Volcano types: Cinder cone, composite, shield and lava domes explained - TomoNews
EARTH — A volcano is an opening in the earth's surface where molten rock can escape. The earth's crust is made up of tectonic plates that shift and move. Volcanoes are often located at the fault lines between these plates.
Volcanoes can be active, dormant or extinct, according to Universe Today.
There are four major types of volcanoes: cinder cone, composite, shield and lava domes.
Cinder cone volcanoes occur when lava is ejected from a volcanic vent. Lava is shot into the air, and pieces accumulate around the vent. Over time, this creates a circular or oval-shaped cone, with a crater at the top.
Composite volcanoes contain a conduit system that channels magma to the surface. These volcanoes can have clusters of vents along the sides of the mountain where lava flows out.

EARTH — A volcano is an opening in the earth's surface where molten rock can escape. The earth's crust is made up of tectonic plates that shift and move. Volcanoes are often located at the fault lines between these plates.
Volcanoes can be active, dormant or extinct, according to Universe Today.
There are four major types of volcanoes: cinder cone, composite, shield and lava domes.
Cinder cone volcanoes occur when lava is ejected from a volcanic vent. Lava is shot into the air, and pieces accumulate around the vent. Over time, this creates a circular or oval-shaped cone, with a crater at the top.
Composite volcanoes contain a conduit system that channels magma to the surface. These volcanoes can have clusters of vents along the sides of the mountain where lava flows out.
Shield volcanoes are large, broad volcanoes where lava pours out in thin layers, allowing it to travel farther down the shallow slopes of the volcano. Shield volcanoes build up slowly with hundreds of eruptions creating several layers.
Lava domes are created when small masses of thick lava that can't flow far from the source, so domes pile up around the vent. The dome grows by expansion of lava from within, and the mountain forms from material spilling off the sides of the dome.

https://en.vedur.is/earthquakes-and-volcanism/earthquakes#view=map
Fagradalsfjall (Icelandic pronunciation: [ˈfaɣraˌtalsˌfjatl̥]) is a shield volcano on the Reykjanes Peninsula, around 40 kilometres (25 mi) from Reykjavík, Iceland. Its highest summit is Langhóll (385 m (1,263 ft)). A volcanic eruption began on 19 March 2021 in Geldingadalir to the south of Fagradalsfjall, which is still emitting fresh lava as of 1 June 2021. Due to its relative ease of access from Reykjavík, the volcano has become an attraction for both the locals and foreign tourists alike.
The mountain Fagradalsfjall is a volcano of the Krýsuvík-Trölladyngja volcanic system on the Reykjanes Peninsula in southwest Iceland. It is situated within a zone of active rifting at the divergent boundary between the Eurasian and North American plates. The Krýsuvík volcanic system has been moderately active in the Holocene, with the most recent eruptive episode before the 21st century having occurred in the 12th-century′ CE.
Other scientists propose that Fagradalsfjall could represent a separate volcanic system.
The unrest and eruption in Fagradalsfjall are part of a larger unrest period on Reykjanes Peninsula including unrest within several volcanic systems and among others also the unrest at Þorbjörn volcano next to Svartsengi and the Blue Lagoon during the spring of 2020.
Beginning December 2019 and into March 2021, a swarm of earthquakes, two of which reached magnitude Mw5.6, rocked the Reykjanes peninsula, sparking concerns that an eruption was imminent, because the earthquakes were thought to have been triggered by dyke intrusions and magma movements under the peninsula. Minor damage to homes from a 4 February 2021 magnitude 5.7 earthquake was reported. In the three weeks prior to the eruption, more than 40,000 tremors were recorded by seismographs.
On 19 March 2021, an effusive eruption started at approximately 8:45 PM local time in Geldingadalir ([ˈcɛltiŋkaˌtaːlɪr̥] "gelding valleys", the singular "Geldingadalur" [-lʏr̥] is also often used) to the south of Fagradalsfjall, the first known eruption on the peninsula in about 800 years. Fagradalsfjall has been dormant for 6,000 years. The eruptive activity was first announced by the Icelandic Meteorological Office at 9:40 Pm. Reports state a 600–700-metre-long (2,000–2,300 ft) fissure vent began ejecting lava, which covered an area of less than 1 square kilometre (0.39 sq mi). Currently, the lava flows pose no threat to residents, as the area is mostly uninhabited, although there is potential for sulfur dioxide pollution.
The eruption has been called Geldingadalsgos ([-ˌtalsˌkɔːs] "Geldingadalur eruption"). As of 26 March, the main eruptive vent was at 63.8889 N, 22.2704 W, on the site of a previous eruptive mound. The eruption may be a shield volcano Eruption, which may last for several years. It is visible from the suburbs of the capital city of Reykjavík and has attracted a large number of visitors. However, high levels of volcanic gases such as carbon dioxide and carbon monoxide make parts of the area inaccessible.
The eruption pattern changed on 2 May from a continuous eruption and lava flow to a pulsating one, where periods of eruptions alternate with periods of inactivity.
Two defensive barriers were created starting 14 May in an attempt to stop lava flowing into the Nátthagi [ˈnauhtˌhaijɪ] valley where telecommunication cables are buried, and further on to the southern coastal road. However, the lava soon flowed over the top of eastern barrier 22 May, and cascaded down to the Nátthagi.

