Abstract
Multi-temporal MODIS thermal imagery isolates geothermal from seasonal land surface temperature (LST) variability in Afar Depression and identifies localized LST thermal anomalies during the September 2005 seismo-volcanic crisis. The interpretation of the monthly night annual imagery sequences and time series analysis proved that in the northern and the central parts, LST is maximized throughout the year. The two regions lie along the NW-SE trending Red Sea Propagator, which is the on-land southern termination of the Red Sea Rift. Linear regression analysis proved that LST variation is terrain elevation dependent. Terrain segmentation outlined 5 terrain classes. The localized geothermal activity during the September 2005 seismic-volcanic crisis activity in both Erta Ale and Dabbahu vicinity was revealed by combined terrain-LST modelling. The LST statistics of the segmented terrain classes revealed that in September 2005, a regional minor increase in LST also affected the four classes with positive elevation.
