Unfrozen state by the supercooling of chuño for traditional agriculture in altiplano andes
Autor: Kenji Yoshikawa, Fredy Apaza
Publikováno v: Environmental and Sustainability Indicators, Vol 8, Iss , Pp 100063- (2020)
The freezing point and supercooling process are discussed for their impact on the traditional Andean freeze-dried potatoes called chuño. The freezing point depends on potato species, but typically it is slightly below zero to −3 ​°C; supercooli

Volcanic plumes are common and far-reaching manifestations of volcanic activity during and between eruptions. Observations of the rate of emission and composition of volcanic plumes are essential to recognize and, in some cases, predict the state of

Tropical high‐mountain permafrost has a unique thermal regime due to its exposure to strong solar radiation and to rough surface snow morphology, which reduce ground heat transfer from the surface. Latent heat transfer and higher albedo that occur

The July 2019 explosive activity of Ubinas Volcano, Peru
Autor: Fredy Apaza, Christoph Kern, Mayra Ortega, Rafael Miranda
Ubinas is a stratovolcano located in the Central Volcanic Zone of the Andes. It is one of the most active volcanoes in Peru, with more than 26 eruptive episodes recorded in the last 500 years (VEI 1-3). Its latest eruption began in early 2019, whit t
