The Haven House, when situated
within liquefacting soil, is protected
from main earthquake forces due to the
dampening effect of the liquefacted soil
on seismic waves. The following
report* of a preliminary study by
Professor Radu Popescu from
Memorial University of Newfoundland
describes the research that Professor
Popescu conducted in order to assess
the validity of this statement. Note
particularly Figure 10 for a predicted
comparison of the seismic activity at
the base of the liquefacting material and
at the base and top of the Haven
House. Due to the properties of the
liquefacting soil and the ability of the
Haven House to float upon the
liquefacted soil, the earthquake forces
are generally dissipated. Also note
Figure 11 to see how the Haven
House, when in the throes of an
earthquake, resists rotational and
horizontal displacement.

| * It is mentioned that this preliminary study only analyzed one possible situation, involving a homogeneous liquefiable soil layer and assuming that the groundwater table was very close to the ground level. More investigations are necessary to assess the effects of soil heterogeneity, presence of denser soil, and deeper groundwater table. |
