Earthquake Relocation And Focal Mechanism Analysis In The Area Of Rupture Following The Mw = 7.6 September 5 2012 Nicoya Earthquake Costa Rica, Gregory Brenn Jun 2014

Earthquake Relocation And Focal Mechanism Analysis In The Area Of Rupture Following The Mw = 7.6 September 5 2012 Nicoya Earthquake Costa Rica, Gregory Brenn

Honors Theses

As part of a Keck Geology Consortium project on the Nicoya Peninsula, Costa Rica, a dense broadband seismic array was installed directly above the rupture zone of the long-anticipated Nicoya September 5th, 2012, Mw= 7.6 earthquake. 5 Nanometrics Trillium compact seismometers and Taurus digitizers were installed, defining a ~200km triangular area with one triangular side oriented parallel to the trench and the apex located ~15km inland from the coast. This seismic network was operating from July 2nd to July 18th, and with this data combined with the permanent stations of the Nicoya broadband network, 254 events were initially located. Comparison …


Correlating Monotonous Crystal-Rich Dacitic Ignimbrites In Dominica: The Layou And Roseau Ignimbrite, Alexandra Flake Jun 2014

Correlating Monotonous Crystal-Rich Dacitic Ignimbrites In Dominica: The Layou And Roseau Ignimbrite, Alexandra Flake

Honors Theses

Dominica is a small island in the Lesser Antilles island arc. It has the highest concentrations of potentially active volcanoes in the world and features several large Pleistocene pyroclastic deposits that extend to the sea. Two of the ignimbrites emanate from central Dominica, with pyroclastic deposits filling the Layou and Roseau river valleys. Based on topography, the Layou Ignimbrite is believed to be from Morne Trois Pitons, whereas the Roseau Ignimbrite is derived from vents in the Wotten Waven region. On the coast in the village of Layou, the Layou Ignimbrite is 13 m thick with a basal large block …
