摘要: Due to the sub-critical status of seismogenic crust, relatively small strain fluctuations (>0.1 strain) induced by post-seismic stress redistribution could significantly affect seismic hazard on a regional scale (tens thousands km) in medium-term (months tens years). The physical feasibility mud volcano monitoring for detection crustal field is discussed. Simple arguments are considered evaluate response volcanic system, terms liquid-outflow or gas discharge variations, slow pore pressure changes reservoir. application new remote sensing technique large-scale/medium-term also suggested.
