VOLCANO-SEISMICITY OF LAKE VAN (EASTERN TURKEY): A COMPARATIVE ANALYSIS OF SEISMIC REFLECTION AND THREE- COMPONENT VELOCITY SEISMOGRAM DATA AND NEW INSIGHTS

seismic reflection, volcano-/tectono-magmatic activity, seismotectonic behavior, hybrid events, harmonic tremors. ABSTRACT This study presents a methodological and conceptual approach to effectively consider the Lake Van volcanic basin and its seismicity relationships by using seismic reflection and three-component velocity seismogram data. We used a couple of data set with high resolution geochirp and multi-channel seismic reflection data collected all over the Lake Van basin. Lake-wide seismicity analysis are reconsidered by spectral analysing of KOERI earthquake data, seismic waveforms at VANB broadband station. Thus, we improved the efficiency of our data set to understand and explain the volcano-related seismicity and advanced our inputs for greater output. We noted a new paradigm for earthquake anomalies of Lake Van volcanic basin by meaning seismic monitoring of volcanic systems, which are signals with certain fixed and distinct meanings. These signals are waveform patterns that are typical expressions of seismotectonic behavior of various magma chamber processes underneath the lake. The waveform patterns are key signs and a reliable measure of the volcano-seismic activity in the lake. The hybri
