CATALOGUE OF FOCAL MECHANISMS OF PERUVIAN EARTHQUAKES ______________________________________________________________ H. TAVERA 2 ABSTRACT A way to know the orientation and to quantify the movement of tectonic plates and cortical faults, is studying the nature of faults related with the occurrence of great earthquakes. The orientation of the forces, which produce faults, gives us information to make the "Focal Mechanism", which solutions give important and relevant information in seismology studies, tectonics analysis and it is applicable in evaluation of Seismic Hazard. However, the values of these parameters appear in many scientific studies and technical reports without a uniform format. Also the issues have different assembly especially in the angle, which define the orientation of seismic fault in the source. Now a days there is no a compilation of focal mechanisms in Perú. The "Instituto Panamericano de Geografía e Historia" supports our desire to compile this information. The Focal Mechanisms Catalogue, join earthquakes with magnitudes great than 4.8 mb (from 1687) which has been subject matter of specially studies for many investigators. However our constrain is limited to bibliography information. This catalogue intends to be permanently updated with forthcoming data. CATALOGUE OF FOCAL MECHANISMS OF PERUVIAN EARTHQUAKES ______________________________________________________________ H. TAVERA 3 RESUMEN Una manera de conocer la orientación y cuantificar el movimiento de las placas tectónicas o de los fracturamientos corticales, es estudiando la naturaleza de las fracturas asociadas a la producción de grandes terremotos. La orientación de las fuerzas que generan una ruptura, permiten configurar los denominados "Mecanismos Focales", cuyas soluciones proveen de información necesaria para estudios en Sismología, Análisis Tectónicos y son posibles de aplicarse en la evaluación del Peligro y Riesgo Sísmico. Sin embargo, los valores de estos parámetros son presentados en diferentes estudios científicos y reportes técnicos, sin existir un compendio único al cual se pueda consultar. Además, se suma a esta dificultad, el que los resultados sean presentados con diferentes convenciones, especialmente los relacionados a los ángulos que definen la orientación del fracturamiento en la fuente sísmica. Para el Perú, a la fecha no existe ninguna compilación de Mecanismos Focales. Para llenar este vacio, el Instituto Panamericano de Geografía e Historia apoyó la iniciativa del autor, de presentar a consideración de la comunidad científica este Catálogo de Mecanismos Focales, el cual agrupa a los sismos con magnitudes mayores a 4.8 mb desde 1687 a la fecha, que han sido objeto de estudio de muchos investigadores. Sin embargo, los autores se han visto limitados en cuanto a información bibliográfica se refiere; por lo que, de producirse la publicación de nuevos estudios, estos serán dados a conocer en una nueva edición.

TAVERA 5 CATALOGUE OF FOCAL MECHANISMS OF PERUVIAN EARTHQUAKES Hernando Tavera I. INTRODUCTION The occidental border of South America is one of the most seismic regions of the world. The Perú belong of this region and its seismicity will be divided in two groups: the first is the most important and is related with subduction of Nazca plate below continental plate. This activity is really 90% of total annual seismic energy more frequent and of great magnitude. The second group is related with seismicity generated by cortical deformations and it is associated to technical fault in Perú (system faults of Tambomachay, Satipo-Moyobamba, Cordillera Blanca, Huaytapallana, Quiches, etc.). This seismic activity is not frequent and with moderate magnitude. After 1960, seismicity studies increase in Perú and were developed by foreign scientists; the most important study was developed by Barazangi and Isacks (1976) which configure the subduction zone from Ecuador to North of Chile they used depth seismicity distribution. By the other hand the studies of CATALOGUE OF FOCAL MECHANISMS OF PERUVIAN EARTHQUAKES ______________________________________________________________ H. TAVERA 6 Stauder and Bollinger (1964-65) and Stauder (1975) were the first beginnings of analyses stresses distribution in Perú. Subsequently this work was development by peruvian scientist, but only for regional zones or important earthquakes. In the catalogue of this paper, we show some solutions of focal mechanisms for the same earthquake from original publications. The solution of focal mechanisms was obtained using the direction of the first movement of P and/or PKP waves. In some cases the data of P wave is