Volcano

Record date occurs prior to the earthquakes volcanoes, where previously an explosion Hawaii are two types of earthquakes near the type of surface does not exceed the post-quake's epicenter about 8 km from the surface, and the type of event on the abyssal depths of 60 kilometers beneath the surface of the earth. In some cases, tremors preceded by several years of volcanic eruptions, for example those earthquakes that lasted 16 years before the eruption of Mount Vesuvius (79 BC). As well as the earthquakes, which lasted several years before an explosion hits Kilau volcano in Hawaii. In this area, (the Centre for Monitoring volcanoes) in Hawaii in several field studies on this phenomenon in 1942 where he scored an earthquake violent Monallowa Maunaloa on the dimensions of the ancient Earth's surface ranging between 40-50 km. On 22 February of that year earthquakes took place close to the surface on the sides of the mountain in the fracture zones.
This was a warning to the tremors of a volcanic eruption that took place on the sides of the mountain at an altitude of 2500-3000 m, on April 26, 1942. But you can predict the precise time of occurrence of volcanic activity?
To answer this question, we must know that scientists are still volcanoes Itraithwn to make any definite predictions and accurate information about time and place of occurrence of such explosions, however, there are some events and evidence which we can infer from the possibility of volcanic eruptions, namely:
