Hobbies And Interests
Seismic Monitoring
Seismic monitoring is done with the use of a series of measuring devices placed at locations surrounding the volcano. The devices measure movement of the surface material which would indicate activity within the magma chambers below. Dependent on the size, frequency and direction of movement, volcanologists can impart important information about potential future activity.
Gas Studies
Gas studies are done with the use of sensor devices at locations on the surface where gas is being released from the magma chambers below. The devices usually measure the amount of sulphur being released, which can give an indication of the proximity of the magma to the earths surface. This then enables volcanologists to impart important information about the time of potential future activity.
Deformation Studies
Deformation studies perform a similar type of monitoring as seismic monitoring, however on a much more accurate scale. The devices used for deformation studies can detect surface movements as small as several millimeters. The detection of slight adjustments of the surface of the volcano could indicate activity within the magma chambers below. Appropriate action can then be taken.
Satellite Studies
Modern technology allows satellites to be used in order to measure surface movements. The precision of the imagery allows accurate interpretations of surface and underground activity to be made. This technique is often much safer due to the risk involved for individuals placing monitoring devices in other methods of detection highlighted above.
