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...

The 1998 earthquake sequence south of Long Valley Caldera, California: Hints of magmatic involvement The 1998 earthquake sequence south of Long Valley Caldera, California: Hints of magmatic involvement
A significant episode of seismic and geodetic unrest took place at Long Valley Caldera, California, beginning in the summer of 1997. Activity through late May of 1998 was concentrated in and around the south moat and the south margin of the resurgent dome. The Sierran Nevada block (SNB) region to the south/southeast remained relatively quiet until a M 5.1 event occurred there on 9 June...

A volcano in North Carolina? A closer look at a tall tale A volcano in North Carolina? A closer look at a tall tale
The legacy of the 1811-1812 New Madrid, Central United States, earthquakes is one of tremendous enigma. We are left with just enough contemporary information to provide a measure of constraint on the isoseismal contours and therefore magnitudes of the three principal events (Nuttli, 1973; Street, 1982; Johnston, 1996; Hough et al., 2000), yet given the sparse population density and...

On the modified Mercalli intensities and magnitudes of the 1811-1812 New Madrid earthquakes On the modified Mercalli intensities and magnitudes of the 1811-1812 New Madrid earthquakes
We reexamine original felt reports from the 1811–1812 New Madrid earthquakes and determine revised isoseismal maps for the three principal mainshocks. In many cases we interpret lower values than those assigned by earlier studies. In some cases the revisions result from an interpretation of original felt reports with an appreciation for site response issues. Additionally, earlier studies...
