sorry but I don't know

Answer 2

Often the rescue from volcanic eruptions involves many a scientific tool and technique.  The most important of these include the the seismograph and the seismometer. Land deformity radars are also used in order to determine approximately in a probabilistic way the spot of the magma outlet. High tensile inextensible winch ropes are used to pull the surviving victims out using the MI 26 high utility winch holding copters. The COSPEC equipment is used.  The right spot of emergence of  volcanic gases is found using EDM leveling, tilt techniques . This is an overview of how a rescue is carried out from a volcanic catastrophe.
