions, fencing tall walls, only showed minor
cracks after earthquakes.<br>
I saw a very old house in the center of <st1:City w:st="on"><st1:place
w:st="on">Lima</st1:place></st1:City>, that had some walls pulled down for
extension purposes, showing the long, hard and flexible strips
holding like a wide net the core of the adobe wall. The workers
had to take brick by brick, an saw each cane to release de digged trough
area. it took much more time than with simple adobe. <br>
as comparison, adobe houses built without vegetal fiber inner
netting , often fell down or had sever cracks after seism. <br>
Cane, and bamboo, are available in most places where ssmic ativity is a threat,
and seems more compatibele and efficient than metalic or plastic mesh, and is
obviously a better ecological option.<br>
