Volcanic cones are among the simplest volcano formations. They are built by fragments (called ejecta) thrown up (ejected) from a volcanic vent, piling up around the vent in the shape of a cone ...

Lēʻahi (Diamond Head) is a volcanic tuff cone, and it’s a famous landmark in Waikīkī. The volcanic hike offers a historic hiking trail leading to stunning panoramic views of the Pacific ...

Scientists have found previously undocumented ash deposits buried beneath the Lava Creek Tuff in Wyoming — and at least one of them could be from an unknown volcanic eruption, they say.

It’s a volcanic tuff cone that has an old railway track to the summit that has been converted into a running/hiking/climbing/crawling trail. The reason most everyone does it?

While working under Erika Rader, an assistant professor in the Department of Earth and Spatial Sciences at University of Idaho, a postdoctoral researcher identified a volcanic vent on Mars as a ...

The Diamond Head cone is very symmetrical like the rim of a paper cup. Because of its very circular shape, scientists think the cone cooled off quickly after a single, highly-explosive volcanic ...

30 January 2013, 11:30am - Small tuff cone forming; Volcanic Alert remains at level 1, Aviation Colour Code remains Orange. The ‘hot lake’ has now dried out and a small tuff cone has started ...

New Tongan island made of 'tuff' stuff, likely to persist years, NASA shows Date: December 11, 2017 Source: NASA/Goddard Space Flight Center Summary: In late December 2014, a submarine volcano in ...

Blazing yellow lichen clings to welded tuff, igneous rock containing debris fragments from an explosive volcanic eruption. The footpath makes an ascending traverse to claim the top of the divide.

The researchers are convinced that these are true volcanic cones, similar to common volcanoes on Earth known as scoria cones and tuff cones.
