地質学的概要
The symmetrical, forested Volcán de Agua stratovolcano forms an impressive backdrop to the city of Antigua, Guatemala, opposite from the Fuego and Acatenango volcanoes. The isolated basaltic andesite to andesite edifice makes it a prominent landmark visible from all directions. A circular 280-m-wide crater is breached on the NNE, six small pit craters are located on the NW flank, and two small cones lie on the S flank. No dated Holocene tephra deposits or recorded eruptions are known from Agua, but its name (the water volcano) originates from a devastating mudflow on 11 September 1541. The mudflow destroyed Ciudad Vieja, the first Guatemalan capital city established by the Spanish Conquistadors, prompting the establishment of a new capital at nearby Antigua.
Wikipedia の要約
英語版の要約Volcán de Agua is an extinct stratovolcano located in the departments of Sacatepéquez and Escuintla in Guatemala. At 3,760 m (12,340 ft), Agua Volcano towers more than 3,500 m (11,500 ft) above the Pacific coastal plain to the south and 2,000 m (6,600 ft) above the Guatemalan Highlands to the north. It dominates the local landscape except when hidden by cloud cover. The volcano is within 5 to 10 km of the city of Antigua Guatemala and several other large towns situated on its northern apron. These towns have a combined population of nearly 100,000. It is within about 20 km (12 mi) of Escuintla to the south. Coffee is grown on the volcano's lower slopes.
