Tectonic earthquake swarms in the Northern Volcanic Zone, Iceland
… including fore- and aftershocks to destructive earthquakes on large faults, magma movement at volcanoes, or the gradual advance of glaciers. Microearthquakes at faults might also signal more exotic behaviour, including due to transient events such as fluid injections or pulses of aseismic fault …

A study of seismicity and earthquake swarms in the Central Mediterranean
… region during the last 7 years (1996 -2002). 118 earthquakes recorded at Wied Dalam Broadband seismic station, Malta, have been studied and the magnitude-frequency statistics were calculated for the whole region. Occurrence of earthquake swarms has been observed in the data. This swarm activity …

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 …

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 …

Controls on earthquake rupture and triggering mechanisms in subduction zones
Large earthquake rupture and triggering mechanisms that drive seismicity in subduction zones are investigated in this thesis using a combination of earthquake observations, statistical and physical modeling. A comparison of the rupture characteristics of M ≥ 7.5 earthquakes with fore-arc geological …

Investigations of Anomalous Earthquakes at Active Volcanoes
… unrest and the occurrence of moderate-to-large earthquakes with a specific type of focal mechanism. Vertical compensated-linear-vector-dipole (vertical-CLVD) earthquakes have vertical pressure or tension axes and seismic radiation patterns that are inconsistent with the double-couple model of …

Source array and receiver array analysis of Vogtland/ West Bohemia earthquake clusters
Die Region Vogtland/ West Böhmen im Grenzgebiet zwischen Deutschland und Tschechien ist bekannt für ihre geologische Aktivität. Holozäner Vulkanismus, Gasaustritte an Mofetten und Quellen und wiederkehrende Erdbebenschwärme sind Ausdruck geodynamischer Prozesse im Untergrund. Während des …

Statistical analysis of natural and induced seismicity catalogues
Hlavním cílem této práce je analýza statistických vlastností přírodních a indukovaných seismických katalogů. Porovnáváme časové a magnitudové vlastnosti různých druhů zemětřesných katalogů a hledáme jejich podobnosti a odlišnosti. Na deset různých seismických katalogů přírodního a indukovaného …