completed with S wave, considering the polarization angle or the direction of first movement of SV in SH components. Recently some earthquakes were studied using other methods like Centroid Moment Tensor (CMT) or using the volume and surface waves’ inversion. These CMT solutions are not considerate in present catalogue because we do not have bibliographic information. A way to represent the mechanism of an earthquake is defined by a shear fault of plane surface which dimensions are little in contrast with the distance of the observation point and with the longitude of wave of determination observations used. Geometrical parameters which define fault orientation are strike of trace, dip and slip direction. These parameters are obtained using elastic displacements generated by the event and are detected in seismic stations (seismograms). The solution of focal mechanism (fault plane), assume polarity of P waves (signal and sense of first movement) registered in the stations around the world, and plotted them into a focal sphere separated by two ortogonals planes in four quadrants. The models equivalents to forces in seismic focus are like to a simple or double couple forces. The model of double couple is equivalent to "pure shear displacement dislocations", which explain the nature of big earthquake generation. The area selected for recompilation of seismic events, which belongs to this catalogue is limited between 0° to 19° south latitude and between 68° to 85° west longitude. The catalogue is limited in total solutions about focal mechanism CATALOGUE OF FOCAL MECHANISMS OF PERUVIAN EARTHQUAKES ______________________________________________________________ H.

TAVERA 10 III. - SEISMICITY AND STRESS DISTRIBUTION The regional stress orientation is frequently used to know the forces of crustal earth (Mendiguren, 1971; Bergman & Solomon, 1980). The variety of stress in lithosphere is related of many forces generated by local sources (heterogeneous structure, thermal anomalies in asthenosphere, etc.) and regional movements of plates (subduction process and plate’s expansion, etc). From these sources the last play the most important roll in dynamic process of lithosphere. By the other hand, is important to know some indicators of orientation (seismic parameters measures in situ of stress in geological faults) forces in big areas interplate and intraplate. The focal mechanisms of important events are used generally to infer stress regional orientations (Richardson et al. 1979; Bergman & Solomon, 1984). A great numbers of seismic events are necessary to know patterns of regional stress in interplate’s zones (subduction zones) and intraplates zones (reactivation of geological faults). In the case of stress related to great earthquakes, are important the pressure (P) and tension (T) axes related to solutions of faults planes. In west side of american continent the interplate earthquakes show the pressure axes (P) in E-W direction for this reason Stauder (1975), Suárez et al. (1983), Chinn and Isacks, (1983) y Assumpçâo & Suárez (1988) affirm the presence of compressional forces generated for collision of Nazca plate an sudamericana plate. This horizontal compression generate important gravitationals effects in andean topography, this fact would explain the presence of extensional forces in N-S direction (interplate earthquakes) in Perú and Bolivia andes (Sébrier et al., 1985, 1988). CATALOGUE OF FOCAL MECHANISMS OF PERUVIAN EARTHQUAKES ______________________________________________________________ H. TAVERA 11 All seismic activity of Perú shows us the active state of principal seismotectonic zones (interplate, subduction zones; intraplate, faults actives) as constant liberation energy (earthquakes). The study of these seismic events (magnitude great 4.8 mb) individually or in set gives the distribution of movements and displacement in seismic source. Many studies have been elaborated to explain lithosphere dynamics in Perú, some of the most important were development by: Mendiguren (1966), Isacks & Molnar (1971), Tellería (1971), et al (1983), Froidevaux & Isacks (1984), Sébrier et al (1985,1988), Carey- Gailhardis & Mercier (1987), Assumpçâo & Suárez (1988) y Assumpçâo (1990,1991). The results obtained in these studies let us to get an idea about all seismic energy generated in American continent. CATALOGUE OF FOCAL MECHANISMS OF PERUVIAN EARTHQUAKES ______________________________________________________________ H. TAVERA 12 CATALOGO DE MECANISMOS FOCALES PARA TERREMOTOS PERUANOS Hernando Tavera I. INTRODUCCION El borde Occidental de América del Sur, se caracteriza por ser una de las regiones