    Many andesitic volcanoes exhibit effusive eruption activity, with magma volumes as large as 10[sup 7]-10[sup 9] m³ erupted at rates of 1-10 m³ s[sup -1] over periods of years or decades. During such eruptions, many complex cycles in eruption rates have been observed, with periods ranging...

    The article reports that the magma chamber of mount Vesuvius in Naples, Italy has been discovered to be moving upward towards its mouth. According to Bruno Scaillet of the University of Orleans in France, it is not clear why the magma chamber has shifted, but possible reasons include changes in...

    Abstract  Minor centres in the Central Volcanic Zone (CVZ) of the Andes occur in different places and are essential indicators of magmatic processes leading to formation of composite volcano. The Andahua–Orcopampa and Huambo monogenetic fields are located in a unique tectonic...

    Mount Etna is among the few volcanoes on Earth that erupt nearly continuously, but its activity (in terms of output rate and flank eruption frequency) undergoes significant fluctuations in time. Such fluctuations do not occur randomly, but represent various stages of cycles on a scale of decades...

    The youngest dacitic Plinian eruption in west-central Nicaragua, forming the 18 km Chiltepe Tephra (CT), occurred about nineteen hundred years ago at Apoyeque stratovolcano, which dominates the Chiltepe volcanic complex 15 km north of the capital Managua, where the CT is 2 m thick. We have...

    The article offers information on volcanoes. A volcano is described as an opening in the ground or on top of a mountain. One of the world's most active volcanoes is Kilauea, which is almost always erupting. According to scientists, there are more than 500 active volcanoes in the world. The hot...
