| Research Abstract |
Palsas are permafrost mounds which indicate the presence of permafrost geomorphologically. In Japan, they are distributed only in the Daisetsu Mountains. Meteorological, ground temperature and electric resistivity measurements and survey of the distribution of palsas were conducted. The rapid degradation of them was detected in 2010. Permafrost temperatures of palsas were indicated to be near 0℃. Most of them do not seem to be active.