sísmicamente más activas del mundo. El Perú, forma parte de esta región, y su sismicidad puede ser dividida en dos grupos: el primero y el más importante, esta relacionado con la sismicidad asociada al proceso de subducción de la Placa de Nazca por debajo de la Placa Continental. Esta actividad, libera aproximadamente el 90% del total de la energía sísmica anual, siendo generalmente más frecuente y de grandes magnitudes. El segundo grupo, considera a la sismicidad producida por las deformaciones corticales y esta asociada a los fallamientos tectónicamente activos existentes en el Perú. Por ejemplo: sistema de fallamientos de Tambomachay, Satipo-Moyobamba, Cordillera Blanca, Huaytapallana, Quiches, etc. Esta actividad sísmica es menos frecuente y de magnitudes moderadas. Después de los años 60, los estudios de sismicidad se incrementaron en el Perú y fueron desarrollados principalmente por científicos extranjeros. El estudio más importante, fue el realizado por Barazangi & Isacks (1976), que llegaron a configurar la zona de subducción desde el Ecuador hasta el CATALOGUE OF FOCAL MECHANISMS OF PERUVIAN EARTHQUAKES ______________________________________________________________ H. TAVERA 13 Norte de Chile, a partir de la distribución de la sismicidad en profundidad. En lo referente a estudios sobre mecanismos focales, los trabajos realizados por Stauder & Bollinger (1964- 65) y Stauder (1975) iniciaron el camino al análisis de la distribución de esfuerzos en el Perú. Posteriormente, esta labor fue complementada por investigadores peruanos, pero únicamente para zonas de interés regional o para sismos importantes. En este catálogo, se presenta una o varias soluciones del mecanismo focal obtenido para un mismo terremoto, compilado a partir de publicaciones originales. La solución de los mecanismos focales, fue obtenida generalmente utilizando la dirección del primer movimiento de las ondas P y/o PKP. En algunos casos, los datos de la onda P son complementados con los de las ondas S, considerando su ángulo de polarización o el sentido del primer movimiento de sus componentes SV y SH. Recientemente, algunos terremotos fueron estudiados utilizando la metodología del modelamiento e inversión de ondas de volumen y superfiales. Asimismo, el Observatorio de Harvard publica en el "Earthquake Data Reports" de la U.S. Geological Survey, las soluciones de los mecanismos de algunos terremotos usando el método del Centroid-Moment-Tensor. Estas soluciones, no han sido consideradas en el presente catálogo. Una manera de representar el mecanismo de un terremoto, es el de una fractura de cizalla de supeficie plana y cuyas dimensiones son pequeñas comparadas con la distancia al punto de observación, y con la longitud de onda de las observaciones empleadas en su determinación. Los parámetros geométricos que definen la orientación de una falla son el azimut de su traza, el buzamiento del plano y la dirección del deslizamiento que ha tenido lugar. El cálculo de estos parámetros se realiza a partir del campo de desplazamientos elásticos producidos por el sismo. Estos desplazamientos son observados en los sismogramas registrados en las estaciones distribuidas sobre la superficie de la tierra. CATALOGUE OF FOCAL MECHANISMS OF PERUVIAN EARTHQUAKES ______________________________________________________________ H. TAVERA 14 La definición de solución del mecanismo focal (planos de falla), asume la polaridad de las ondas P (sentido del primer movimiento) registradas en las estaciones mundiales, las mismas que son distribuidas sobre una esfera focal y separadas por dos planos ortogonales en cuatro cuadrantes. Los modelos equivalentes a las fuerzas que actúan en el foco sísmico, corresponden a un sistema de simple o de doble par de fuerzas. El modelo de doble par, es equivalente a "pure shear displacement dislocation", el mismo que explica la naturaleza de la generación de grandes terremotos. El área seleccionada para la recopilación de los eventos sísmicos, que forman parte de este Catálogo, se encuentra entre 0° a 19° Latitud Sur y 67° a 85° Longitud Oeste. El catálogo, esta limitado al total de soluciones que sobre mecanismos focales se han elaborado para terremotos ocurridos en el Perú y areas vecinas a la fecha y que han sido publicados en trabajos científicos o informes técnicos. Preliminarmente, se presenta un total de 116 eventos sísmicos, los mismos que posteriormente pueden ser complementados en una nueva edición. La relación de los eventos considerados en el presente catálogo, está indicada en la Tabla 1 y su distribución geográfica en las Figuras 1, 2 y 3: superficiales, intermedias y profundas.

