Abstract
Multifractal behaviour of interevent time sequences is investigated for the earthquake events in the NW Himalaya which is one of the most seismically active zones of India and experienced moderate to large damaging earthquakes in the past In the present study the multifractal detrended fluctuation analysis MFDFA is used to understand the multifractal behaviour of the earthquake data For this purpose a complete and homogeneous earthquake catalogue of the period 1965–2013 with a magnitude of completeness M w 43 is used The analysis revealed the presence of multifractal behaviour and sharp changes near the occurrence of three earthquakes of magnitude M w greater than 66 including the October 2005 Muzaffarabad–Kashmir earthquake The multifractal spectrum and related parameters are explored to understand the time dynamics and clustering of the eventsThe authors are thankful to their respective institutes for the support Authors thank to Prof VP Dimri for useful discussions AC acknowledges the support from the project HEARTPSC0203 for the study Authors are also thankful to the two anonymous reviewers for their suggestions to augment the manuscript to the present form
