The maximum displacement was 2.5 m with a maximum vertical motion about 60 cm at Playa Sa Juanillo (OVSICORI Report on September 11 th , 2012). The fault displacement continued until the end of September through postseismic motions, slow earthquakes, viscoelastic response and aftershocks (> 2500 during the first 10 days following the Nicoya earthquake). The seismicity spread to most of the country (Fig.1) Figure 1: Seismicity in September 2012 and location of the main volcanoes. Yellow star: epicenter of the Nicoya seism on September 5 th , 2012 (Mw = 7.6). White arrow: direction of the displacement due to the Nicoya seism (map: Walter Jiménez Urrutia, Evelyn Núñez, y Floribeth Vega del grupo de sismología del OVSICORI-UNA). Regarding the volcanoes, the seism of Nicoya generated an important seismic activity especially in the volcanic complexes Irazú-Turrialba and Poás as well as an unusual seismic activity mainly for Miravalles, Tenorio and Platanar-Porvenir. -

Desarrollo De La Energía Geotérmica En Costa Rica
Presented at Short Course on Geothermal Development in Central America – Resource Assessment and Environmental Management, organized by UNU-GTP and LaGeo, in San Salvador, El Salvador, 25 November – 1 December, 2007. GEOTHERMAL TRAINING PROGRAMME LaGeo S.A. de C.V. ASSESSMENT AND DEVELOPMENT OF THE GEOTHERMAL ENERGY RESOURCES OF COSTA RICA Paul Moya1 and Antonio Yock2 Instituto Costarricense de Electricidad, UEN Proyectos y Servicios Asociados C. S. Recursos Geotérmicos, Apartado Postal 10032-1000 San José COSTA RICA [email protected], [email protected]. ABSTRACT The assessment and development of geothermal energy resources in Costa Rica and their contribution to the electricity needs of the nation are reviewed. A national reconnaissance resource study, carried out during 1989 and 1991 (ICE, 1991), indicated that the possible total geothermal potential of the country was about 900 MWe. The first deep geothermal exploratory wells in Costa Rica were drilled at the Miravalles geothermal field in 1979-1980. The good results obtained in these wells allowed ICE to proceed to study the possibility of installing a geothermal power plant of 55 MW (Unit 1). Electricity was first generated at the Miravalles field in early 1994. Since then, the installed capacity has grown from 55 MWe (1994) to 163 MWe (2007). The two undeveloped Costa Rican geothermal systems that have been studied the most are those associated with the Tenorio and Rincón de la Vieja volcanoes. In 2001, a deep exploratory drilling program was begun at the Las Pailas geothermal zone on the southern slope of the Rincón de la Vieja volcano. At the same volcano, but in another geothermal zone called Borinquen, geothermal wells have been drilled starting in 2003 and 2004. -
The Geothermal Resource in the Guanacaste Region (Costa Rica): New Hints from the Geochemistry of Naturally Discharging Fluids

Lowenstern, Tenorio was previously interpreted as due to a north-to-south general flow of thermal Cascades Volcano Observatory waters and a magmatic gas upwelling mostly centered at Rincón de la Vieja, whereas (CVO), Volcano Disaster Assistance Program (USGS), United States Miravalles volcano was regarded as fed by a typical geothermal reservoir consisting Reviewed by: of a highly saline Na-Cl aquifer.

3D Density Modeling of the Central American Isthmus from Satellite
3D Density Modeling of the Central American Isthmus from Satellite Derived Gravity Data Dissertation zur Erlangung des Doktorgrades "Dr. rer. nat." der Mathematisch-Naturwissenschaftlichen Fakultät der Christian-Albrechts-Universität zu Kiel vorgelegt von Oscar H. Lücke Institut für Geowissenschaften, Abteilung Geophysik Kiel, 2012 Erstgutachter: Prof. Dr. Hans-Jürgen Götze Zweitgutachter: Prof. Dr. Wolfgang Rabbel Tag der mündlichen Prüfung: 21. August, 2012. gez. Prof. Dr. Lutz Kipp, Dekan i Abstract The combined geopotential models based on satellite and surface gravity data provide a homogenous gravity database with near global coverage. In this work, the data from the EGM2008 Combined Geopotential Model has been interpreted to prepare a comprehensive three dimensional model of the lithospheric density structure along the Central American Isthmus. The main focus of the model is the interpretation of the subduction process along the Middle American Trench and the segmentation of the oceanic Cocos and Nazca plates and the overriding Caribbean Plate. The viability of the EGM2008 data as input for the forward modeling has been assessed in terms of resolution and consistency with surface gravity data. For this purpose, a detailed surface gravity database was compiled and homogenized for Costa Rica and then compared with a subset of different data products from EGM2008. The Bouguer anomaly calculated from the gravity disturbance (geophysical anomaly) was determined to be the most consistent with the anomalies obtained from the surface stations, particularly in areas of high topography. The analysis also determined the areas in which the lower wavelengths from EGM2008 were dependent on the existence of surface gravity stations and the areas in which fill-in data may have been used to achieve its maximum spatial resolution. -
