St. Kitts - Monitoring
Since 1957, Mt Liamuiga has been monitored continuously by a single short-period
seismograph1 station at Bayfords Farm, 8 km southeast of the crater. Geothermal
activity is also being monitored for changes in location, chemistry, temperature
and vigour. Ground deformation is monitored using a GPS2 network of 7 stations,
4 at the periphery, 2 on the flanks and one on the summit of Mt. Liamuiga.

1 Seismograph. A group of instruments used to record earthquakes.
A seismograph includes a seismometer as well as all equipment used to convert, transmit
and display the signals generated by the seismometer.
2 GPS. GPS stands for Global Positioning System. This is a geophysical
technique used to accurately determine the locations of specific points in three
dimensions. Very small (mm scale) changes in the locations of these points can be
recorded over time.