“What nerve!” you might say. What… gall! And you’d be right. The wasps are called gall-inducers.
---+ What do oak galls look like?
If you’ve ever spent a Summer or Fall around oak trees – such as the stalwart Valley Oak – Quercus lobata, or the stately Blue Oak, Quercus douglasii – you may be familiar with the large, vaguely fruity-looking objects clinging to the branches and leaves. Commonly called oak apples, these growths are the last thing you’d want to put in your mouth. They are intensely bitter, loaded with tannin compounds – the same compounds that in modest amounts give red wine its pleasant dryness, and tea its refreshing earthy tang.
That said, the oak apple’s powerful astringency has been prized for millennia. Tanning leather, making ink or dye, and cleaning wounds have been but a few of the gall’s historical uses.
But on closer inspection of these oaks – and many other plants and trees such as willows, alders, manzanitas, or pines – you can find a rogue’s gallery of smaller galls. Carefully peeking under leaves, along the stems and branches, or around the flower buds and acorns will likely lead you to unexpected finds. Smooth ones. Spiky ones. Long skinny ones, flat ones, lumpy, boxy ones. From the size of a golf ball down to that of a poppy seed. These structures wear shades of yellow, green, brown, purple, pink and red – and sometimes all of the above. A single tree may be host to dozens of types of gall, each one caused by a specific organism. And their shapes range from the sublime to the downright creepy. One tree may be encrusted with them, like a Christmas tree laden with ornaments and tinsel; and the next tree over may be almost completely free of galls. Why? It’s a mystery.
---+ How do oak galls form?
Galls are generally formed when an insect, or its larvae, introduce chemicals into a specific location, to push the plant’s growth hormones into overdrive. This can result in a great profusion of normal cells, increased size of existing cells, or the alteration of entire plant structures into new, alien forms.
Lots of creatures cause them; midges, mites, aphids, flies, even bacteria and viruses. But the undisputed champs are a big family of little wasps called Cynipids– rarely exceeding the size of a mosquito, a quarter of an inch in length.
“These tiny wasps cannot sting,” says Dr. Kathy Schick, Assistant Specialist/Curatorial Assistant at the Essig Museum of Entomology at UC Berkeley. “Gall-inducers are fascinating in that they are very specialized to their organ of the host plant.”
---+ What are oak galls?
These wasp houses are not homes exactly, but more akin to nurseries. The galls serve as an ideal environment for wasp larvae, whether it is a single offspring, or dozens. The tree is tricked into generating outsize amounts of soft, pillowy tissue inside each gall, on which the larvae gladly gorge themselves as they grow.

