* Erupt effusively: This means they release lava slowly and steadily, often creating large lava flows. These eruptions are usually less explosive and generate less ash than explosive eruptions.
* Have low-viscosity magma: The magma, which is molten rock beneath the surface, is thin and runny. This allows it to flow easily and erupt relatively peacefully.
* Often form shield volcanoes: Shield volcanoes are broad, gently sloping volcanoes that are built up by layers of lava flows. They are typically associated with quiet eruptions.
Examples of quiet volcanoes:
* Kilauea (Hawaii): Famous for its long-lasting lava flows.
* Mauna Loa (Hawaii): The largest active volcano on Earth, known for its effusive eruptions.
* Mount Etna (Italy): Often erupts quietly with lava flows, although it can also have more explosive phases.
Important Note: Even quiet volcanoes can be dangerous. Lava flows can be destructive, and even effusive eruptions can release gases that can be harmful.
It's important to remember that any volcano can erupt explosively, regardless of its previous behavior.
