El reci\u00e9n pasado 7 de diciembre obtuvo su grado de Doctorado en Ciencias de la Ingenier\u00eda nuestro estudiante Gerd Sielfeld, con la exitosa defensa de su tesis titulada “INTRA-ARC TECTONICS IN THE SOUTHERN ANDES: CONSTRAINTS FROM COMBINED FIELD GEOLOGY AND CRUSTAL SEISMICITY”.<\/p>\n

Abstract<\/h3>\n

En su tesis, Sielfeld investig\u00f3 sobre “la naturaleza de la deformaci\u00f3n cortical en ambientes volc\u00e1nicos. El trabajo se desarrolla en la regi\u00f3n de intra-arco de los Andes del Sur, combinado metodolog\u00edas de geolog\u00eda de campo y sismicidad natural; la primera para tener una perspectiva de la deformaci\u00f3n de largo plazo, la segunda, para estudiar la deformaci\u00f3n instant\u00e1nea asociada a fallas corticales. La coherencia en las observaciones de largo plazo y corto plazo indican que la volcanes se construyen en ambientes altamente fracturado, donde la herencia de fallas antiguas\u00a0 cumple\u00a0un rol fundamental en acomodar una fracci\u00f3n importante de la deformaci\u00f3n instant\u00e1nea derivada de la convergencia entre placas tect\u00f3nicas. Por otro lado, este estudio visualiza, que el espesor del medio fr\u00e1gil de la corteza, es menor en la regi\u00f3n volc\u00e1nica (intra-arco) donde hay un gradiente termal m\u00e1s elevado. De este modo, la tasa de deformaci\u00f3n es mayor en la regi\u00f3n de intra-arco, reflejada por la mayor tasa de sismicidad y consecuente preparaci\u00f3n estructural para la canalizaci\u00f3n de geofluidos. Esta contribuci\u00f3n abre nuevas interrogantes tanto en relaci\u00f3n a la exploraci\u00f3n de recursos geotermales as\u00ed como en la evaluaci\u00f3n de riesgo s\u00edsmico asociado a fallas corticales.”<\/p>\n
