eyjafjallajökull plate boundary

The seismic activities were in horizontal sill intrusions at 4.5 – 6.3 km in depth below the southern flank (Pedersen and Sigmundsson, 2004, 2006; Hooper et al., 2009; Sturkell et al., 2010). The eruption caused major disruption in the country as well as across the world. … It is an elongated, broad cone of about 1650 m height. Increased unrest and more risk of eruption, or eruption is occurring, but violent explosive activity has no slowed or stopped. You can view samples of our professional work here. The diverging Eurasian and North American plates caused the eruptions of Eyjafjallajökull (in 2010) and Bardarbunga (in 2014). As for moderately active volcanoes such as the Eyjafjallajökull volcano less is known about the deformation of these types of volcanoes (Sigmundsson et al., 2010). Discharged increased again, Eruption declined until it eventually stopped, More explosions however they had a small amount of magma. The Eyjafjallajökull volcano erupted in 920, 1612 and again from 1821 to 1823 when it caused a glacial lake outburst flood (or jökulhlaup). Plate Tectonics explains what happens as the North American and Eurasian Plates pull away from each other; new crust is formed from erupted magma along either side of the ridge. The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events. Iceland lies on the Mid Atlantic Ridge, a constructive plate margin seperating the North American plate and the Eurasian plate. This highlights the need to examine such eruptions and gather how the eruptions took place and the affects that they can cause. The volcano itself has a large ridge shape that’s in a lengthened east west direction (Jónsson, 1988). However, the volcanic ash cloud affects were affected greatly by the weather as the prevailing winds, caused large dispersion to the south and south-East of the Volcano. First, find Iceland on the map. Shortly before midnight on March 21st, a 500-600 m long fissure stretching north east to south west opened up on the north-eastern flank of Eyjafjallajokull on the ice-free Fimmvorduhals ridge, which divides this icecap from Myrdalsjokull its 560 km² neighbour to the east. Melt composition from Benmoreite to Trachyte. The second eruption occurred on the summit of the volcano and started at 3.30pm on 14th April 2010. The North American plate moves west, whilst the Eurasion plate moves East, creating a divergent plate boundary moving apart at rates of 1-5cm per year. During this monitoring of the 1999 swarm a modelled intrusion with a circular sill with a volume of 0.030 ± 0.007 km3 at 5.0 ± 1.3 km depth was recorded (Hjaltadóttir et al., 2015). Examples of these are Eyjafjallajökull The divergent plate boundary between North America and Eurasia has a relative motion of approximately 18–20 mm yr −1 in a direction of 102–104° E of N (DeMets et al. Disclaimer: This work has been submitted by a student. But lies within a series of high rising volcanoes that’s influenced by a secondary rift zone (REF). Figure 1: Distribution of Ash across Europe that caused international attention due to this major secondary impact of the Eyjafjallajökull eruption to the aerospace industry. Other examination from the Global Positioning System GPS revealed that a 0.05km3 magmatic intrusion grew within 3 months (REF). The coupling mechanism between the volcanoes remains enigmatic. Yet trauma response teams from the Red Cross were at evacuations and in community centres at the time of the eruption (Carlsen et al., 2012). Pressure perturbation in the mantle may also affect the magma sources of both volcanoes. As the ash can cause high damage to airframes, avionics and engines of civil jet aircraft. Registered office: Venture House, Cross Street, Arnold, Nottingham, Nottinghamshire, NG5 7PJ. (convergent or divergent?) This caused a mix of magma and ice which causes the explosivity of a volcano to increase in intensity (Sammonds, P., McGuire, B., Edwards, 2011). The Eyjafjallajökull volcano, one of the oldest active volcanoes in Iceland, is located in the volcanic flank zone of South Iceland, a few tens of kilometers off the nearest branch of the mid-Atlantic plate boundary. It’s one of several volcanoes that stretch along the fault lines of the tectonic plates. There is evidence for similar behaviour in the two other known eruptions of Eyjafjallajökull in Historic time, those of 1612 and 920. Iceland has a high concentration of active volcanoes due to its location on the mid-Atlantic Ridge, a divergent tectonic plate boundary, and also due to its location over a hot spot. The plate boundary in Iceland is expressed by different segments and is divided into the Northern Volcanic Zone (NVZ), the Western Volcanic Zone (WVZ), and the Eastern Volcanic Zone (EVZ) (Einarsson and Saemundsson, 1987). Other ways to monitor and predict future eruptions: The eruption in 2010 was the culmination of 18 years of unrest that was alternating in strength this shows the importance of monitoring volcanoes over weeks to years to see signs of potential eruptions. Saemundsson, 1978), and their activity is only affected slightly by the plate movements. An E-W trending rift zone transects the volcano, most eruptive fissures and crater rows trend E-W, but occasional radial fissures are observed around the summit area. Eyjafjallajökull is a stratovolcano. These volcanic signs can indicate the reawakening of volcanoes, however these short term eruptions may be underestimated and difficult to prepare for (Sigmundsson et al., 2010). The volcanic edifice is an elongated, flat cone of about 1650 m height. Following the last eruption in 1821 the volcano had 170 years of dormancy which is normal for this volcano as its usual for it to have low levels of activity with it staying relatively quiet between its intrusion and eruption phases (Soosalu et al., 2006; Jónsdóttir et al., 2007; Jakobsdóttir, 2008). On the 18th April a change occurred that was a lower discharge phrase this lasted to the 4th May, the melt composition was less silicic than before as it reduced from around 60% to 58% and the magma discharge also dropped (Ref). Many of its slopes have been eroded down by the glaciers and rivers that run down from the ice sheet that peaks the volcano (REF). The activity of a volcano can influence the prediction of the eruption as a lot more is known about the volcanoes that erupted more frequently. The plate boundary is a Divergent boundary where the North American and Eurasian plates that move away from each other. It’s where the North American and Eurasian plates meet, and runs for 10,000 km (16,000 miles) along the ocean floor. Agreement NNX16AC86A, Is ADS down? The Volcano received a large media response and was categorized as a VEI of 4 on the Volcano Explosivity Index (Sammonds, P., McGuire, B., Edwards, 2011). Health effects of the local communities can also be reduced by well-developed houses as houses within Iceland generally have windows and doors that are insulated well so shut tightly and therefore can provide protection from health effects caused by ash (Carlsen et al., 2012). This developed into an official eruption that started on the 20th March and lasted around 6 weeks (REF). 21 March 2010. This phrase of the eruption being very violent for the size of the volcano was a result of the volcano being a Phreatomagmatic Eruption. Radar Techniques are the conventional method to monitor volcanoes however they cannot detect ash particles (Prata and Tupper, 2009). As these two plates move apart, magma continually wells up along the ridge, creating new sea floor. However, the Eyjafjallajökull Volcano is situated just beyond the propagating rift of plate spreading in Iceland. Started: April 14th, 2010 Ended: June 23rd, 2010 . This was an outcome of the eruption arising within an ice capped caldera. Plate Boundaries; Volcanoes. This movement was first recorded in 1994 when a period of seismic observations was recorded by seismic and geodetic measurements. The plate boundary is a Divergent boundary where the North American and Eurasian plates that move away from each other. However, this was still not successful enough in warning airlines of the possible threat. This inspection of the earthquake revealed that there was a small net volume of magma from the shallow depth of the mantle. Any opinions, findings, conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of UKDiss.com. Volcanoes can be monitored using varies techniques to estimate when an eruption will occur and what hazards it will present.

