List of volcanoes in Iceland

List of volcanoes in Iceland is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of volcanoes in Iceland rather than just read about it. In short: 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. This list of volcanoes in Iceland only includes major active and dormant volcanic mountains, of which at least 18 vents have erupted since human settlement of Iceland began around 900 AD.

Key takeaways

List of volcanoes in Iceland belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect List of volcanoes in Iceland to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of List of volcanoes in Iceland from memory before moving on to harder problems.

Reference excerpt

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. This list of volcanoes in Iceland only includes major active and dormant volcanic mountains, of which at least 18 vents have erupted since human settlement of Iceland began around 900 AD. Subsequent to the main list a list is presented that classifies the volcanoes into zones, systems and types. This is in the context that there are several classification systems and many of the volcanoes may have separate shallow magma chambers and a deeper common magma source. Where a major vent is part of a larger volcano this is indicated in the list comment. Since some of these vent eruptions have been very large, disruptive or been regarded in popular culture as a separate volcano they have been included in the list but where this is not the case it is not appropriate to duplicate or create entries. So for minor vent eruptions since human occupation see the more comprehensive list of volcanic eruptions in Iceland.

Volcanic zones and systems

Iceland has four major volcanic zones related a divergent tectonic plate boundary, and a hot spot:

the Reykjanes volcanic zone (RVZ), subdivided into the Reykjanes Ridge (RR) (the Mid-Atlantic Ridge South of Iceland) and the Reykjanes Volcanic Belt (RVB) (on the main island); the West Volcanic Zone (WVZ); the East Volcanic Zone (EVZ) (extended to the Westman Islands, south of the main island as part off the off rift, South Iceland volcanic zone (SIVZ)); the North volcanic zone (NVZ). The Mid-Iceland Belt (MIB) connects them across central Iceland. In Iceland's EVZ, the central volcanoes, Vonarskarð and Hágöngur belong to the same volcanic system; this also applies to Bárðarbunga and Hamarinn, and possibly to Grímsvötn and Þórðarhyrna. The classification of volcanic systems depends on volcanology studies and has evolved with time. For example, while Grímsvötn and Þórðarhyrna have similar eruptive compositions, as of 2020 Þórðarhyrna had not been studied in enough detail to have assurance that these are not two separate central volcanoes of two separate volcanic systems. The southern tip of the EVZ propagating rift is an off rift region called the South Iceland volcanic zone (SIVZ), that often has more evolved magma and thus explosive eruptions. North of Iceland, the Mid-Atlantic Ridge is called Kolbeinsey Ridge (KR) and is connected to the NVZ via the Tjörnes fracture zone (TFZ). Also the South Iceland seismic zone (SISZ) is another fracture zone, which connects the EVZ and WVZ. Both fracture zones include their own volcanic systems, smaller than those in the MIB. There are also two intraplate volcanic belts: Öræfajökull or Öræfi, (ÖVB) on the Eurasian plate, and Snæfellsnes (SVB) on the North American plate. It is proposed that the east–west line going from the Grímsvötn volcano in the Mid-Iceland Belt (MIB) to the Snæfellsnes volcanic belt (SVB) shows the movement of the North American plate over the Iceland hotspot.

Worked examples

Example 1 — a first encounter with List of volcanoes in Iceland

Start with the simplest possible case. Write down what List of volcanoes in Iceland claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of volcanoes in Iceland before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of volcanoes in Iceland ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of volcanoes in Iceland

In research: List of volcanoes in Iceland appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of volcanoes in Iceland in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of volcanoes in Iceland is common in secondary-school and first-year university syllabi. It links to neighbouring topics Iceland geology-related lists, Lists of landforms of Iceland, Lists of volcanoes, so understanding it makes those chapters shorter.
In everyday life: Look for List of volcanoes in Iceland outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
