A new methodology<\/a>, based on a subtle but significant increase in heat emissions over large areas of a volcano in the years before its eruption<\/strong>, can predict these events with enough margin in advance. This makes it possible to see that a volcano has reawakened, often long before the other signs appear.<\/p>\n

<\/p>\n

The new method was developed using satellite data by scientists at NASA and the University of Alaska in Fairbanks.<\/p>\n

For several types of volcanoes that have erupted in the past two decades, the study team analyzed 16 and a half years of radiant heat data from Moderate Resolution Imaging Spectroradiometers (MODIS). aboard NASA's Terra and Aqua satellites<\/strong>.<\/p>\n

We have the first evidence that there are not only volcanoes on Venus but that they are also active<\/a>\n <\/div><\/div><\/div>\n<\/div>\n

Despite the differences between the volcanoes, the results were consistent: in the years before an eruption, the radiant surface temperature across much of the volcano rose about 1 degree Celsius above its normal state. It decreased after each eruption.<\/p>\n

<\/p>\n

In particular, scientists believe that the increase in heat may result from the interaction between magma reservoirs and hydrothermal systems. As explained by the co-author from the study<\/a>, Paul Lundgren<\/strong> from JPL (Jet Propulsion Laboratory):<\/p>\n

Volcanoes are like a box of mixed chocolates: they may look similar, but inside there is a lot of variety between them and sometimes even within the same one. On top of that, only a few volcanoes are well monitored, and some of the most potentially dangerous volcanoes are the ones that erupt the least frequently, meaning historical records cannot be strictly relied upon.<\/p>\n<\/blockquote>\n
