Answer:
1. Most earthquakes are along the edges of the tectonic plates. This is where most volcanoes also occur. So most earthquakes are caused by the interaction of the plates not the movement of Magma. Thus earthquakes are closely associated with volcanic belts.
2. Lava is the hot molten rock that erupts after a volcanic eruption. When lava comes to the surface of the earth, it cools and solidifies. This lava is rich in minerals. Further, the lava and the volcanic ash often contain minerals that are beneficial to plants, and if it is very fine ash it is able to break down quickly and get mixed into the soil. Black soil is also formed as a result of volcanic activity. This soil is useful for growing cotton. Thus, lava activity is profitable for humans.
3. The Ring of Fire also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. Its length is approximately 40,000 kilometers (24,900 miles). It traces boundaries between several tectonic plates—including the Pacific, Juan de Fuca, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates.
Seventy-five percent of Earth’s volcanoes—more than 450 volcanoes—are located along the Ring of Fire. Ninety percent of Earth’s earthquakes occur along its path, including the planet’s most violent and dramatic seismic events.
4. Over geologic time, volcanic eruptions and related processes have directly and indirectly benefited mankind: Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, cultivation of which has produced abundant food and fostered civilizations.
5. Vesuvius is still regarded as an active volcano, although its current activity produces little more than sulfur-rich steam from vents at the bottom and walls of the crater. Vesuvius is a stratovolcano at the convergent boundary where the African Plate is being subducted beneath the Eurasian Plate.
Last eruption: 17–23 March 1944
