By Bernhard Edmaier. RINCON DE LA VIEJA, COSTA RICA Rincon de la Vieja is one of the most closely watched volcanoes in Costa Rica, its active crater in particular. Filled with a hot acid lake, it has a diameter of around 500 metres. Hot corrosive mudslides rush down the mountain during eruptions, endangering villages and plantations at its foot.
