activity was recorded around the amphitheatre; there were no earthquakes within it and appeared to be associated mainly with the faults and lineaments in the region. The researchers recommended more extensive seismometer coverage of the area and regular sampling of fumaroles, as well as reconnaissance with georadar and of the electrical potential of the volcano. Climate and vegetation Between in elevation average temperatures are about with cold nights, while at Omate, mean temperatures reach with little seasonal variation. Precipitation averages , falling mainly during a summer wet season between December and March. This results in an arid climate, where little erosion occurs and volcanic products are well preserved. Vegetation in the area of Huaynaputina is scarce; only during the wet season do plants grow on the pumice deposits from the 1600 eruption. Cacti can be found on rocky outcrops and valley bottoms.
