Visit them and you find bubbling mud ponds, hot springs and scores of steaming vents.This steam has been used by locals for washing and bathing, but underlying this is a much bigger opportunity.The surface activity suggests extremely hot fluids deep below, perhaps up to 300°C–400°C.Drill down and it should be possible access this high temperature steam, which could drive large turbines and produce huge amounts of power.This matters greatly in a country where 77% of the population has no access to electricity, one of the lowest levels in Africa.Geothermal power has recently become a serious proposition thanks to geophysical surveys suggesting that some volcanoes could yield a gigawatt of power.

In this paper, Sun-photometer multichannel measurements of aerosol optical depths AODs in the visible and near-infrared spectral ranges, and Ångström parameters of the plume issued from the Pacaya volcano, Guatemala, are presented for the first time. These observations, made during a short-term.
