| Abstract | There a.re two different opinions a.bout seismicity of North Vietnrun. The
first is: North Vietnam has a very low seismicity. The second one is: being
situated at the cross of the two most seismically active belts of the world,
North Vietnam represents a seismic hazard area.
Being among those who support the latter op1n1on, the author of this
research, once again, provides an example to assert his idea through an
attempt of quantitative assessment of seismic hazard of North Vietnam.
After taking into account all the data available for the North Vietnam:
distribution of seismic events, seismotectonic, structural characteristics and
geophysical data, the studied area was divided into five seismic source zones.
Each zone was investigated in details about its sei smicity as well as other
f eatures like: the potential depth of occurrence, the maximum potential
ma.gn i tude .. .
The main r esults of this study are a set of 8 seismic zoning maps which
provide peak ground motion (acceleration, velocity, displacement, and duration
of oscillation) for two values of probability of exceedence: P=86% and P=63%
(with time of exposure t=90 years) equivalent to return periods of 45 years
and 90 years respectively for North Vietnam. Those maps allow us not only to
draw some important conclusions on seismicity of North Vietnam as a whole and
of each zone, but they can also be served directly to develop counterearthquake
design parameters. |
