This geological wonder of about 40,000 interlocking basalt columns in County Antrim is the result of an ancient volcanic fissure eruption
and Eamonn describes how it intrigued and inspired him.
Made up of 40,000 interlocking basalt columns, this SPECTACULAR The Giant's Causeway geological wonder is the result of an ancient volcanic fissure eruption
Lava gushes from a fissure eruption
of the Kilauea Volcano in the Leilani Estates near Pahoa, Hawaii.
The Kilauea volcano has been active since a fissure eruption
on in January 1983.
A massive white cloud some 4.5 kilometers tall was rising above the fissure eruption
The estimated 1-km fissure eruption
in the Holuhraun area prompted the Icelandic Met Office to raise the warning code for aviation to red, the highest level.
The Plosky Tolbachik erupted 10 times since records began in 1740, with the most notable eruption in 1975, commonly known as The Great Tolbachik Fissure Eruption
. Soviet scientists successfully predicted the eruption because it was preceded by a series of earthquakes.
The Hawaiian Volcano Observatory said the fissure eruption
was spotted shortly after the floor at the Pu'u O'o collapsed on Saturday afternoon.
FIGURE 7 The upper part of the figure shows the chain of calderas called Tvashtar Catena on Io, showing a fissure eruption
Locality: The fumarole "Treschina" in the northern part of the central fumarole field of cone II of the Northern Break of the Large Tolbachik Fissure Eruption
, Kamchatka Peninsula, Russia.
Hummocky ridges are formed when the fissure eruption
becomes confined to several vents along its length, similar to spatter cones or spatter ramparts that form along fissures in Iceland and Hawaii.
Stothers and Courtillot make note ofthe 1783 Laki fissure eruption
in Iceland, which sent a haze containing more than 10 million tons of sulfuric acid over Europe and into Asia and North Africa.
