Gallery of Figures Fig. The real-time detection system is designed to display combined spectrograms based on two formed acoustic beams overlapping at preselected sites along the spreading center axis. Dark colors represent high acoustic power at a given time and frequency.
Shipping noise appears as parallel vertical lines.
The neovolcanic zone of the CoAxial segment is shown as a black line. The high relief of the volcanic rift zone may influence the location of epicenters.
