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...

The 1170 and 1202 CE Dead Sea Rift earthquakes and long-term magnitude distribution of the Dead Sea Fault zone The 1170 and 1202 CE Dead Sea Rift earthquakes and long-term magnitude distribution of the Dead Sea Fault zone
In combination with the historical record, paleoseismic investigations have provided a record of large earthquakes in the Dead Sea Rift that extends back over 1500 years. Analysis of macroseismic effects can help refine magnitude estimates for large historical events. In this study we consider the detailed intensity distributions for two large events, in 1170 CE and 1202 CE, as...

Cataloging the 1811-1812 New Madrid, central U.S., earthquake sequence Cataloging the 1811-1812 New Madrid, central U.S., earthquake sequence
The three principal New Madrid, central U.S., mainshocks of 1811-1812 were followed by extensive aftershock sequences that included numerous felt events. Although no instrumental data are available for the sequence, historical accounts provide information that can be used to estimate magnitudes and locations for the large aftershocks as well as the mainshocks. Several detailed eyewitness...

Comments on potential geologic and seismic hazards affecting proposed liquefied natural gas site in Santa Monica Bay, California Comments on potential geologic and seismic hazards affecting proposed liquefied natural gas site in Santa Monica Bay, California
In a letter to the U.S. Geological Survey (USGS) dated March 25, 2008, Representative Jane Harman (California 36th district) requested advice on geologic hazards that should be considered in the review of a proposed liquefied natural gas (LNG) facility off the California coast in Santa Monica Bay. In 2004, the USGS responded to a similar request from Representative Lois Capps, regarding...
