Ground thermal conditions at Chachani Volcano, southern Peru / Nuria Andrés.
Title: | Ground thermal conditions at Chachani Volcano, southern Peru / Nuria Andrés. |
Author(s): | Andrés, Nuria. |
Date: | 2011. |
In: | Geografiska Annaler. Series A. Physical Geography. (2011.), Vol. 93(3) (2011) |
Abstract: | Analyzes temperature variations in shallow ground and distribution of annual average air temperatures to determine elevational boundaries for periglacial and permafrost environments. Short snow cover duration and difficult access make BTS method and borehole drilling inapplicable. Uses instead data from three stations on southern slope to model ground temperature distribution with depth and altitude. Air and ground temperatures oscillate around 0°C almost daily, but temperature stabilizes a few cm below surface. Finds lower limit of thermal conditions for isolated permafrost patches at 5,050 m a.s.l., conditions for discontinuous permafrost from 5,250 to 5,420 m, and continuous permafrost above this level. Shows that rock glaciers on southern slopes are within active permafrost zone. |
