Abstract

The thermal activity of a seismically active area in Central Asia has been monitored remotely and with in situ sensors. The remote sensing in the 8 to 14 micron region was made using the NOAA series satellites AVHRR-2 and HCMM radiometers, with temperature sensitivity of 0.5 K. The surface thermal effects were of the order of 3 to 5 K. These temperature anomalies associated with the Kopet-Dag, Karatau and other deep faults which are the source of seismicity of adjacent crustal blocks. The thermal variations may precede, occur consistently or be subsequent to the seismic activity. Remote observations of thermal effects are dependent on surface ground layers as well as atmospheric effects. The ultimate objective of this research is to monitor seismic activity from space. Polarization of the radiation is proposed as a technique to enhance the remote sensing observation as has been accomplished in the visible region of the spectrum.
