Caldera Blanca is a type of volcano called a phreatomagmatic tuff cone. Phreatomagmatic refers to the fact that the lava which was erupted by the volcano came into contact with water (probably seawater as this volcano is situated close to the Atlantic Ocean). When lava and water mix, the eruption becomes violently explosive. This explains why the centre of the cone has been blown away by the force of the expanding gases (principally water vapour) The cone is composed of tuff, a general term for a rock composed of volcanic ash. You can see the layers from successive eruptions in the wall of the cone.

The Ardnamurchan Caldera (part), first outing for this image (6 shot pano) from a couple of years ago, with the small isles, Skye and the Black Cuillins on the horizon.
Ardnamurchan, located in the Scottish Highlands, is the site of an ancient, eroded volcano. What remains is a complex geological structure, including a lopolith (a saucer-shaped intrusion of magma) and ring dikes, exposed at the surface due to erosion by glaciers. The volcano formed approximately 60 million years ago and was active during the early Tertiary period.
Looking down into one of the calderas on Gran Canaria in the Canary Islands. A caldera is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption.
We was literally at the eye of a volcano! I don’t get to see these often, but it was a site to see. More to come.
Caldera Blanca is a volcano on the Spanish Canary island of Lanzarote. The wide crater (or caldera) is typical of volcanic cones on Lanzarote: the magma often interacted with the nearby sea or ground water to produce highly explosive eruptions which formed these impressive wide craters (the Atlantic Ocean is close here, as you can see). Caldera Blanca - the White Caldera - is so named because lichen and caliche (a sort of soil/rock composed largely of white-ish calcium carbonate) give it a light appearance that contrasts with the predominantly black rocks elsewhere on the island.
VALLES CALDERA NATIONAL PRESERVE NEW MEXICO
Located in the young volcanic Jemez Mountains, the Valles Caldera is a one-million-year-old supervolcano. The present day open grassy floor of the structure is home to a large variety of wildlife, including Elk. Only a small portion of the 13.8-mile-wide caldera is visible in this image.
The volcano at Soufriere, St.Lucia, known as Sulphur Springs, holds the distinction of being the world's only drive-in volcano.
The last St. Lucia volcano eruption occurred back in the late 1700's and was a steam eruption rather than a magma one. While it lies dormant, however, the volcano is still very hot. This heat lends itself to many boiling pools of water and mud. You can actually hear the pots boiling long before you can see them, and when you do reach them, you will find that they are multicolored due to the many minerals they contain.
Walking in the crater is no longer allowed, due to a guide who fell into the boiling water while jumping up and down on the crater. The guide was rescued, but his mishap has led to restrictions on where people are allowed to walk.
The volcano in St. Lucia has a strong smell of sulphur, but this is actually a good thing even when it can be smelled from miles away, as the dissipation of the odor would mean that an eruption was coming. We were told that the plant life would die and the animals and birds would disappear which would also be a sign of an impending eruption.
It's fascinating to see the liquid bubbling and to smell the sulphur in this amazing natural phenomenon. You can see the liquid bubbling in the bottom left hand corner.