Plenty of animals build their homes in oak trees. But some very teeny, tricky wasps make the tree do all the work. And each miniature mansion the trees build for the wasps' larvae is weirder and more flamboyant than the next.

“What nerve!” you might say. What… gall! And you’d be right. The wasps are called gall-inducers.
---+ What do oak galls look like?
If you’ve ever spent a Summer or Fall around oak trees – such as the stalwart Valley Oak – Quercus lobata, or the stately Blue Oak, Quercus douglasii – you may be familiar with the large, vaguely fruity-looking objects clinging to the branches and leaves. Commonly called oak apples, these growths are the last thing you’d want to put in your mouth. They are intensely bitter, loaded with tannin compounds – the same compounds that in modest amounts give red wine its pleasant dryness, and tea its refreshing earthy tang.
That said, the oak apple’s powerful astringency has been prized for millennia. Tanning leather, making ink or dye, and cleaning wounds have been but a few of the gall’s historical uses.
But on closer inspection of these oaks – and many other plants and trees such as willows, alders, manzanitas, or pines – you can find a rogue’s gallery of smaller galls. Carefully peeking under leaves, along the stems and branches, or around the flower buds and acorns will likely lead you to unexpected finds. Smooth ones. Spiky ones. Long skinny ones, flat ones, lumpy, boxy ones. From the size of a golf ball down to that of a poppy seed. These structures wear shades of yellow, green, brown, purple, pink and red – and sometimes all of the above. A single tree may be host to dozens of types of gall, each one caused by a specific organism. And their shapes range from the sublime to the downright creepy. One tree may be encrusted with them, like a Christmas tree laden with ornaments and tinsel; and the next tree over may be almost completely free of galls. Why? It’s a mystery.
---+ How do oak galls form?
Galls are generally formed when an insect, or its larvae, introduce chemicals into a specific location, to push the plant’s growth hormones into overdrive. This can result in a great profusion of normal cells, increased size of existing cells, or the alteration of entire plant structures into new, alien forms.
Lots of creatures cause them; midges, mites, aphids, flies, even bacteria and viruses. But the undisputed champs are a big family of little wasps called Cynipids– rarely exceeding the size of a mosquito, a quarter of an inch in length.
“These tiny wasps cannot sting,” says Dr. Kathy Schick, Assistant Specialist/Curatorial Assistant at the Essig Museum of Entomology at UC Berkeley. “Gall-inducers are fascinating in that they are very specialized to their organ of the host plant.”
---+ What are oak galls?
These wasp houses are not homes exactly, but more akin to nurseries. The galls serve as an ideal environment for wasp larvae, whether it is a single offspring, or dozens. The tree is tricked into generating outsize amounts of soft, pillowy tissue inside each gall, on which the larvae gladly gorge themselves as they grow.

Watch the BBC first on iPlayer 👉 https://bbc.in/iPlayer-Home Once again Nature's Weirdest Events has trawled the internet, raided their contact book and scoured the scientific world to unearth a treasure trove of bizarre and baffling stories. Using UGC clips of the events themselves, Chris Packham deconstructs the weirdness using eyewitness accounts, scientists and BBC archive footage.
In this series there is everything from scores of pigs swimming in the Caribbean to the tiny tick that is turning America vegetarian. There is a giant worm decimating fish tanks, a strange blob appearing when comets are seen, the real-life sea serpent washed up on the Californian coast and a Japanese island swarming with rabbits.
In the UK a virgin snake gives birth, in the US a sea serpent washes up and in Morocco 12 goats stand stock still in a tree. It's a weird world, and Chris Packham explains why.
Off the west coast of America sea stars are in trouble, tearing off their own limbs off which then wander away themselves.

In 2005, Oprah sat down with Naglaa Mohamed, whose daughter, Manar, was born with Croniopagus Parasiticus, or two heads. Doctors were then forced to perform a radical surgery, that no child had ever survived. Manar became the first baby in the world to ever survive this surgery, but sadly she passed away a year later from a brain infection. Here, take a look back at her story.
