Some of the volcanonic eruptions in 2021 are:
Kilauea, United States; La Palma, Spain; Ulawun, Papua New Guinea; Krakatau, Indonesia, Merapi, Indonesia, Semeru, Indonesia; Etna, Italy; Bezymianny, Russia; Reventador, Ecuador; Ibu, Indonesia; Stromboli, Italy.
Volcanic eruptions have directly and indirectly benefited environment:
- Volcanic materials break down and weather to form the most fertile soils on Earth.
- The internal heat associated with young volcanic systems has produce geothermal energy.
- Metallic minerals mined in the world–such as copper, gold, silver, lead, and zinc–are associated with magmas found deep within the roots of extinct volcanoes.
