Investigating collapse structures in oceanic islands using magnetotelluric surv...
Martínez-Moreno, F.J.; Monteiro Santos, Fernando Acácio; Madeira, José; Pous, J.; Bernardo, I.; Soares, A.; Esteves, M.; Adão, F.; Ribeiro, J.One of the most remarkable natural events on Earth are the large lateral flank collapses of oceanic volcanoes, involving volumes of rock exceeding tens of km3. These collapses are relatively frequent in recent geological times as supported by evidence found in the geomorphology of volcanic island edifices and associated debris flows deposited on the proximal ocean floor. The Island of Fogo in the Cape Verde arc...
Water prospection in volcanic islands by Time Domain Electromagnetic (TDEM) sur...
Martínez-Moreno, F.J.; Monteiro Santos, Fernando Acácio; Madeira, J.; Bernardo, I.; Soares, A.; Esteves, M.; Adão, F.Water demand in islands, focused in agriculture, domestic use and tourism, is usually supplied by groundwater. Thus the information about groundwater distribution is an important issue in islands water resources management. Time Domain Electromagnetic (TDEM) provides underground resistivity distribution at greater depths and is of easier application than other methods. In this study TDEM technique was used for ...
