The 26 January 2001 M 7.6 Bhuj, India, earthquake: Observed and predicted ground motions The 26 January 2001 M 7.6 Bhuj, India, earthquake: Observed and predicted ground motions
Although local and regional instrumental recordings of the devastating 26, January 2001, Bhuj earthquake are sparse, the distribution of macroseismic effects can provide important constraints on the mainshock ground motions. We compiled available news accounts describing damage and other effects and interpreted them to obtain modified Mercalli intensities (MMIs) at >200 locations...

Magnitude estimates of two large aftershocks of the 16 December 1811 New Madrid earthquake Magnitude estimates of two large aftershocks of the 16 December 1811 New Madrid earthquake
The three principal New Madrid mainshocks of 1811-1812 were followed by extensive aftershock sequences that included numerous felt events. Although no instrumental data are available for either the mainshocks or the aftershocks, available historical accounts do provide information that can be used to estimate magnitudes and locations for the large events. In this article we investigate...

Triggered earthquakes and the 1811-1812 New Madrid, central United States, earthquake sequence Triggered earthquakes and the 1811-1812 New Madrid, central United States, earthquake sequence
The 1811-1812 New Madrid, central United States, earthquake sequence included at least three events with magnitudes estimated at well above M 7.0. I discuss evidence that the sequence also produced at least three substantial triggered events well outside the New Madrid Seismic Zone, most likely in the vicinity of Cincinnati, Ohio. The largest of these events is estimated to have a...

Empirical Green's function analysis of recent moderate events in California Empirical Green's function analysis of recent moderate events in California
I use seismic data from portable digital stations and the broadband Terrascope network in southern California to investigate radiated earthquake source spectra and discuss the results in light of previous studies on both static stress drop and apparent stress. Applying the empirical Green's function (EGF) method to two sets of M 4-6.1 events, I obtain deconvolved source-spectra estimates...
