A recursive matched-filter to systematically explore a volcanic long-period earthquake swarm
… approach to systematically explore earthquake swarms, here applied to a swarm of volcanic long-period seismicity beneath Mount Sidley in Antarctica. We start with a single visually chosen template event with a high signal-to-noise ratio. We then extend our template database by …

Station Delays, Their Standard Deviations, and Event Relocations in the Reno-Area Basin from a Dense USArray Flexible Array Deployment during the 2008 West Reno Earthquake Swarm
… of ground motion. So from the point of earthquake hazard, it is important to know the basin geometry and its depth for the hazard evaluation of an area. Knowing the basin geometry and depth and velocity of sediments will enhance our understanding of ground amplification to improve …

Seismic tomography and surface deformation in Krýsuvík, SW Iceland
… energy that is currently experiencing seismic swarm activity and active surface deformation. Understanding the subsurface structure of the area is of great scientific and practical significance. Using permanent and temporary seismic stations deployed in the region, we captured an earthquake …

The Structural Analysis of Enola and Greenbrier, Arkansas Earthquake Swarms: Cause and Effect?
<p>Almost 20 years after the remarkable earthquake swarm of 1982, near the town of Enola, Arkansas, with more than 40,000 micro-earthquakes, another event revisited the same North-Central Arkansas region in 2001. Nine years later, in 2010, a huge swarm event shook the northern part of Faulkner …

Retrieval of earthquake source parameters in inhomogeneous anisotropic mediawith application to swarm events in West Bohemia in 2000
Earthquakes form by sudden brittle failure of rock mostly as shear ruptures along a rupture plane. Beside this, mechanisms other than pure shearing have been observed for some earthquakes mainly in volcanic areas. Possible explanations include complex rupture geometries and tensile earthquakes. …

Variations in structure and tectonics along the Mid-Atlantic Ridge, 23⁰N and 26⁰N
… the rift valley. In Chapters 3 and 4, the microearthquake characteristics and P wave velocity structure beneath the median valley of the Mid-Atlantic Ridge near 26°N are studied; this ridge segment is characterized by a large high-temperature hydrothermal field situated within the inner floor at …
