Objectives: a) To analyze the long-term seismicity and understand potential of seismic quiescence study to use it as a reliable precursor b) estimate B value variation in earthquake seismically active region. Methods: The present analyses pattern from Andaman- Sumatra region for period 1964 2018. area has been divided into epicentral blocks. Earthquakes preceding succeeding major with different...

Abstract. The region around the town Albstadt, SW Germany, was struck by four damaging earthquakes with magnitudes greater than 5 during last century. These occurred along Albstadt Shear Zone (ASZ), which is characterized more or less continuous microseismicity. As there are no visible surface ruptures that may be connected to fault zone, we study its characteristics seismicity distribution and...
