The Earth's most historically active cinder cone is Cerro Negro in Nicaragua. [3] It is part of a group of four young cinder cones NW of Las Pilas volcano. Since its initial eruption in 1850, it has erupted more than 20 times, most recently in 1995 and 1999. [3]

Cinder cones, also known as pyroclastic cones, are the smallest and the simplest type of volcano. They are the world's most common volcanic landform. As the name "cinder cone" suggests, they are cone-shaped hills made up of ejected igneous rocks known as "cinders".

2024年9月3日 · A cinder cone volcano, also known as a pyroclastic cone or scoria cone, is a volcano with a simple, steep-sided conical shape consisting of cinders and other volcanic debris from an explosive eruption.

2024年4月2日 · Cinder cones are the “most endangered” volcanoes on Earth because of the many uses humans have for cinders. They are easily mined for cinders to use in road construction, to sand icy roads, and for “lava rocks” for gas grills.

2023年12月24日 · Cinder cone volcanoes or scoria cones are small, steep-sided, conical-shaped, nearly circular, or oval hills. These hills are made of highly vesiculated, mafic to intermediate loose pyroclastic fragments or ejecta.

cinder cone, deposit around a volcanic vent, formed by pyroclastic rock fragments (formed by volcanic or igneous action), or cinders, which accumulate and gradually build a conical hill with a bowl-shaped crater at the top.

When cinder cones spew out this gaseous lava, it spits it up in the air. But it splatters around the vent and welds together. Eventually, it cools down and becomes part of its steep cone-like feature. Lava rarely flows from the top of a cinder. Instead, …

Cinder cones are the type of volcano that is formed by pyroclastic fragments like volcanic ashes, solidified lava pieces, volcanic clinkers, pumice and hot gases. These volcanoes are formed around the volcanic vent and are known to be the simplest form of a volcano.

2022年12月22日 · Cinder cones are large mounds that develop around volcanic vents, made up of tiny pieces of falling lava that get distributed during an eruption. In an eruption, hot, pressurized lava may be spewed skyward.

At the high-fountaining end of the spectrum are cinder cones. Cinder cones can be quite large in Hawai'i; those on the summit of Mauna Kea (formed during gas-rich alkalic-stage eruptions) are a few hundred meters high, whereas those on Mauna Loa and Kilauea usually range between 20 and 100 m high.
