Researchers from the University of Chile will lead national scientific cruise that will travel to the southern coast of the country

The 2018 Edition of the trajectory of the scientific "Cabo de Hornos" Navy ship will be extended between September 24 and October 18 between Puerto Montt and the Taitao Peninsula, enabling the development of innovative research on the seabed that is wait, are translated into the future in a better understanding of different geological phenomena in our country.

The possibility ofnew mineral reserves, deposits ofenergy resources,and studies ongeological hazardscauses, effects and probability of earthquakes are some of the subjects that will be studied in the 2018 campaign of the scientific Navy ship "Cape Horn", which for the first time will be led by geologico-marinas research.

Researchers from the Department of geology of the Faculty of physical sciences and mathematicsthey will participate in four of the seven projects that will take place during the cruise, between September 24 and October 18, an opportunity unprecedented for quality studies in a discipline where there is no national precedent.

"The relevance of these studies is that we can resolve several questions that today have no answers because while our country has four thousand kilometres of coastline and 200 miles from the sea,"This entire area is relatively little studied and know much of it,"said Professor Rodrigo Fernández, Department of geology, who is part of two research concursadas at the bottom center of instruction and maritime training (CIMAR), dependent of the General Directorate of the maritime territory and Merchant Navy (DIRECTEMAR).

The Director of the Department of geology and participating researcher of the expedition,Katja Deckart, described as excellent the possibility "to other less traditional geological area in Chile, as the marine geology. The 4,000 km of coast pose a great potential to study different aspects of the area near the coast, an excellent opportunity to change a little bit the course of traditional geology and also to attract students, because surely there will be topics of memories or other research academic, different to what we are accustomed".

With respect to the relevance of this type of research,Valentina Flores-researcher in the Department - and member of another initiative explained through the study of the sediment of the Seabed samples you will see the occurrence and recurrence of earthquakes of high magnitude. ""Despite being a seismic country, there is no information of the southern segment of the Valdivia earthquake rupture zone", just the area that we will explore, then this would allow us to see what so frequent are these types of earthquakes with prehistoric evidence in order to better understand these phenomena, their cycles and parameters".

The cruise CIMAR, organized by the National Oceanographic Committee (CONA) and hydrographic and oceanographic of the Armada de Chile (SHOA), takes place aboard the scientific vessel"Cabo de Hornos", one of the most modern cientifico-marina platforms of its kind today. It has autonomy for 35 days and up to 68 people, including 25 scientists. It's himunique scientific vessel built in Chile with capacity for work on geology and GEODESIC marinaincluding mapping and sampling of seabed and seismic survey.

The trip will take place in the waters of the outer continental shelf and inner sea, between Puerto Montt and the Taitao Peninsula, including the continental slope, submarine canyons, the triple point of plates and the Liquiñe-Ofqui fault zone.

Four projects with the participation of academics from the u. of Chile include "Neotectonics surface architecture and underwater paleosismologica in the area of fault Liquiñe-Ofqui (ZFLO) of the continental margin and the triple point Chilean: implications" for seismic hazard", of scholars Pascale Gregory, Daniel Moncada and Gabriel Vargas; "Occurrence and recurrence of earthquakes of high magnitude (Mw > 7.5) in the continental margin of Northern Patagonia during the Holocene (last 11,700 years)", Rodrigo Fernández, Valentina Flores, Tania Villaseñor and Maria Pia Rodriguez; "Mineralogical and geochemical study of the seabed between the island of Chiloé and the Taitao Peninsula for the characterization of mineral resources and evaluation of the potential of the economic exclusive zone of Chile", Marcelo Garcia (AMTC), Brian Townley, Katja Deckart and Daniel Moncada; and "Process modelers of submarine canyons and associated geologic hazards, in the segment of active continental margin between the Los Lagos and Aysén regions", Cristian Rodrigo (UNAB) and Rodrigo Fernández (geology-FCFM).
