Ambient Seismic Noise Analysis Associated with the 2010 Eruption of Merapi Volcano Using Temporal Variations of Randomness and Background Noise

<div>Comparison of the frequency response of Mark L-22/2 Hz, Mark L-4C/1 Hz, Güralp CMG-3ESP/30s, and Güralp CMG-40T/30s seismometers. Both short-period seismometers (Mark L-22/2s and Mark L4C/1s) have limitations in responding to low-frequency events (&lt;1 Hz) compared to both broadband seismometer (Güralp CMG-3ESP/30s and Güralp CMG-40T/30s).</div>