CATALOGUE OF FOCAL MECHANISMS OF PERUVIAN EARTHQUAKES ______________________________________________________________ H. TAVERA 18 III.- SISMICIDAD Y DISTRIBUCION DE ESFUERZOS La orientación de los esfuerzos regionales en la litósfera es frecuentemente utilizado para inferir las fuerzas que causan el movimiento de la corteza terrestre (Mendiguren, 1971; Bergman & Solomon, 1980). La diversidad de esfuerzos en la litósfera, es debida a la presencia de diferentes fuerzas causadas por fuentes locales (estructuras heterogéneas, anomalías termales en la astenósfera, etc), y regionales o movimiento de las placas (procesos de subducción y expansión de placas, etc). De estas fuentes, la última juega el rol más importante en el proceso dinámico de la litósfera. Por otro lado, es importante conocer algunos indicadores de la orientación de estas fuerzas (parámetros sísmicos, medidas "in situ" de esfuerzos observados sobre fallas geológicas) sobre grandes áreas interplaca e intraplaca. Los mecanismos focales de sismos importantes, son comúnmente usados para inferir la orientación de los esfuerzos tectónicos regionales (Richardson et al. 1979; Bergman & Solomon, 1984). Un gran número de eventos sísmicos son necesarios para establecer patrones de esfuerzos regionales en zonas interplacas (zonas de subducción) y en zonas intraplacas (formación o reactivación de fallas geológicas). En el caso de los esfuerzos relacionados a los grandes sismos, son importantes los ejes de Presión (P) y Tensión (T) relacionados a la solución de los planos de falla. En el flanco oeste del continente sudamericano, los sismos interplaca generalmente presentan el eje de Presión (P) orientado en la dirección E-W, por lo que Stauder (1975), Suárez et al. (1983), Chinn & Isacks, (1983) y Assumpçâo & Suárez (1988) atribuyen la presencia de fuerzas compresionales causados por la colisión de la placa de Nazca y la placa Sudamericana. CATALOGUE OF FOCAL MECHANISMS OF PERUVIAN EARTHQUAKES ______________________________________________________________ H. TAVERA 19 Esta compresión horizontal, ha generado importantes efectos gravitacionales en la topografía andina, hecho que explicaría la presencia de fuerzas extensivas orientadas en la dirección N-S (sismos intraplaca) en los altos andes de Perú y Bolivia (Sébrier et al., 1985,1988). La totalidad de la actividad sísmica que se produce en el Perú pone de manifiesto el caracter activo de las principales zonas sismotectónicas (interplaca, zona de subducción; intraplaca, fallas activas) a partir de la constante liberación de energía a manera de sismos. El estudio de estos eventos sísmicos (magnitudes mayores a 4.8 mb), ya sea de manera individual o en conjunto permite conocer la distribución de los principales esfuerzos que gobiernan los movimientos o desplazamientos producidos en la fuente o foco sísmico. Muchos estudios han sido ya elaborados para explicar la dinámica de la litósfera en el Perú, siendo los más importantes los desarrollados por: Mendiguren (1966), Isacks & Molnar (1971), Tellería (1971), et al (1983), Froidevaux & Isacks (1984), Sébrier et al (1985,1988), Carey-Gailhardis & Mercier (1987), Assumpçâo & Suárez (1988) y Assumpçâo (1990,1991). Con los resultados obtenidos de estos estudios, se puede tener idea del total de la energía que se libera en esta parte del continente americano.
