Since earthquakes do not recur with sufficient frequency to acquire the necessary data in a single location , we must resort to what might be termed an " ergodic " hypothesis and study earthquakes worldwide , with the idea of recognizing patterns associated with broad sets of geological and tectonic circumstances , which presumably apply to other similar areas . Now consider two interferograms acquired over the same region as before but at different times , so that ground deformation ( due to an earthquake or volcano swelling ) has displaced many of the resolution elements for the primed interferogram in a coherent manner . The scaffold branches should have wide angles , at least sixty degrees relative to the trunk . A mature bush should have 9 to 12 canes once pruning is completed . Recent studies show that global warming may increase the frequency and intensity of fires in boreal forests and result in a significant release of carbon to the atmosphere ( Kasischke et al ., 1995b ) . In the first two years remove flowers in the spring to encourage vegetative growth . Now consider a second case , where the only surface change is a large-scale coherent change common to several adjacent pixels .
