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...

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...

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...

Attenuation and source properties at the Coso Geothermal area, California Attenuation and source properties at the Coso Geothermal area, California
We use a multiple-empirical Green's function method to determine source properties of small (M −0.4 to 1.3) earthquakes and P- and S-wave attenuation at the Coso Geothermal Field, California. Source properties of a previously identified set of clustered events from the Coso geothermal region are first analyzed using an empirical Green's function (EGF) method. Stress-drop values of at...

The Loma Prieta, California, earthquake of October 17, 1989: Aftershocks and postseismic effects The Loma Prieta, California, earthquake of October 17, 1989: Aftershocks and postseismic effects
While the damaging effects of the earthquake represent a significant social setback and economic loss, the geophysical effects have produced a wealth of data that have provided important insights into the structure and mechanics of the San Andreas Fault system. Generally, the period after a large earthquake is vitally important to monitor. During this part of the seismic cycle, the...
