Hekla 3 eruption, the Glossary

The Hekla 3 eruption (H-3) is considered the most severe eruption of Hekla during the Holocene.^[1]

Before Present

Before Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s.

Bog-wood

Bog-wood (also spelled bogwood or bog wood), also known as abonos and, especially amongst pipe smokers, as morta, is a material from trees that have been buried in peat bogs and preserved from decay by the acidic and anaerobic bog conditions, sometimes for hundreds or even thousands of years.

Global cooling

Global cooling was a conjecture, especially during the 1970s, of imminent cooling of the Earth culminating in a period of extensive glaciation, due to the cooling effects of aerosols or orbital forcing.

Iceland hotspot

The Iceland hotspot is a hotspot which is partly responsible for the high volcanic activity which has formed the Iceland Plateau and the island of Iceland.

Late Bronze Age collapse

The Late Bronze Age collapse was a time of widespread societal collapse during the 12th century BC associated with environmental change, mass migration, and the destruction of cities. Hekla 3 eruption and Late Bronze Age collapse are volcanic winters.

List of volcanoes in Iceland

There are too many presumed extinct or now inactive volcanic features to list all of these below, so most monogenetic volcanoes can not be mentioned individually.

Plinian eruption

Plinian eruptions or Vesuvian eruptions are volcanic eruptions marked by their similarity to the eruption of Mount Vesuvius in 79 AD, which destroyed the ancient Roman cities of Herculaneum and Pompeii. Hekla 3 eruption and Plinian eruption are Plinian eruptions.

Stalagmite

A stalagmite is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings.

Sutherland

Sutherland (Cataibh) is a historic county, registration county and lieutenancy area in the Highlands of Scotland.

Volcanic explosivity index

The volcanic explosivity index (VEI) is a relative measure of the explosiveness of volcanic eruptions.

See Hekla 3 eruption and Volcanic explosivity index

Volcanic rock

Volcanic rocks (often shortened to volcanics in scientific contexts) are rocks formed from lava erupted from a volcano.

Volcanic winter

A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption. Hekla 3 eruption and volcanic winter are volcanic winters.

Volcanism of Iceland

Iceland experiences frequent volcanic activity, due to its location both on the Mid-Atlantic Ridge, a divergent tectonic plate boundary, and being over a hotspot. Nearly thirty volcanoes are known to have erupted in the Holocene epoch; these include Eldgjá, source of the largest lava eruption in human history.
