Recent movements on the Cordillera Blanca fault (Peru)
 Sánchez Valdiviezo, Lisseth del Pilar ; Fischer, Tomáš (advisor) ; Burjánek, Jan (referee)
The studied area is located the Cordillera Blanca range (central Peru). This mountain range is, at its western foot, bordered by a 210 km long fault system bearing the same name. It is on this fault system where 3D monitoring of recent movements with the use of dilatometer TM-71 takes place. Displacements along this fault are analyzed with regard to the static stress changes caused by earthquakes. Moreover, processing and interpretation of data from ERT measurement performed across the investigated fault at Pitec locality (10 km from Huaraz) are presented. The resulting geoelectrical models of the measurement carried out in July 2016 at the mentioned locality indicate that this area is formed by rocks with very high resistivity values. It is a consequence of the presence of the moraine material (7 to 12 m thick) and of the base of the colluvial deposits composed of granites and granodiorites. At this site the fault has a dip angle of 70ř. The 3D displacement monitoring results of the studied fault at the Pitec locality indicate that the selected site is generally very stable. The dilatometer TM-71 has been in operation since 1997 and has been measuring movements on the Cordillera Blanca fault in all the three dimensions (perpendicular to the fault - opening, along the fault in horizontal plane,...

Seismic activity in Peru
 Sánchez Valdiviezo, Lisseth del Pilar ; Fischer, Tomáš (advisor) ; Jakoubková, Hana (referee)
This bachelor thesis approaches seismicity in Peru. It describes the origin of tectonic earthquakes and provides a general description of the basic concepts of seismology. This thesis work is mainly focused on a detailed characterization of seismic activity in Peru. It includes a complete description of the geodynamics of the Peruvian territory, the evolution and distribution of seismicity in this South American country and its geomorphological units.
