Resumen:
A high-resolution early earthquake damage assessment system is presented
for Mexico City based on real-time computations of seismic spectral
intensities at a reference site. To obtain intensities for the entire
Mexico Valley, pre-calculated response spectral ratios at soft sites are
used. The estimates of seismic intensities (peak ground acceleration,
peak ground velocity and spectral ordinates for selected structural
periods), together with intensity-damage relations for buildings,
fatalities and water supply network were used to obtain the spatial
distribution of expected damage throughout the city. The process takes
approximately 10 minutes with no human intervention. Since the available
time to carry out all the computations is short, we have built a
representative building and population database that concentrates all
the information in a square mesh of 400 x 400 m. Results are sent to an
Emergency Center and to decision makers to trigger previously set
emergency plans and to provide information before emergency plans are in
full operation.
