Calderas often vary in size ranging from 1 to 100 kilometres in diameter. Today, there is no sign of an imminent reawakening, although there are abundant signs of the presence of a still active magma chamber in the forms of solfataras, warm springs, and gas emissions. About 150km in diameter,the caldera is comparable to the biggest impact craters on Earth and bigger than any other known calderas on this planet. A paper on the discovery has been published in the journal Marine Geology. Barretto remarks, There are these scientific data available, which have not been analyzed in detail.
