We study the spectral and temporal behavior of X-ray flares from the activeM-dwarf EV Lac in 200 ks of exposure with the Chandra/HETGS. We derive flareparameters by fitting an empirical function which characterizes the amplitude,shape, and scale. The flares range from very short (<1 ks) to long (10 ks)duration events with a range of shapes and amplitudes for all durations. Weextract spectra for composite flares to study their mean evolution and tocompare flares of different lengths. Evolution of spectral features in thedensity-temperature plane shows probable sustained heating. The short flaresare significantly hotter than the longer flares. We determined an upper limitto the Fe K fluorescent flux, the best fit value being close to what isexpected for compact loops.
