Abstract

In this work we analyze the kinematics of the Alhama de Murcia Fault in the area of Lorca-Totana, from Upper Pliocene to Presento In this analysis we make use of the information given by pliocene and quaternary sediments. An alternance of thrust and sinistral kinematics behaviours of the Alhama de Murcia Fault can be recognized. This behaviours broungt about for two shortering directions: NNE-SSO and NNO-SSE that control the structure and evolution of Guadalentin Basin and recent sediments. We also study the disposition of more significative earthquakes and its relations with principal shears. The Alhama de Murcia Fault control parcially that disposition and the kind of earthquakes.

Highlights

  • In this work we analyze the kinematics of the Alhama de Murcia Fault in the area of Lorca-Totana, from Upper Pliocene to Presento In this analysis we make use of the information given by pliocene and quaternary sediments

  • Evitamos así las complejidades introducidas en la estructuración de los materiales miocenos por estadios comprensivos prepliocenos

  • En el sector Lorca-Totana la sismicidad parece acumularse en los extremos del corredor, coincidiendo con sendos cambios en la dirección de la traza principal de la Falla de Alhama de Murcia

Summary

Introduction

In this work we analyze the kinematics of the Alhama de Murcia Fault in the area of Lorca-Totana, from Upper Pliocene to Presento In this analysis we make use of the information given by pliocene and quaternary sediments. El sector aquí estudadio de la Falla de Alhama de Murcia está conformada por dos corredores de cizallamiento, aproximadamente paralelos con una dirección N 50-65 E, a los que hemos denominado: Corredor Norte de Lorca (CNLj y Corredor Sur de Lorca (CSL)
