Seismic zonation of Port-Au-Prince using pixel- and object-based imaging analysis methods on ASTER GDEM Seismic zonation of Port-Au-Prince using pixel- and object-based imaging analysis methods on ASTER GDEM
We report about a preliminary study to evaluate the use of semi-automated imaging analysis of remotely-sensed DEM and field geophysical measurements to develop a seismic-zonation map of Port-au-Prince, Haiti. For in situ data, VS30 values are derived from the MASW technique deployed in and around the city. For satellite imagery, we use an ASTER GDEM of Hispaniola. We apply both pixel-...

Strong ground motion in Port-au-Prince, Haiti, during the M7.0 12 January 2010 Haiti earthquake Strong ground motion in Port-au-Prince, Haiti, during the M7.0 12 January 2010 Haiti earthquake
No strong motion records are available for the 12 January 2010 M7.0 Haiti earthquake. We use aftershock recordings as well as detailed considerations of damage to estimate the severity and distribution of mainshock shaking in Port-au-Prince. Relative to ground motions at a hard - rock reference site, peak accelerations are amplified by a factor of approximately 2 at sites on low-lying...

Toward a consistent model for strain accrual and release for the New Madrid Seismic Zone, central United States Toward a consistent model for strain accrual and release for the New Madrid Seismic Zone, central United States
At the heart of the conundrum of seismogenesis in the New Madrid Seismic Zone is the apparently substantial discrepancy between low strain rate and high recent seismic moment release. In this study we revisit the magnitudes of the four principal 1811–1812 earthquakes using intensity values determined from individual assessments from four experts. Using these values and the grid search...

Localized damage associated with topographic amplification during the 12 January 2010 M 7.0 Haiti earthquake Localized damage associated with topographic amplification during the 12 January 2010 M 7.0 Haiti earthquake
Local geological conditions, including both near-surface sedimentary layers1,2,3,4 and topographic features5,6,7,8,9, are known to significantly influence ground motions caused by earthquakes. Microzonation maps use local geological conditions to characterize seismic hazard, but commonly incorporate the effect of only sedimentary layers10,11,12. Microzonation does not take into account...

Intensity, magnitude, location and attenuation in India for felt earthquakes since 1762 Intensity, magnitude, location and attenuation in India for felt earthquakes since 1762
A comprehensive, consistently interpreted new catalog of felt intensities for India (Martin and Szeliga, 2010, this issue) includes intensities for 570 earthquakes; instrumental magnitudes and locations are available for 100 of these events. We use the intensity values for 29 of the instrumentally recorded events to develop new intensity versus attenuation relations for the Indian...

The crowbar chronicles and other tales The crowbar chronicles and other tales
The analysis of historical earthquakes often relies heavily on archival accounts describing the effects of shaking on structures and people. Newspaper articles are among the most common, useful, and easily found sources of information. Dramatic earthquake effects are almost certain to have made the news during historic times; the challenge for modern seismologists is not to be overly...