The health affects can be shown to not be just contained within the Iceland. Eruption not occurring, either as normal background state or an eruption has stopped from a recent eruptive period. This is not an example of the work produced by our Dissertation Writing Service. Then again in 1612 when a possible summit eruption arose (Jónsson, 1774; Larsen et al., 1999), and then in again 1821 when the volcano last erupted before 2010 eruption (Thoroddsen, 1925). Abstract — The Eyjafjallajökull volcano, one of the oldest active volcanoes in Iceland, is located in the vol- canic flank zone of South Iceland, a few tens of kilometers south of the nearest branch of the mid-Atlantic plate boundary. Eyjafjallajökull consists of an elongated ice-covered strato volcano with a 2.5-km-wide summit caldera.

However, the Eyjafjallajökull Volcano is situated just beyond the propagating rift of plate spreading in Iceland. The March event forced a brief evacuation of around 500 local people,but the 14 … The plates are moving apart at a rate of 1-5cm a year. The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative The summit of Eyjafjallajökull reaches an elevation of 1,666 metres (5,466 ft) and the ice cap itself covers an area of about 100 square kilometres. The continents are stuck on tectonic plates and move along with them. The immediate build up to the eruption started in January with an increased activity of phrases of seismic Earthquakes as well as volcano uplifting suggesting magma movement towards the surface (Hjaltadóttir et al., 2015). This is done by looking at details of eruptions and see the causes and impacts they caused. The deformation in this instance was rapid before the first eruption when it reduced 0.5mm per day after the 4th March. Tours to Iceland; Nachrichten zum Eyjafjallajökull: Mi, 9. These effects were unprecedented from the modest size of the volcano as such damage was not predicted. Eyjafjallajokull is located in Iceland on the Mid-Atlantic-Ridge which separates the North American and Eurasian plates. The EVZ and the WVZ are connected by the South Iceland Seismic Zone (SISZ). Plans to mitigate the effects of eruptions on air traffic have been attempted by the International Civil Aviation Organisation (ICAO) that use advice from the World Meteorological Organisation to keep Aircraft away from ash clouds by advising international airlines of ash clouds (Sammonds, P., McGuire, B., Edwards, 2011). The volcanoes of Iceland include a high concentration of active ones due to Iceland's location on the mid-Atlantic Ridge, a divergent tectonic plate boundary, and its location over a hot spot.The island has 30 active volcanic systems, of which 13 have erupted since the settlement of Iceland in AD 874.. Of these 30 active volcanic systems, the most active/volatile is Grímsvötn. Areas were flooded because of the glacier melt water which lay above the volcano. However, the Eyjafjallajökull eruption highlighted problems in this system and the need for it to be globally implemented across the globe. Convection currents are driving apart the North American plate and the Eurasian plate.

Iceland Greenland Eyjafjallajokull volcano ASH CLOUD! It erupted three times in 2010—on 20 March, April–May, and June. Free resources to assist you with your university studies! But further forecasting of the potential paths of ash clouds and the secondary impacts they can cause. These make up the Mid-Atlantic Ridge and has created the island of Iceland from two different types of volcanism. Eruptive fissures on the west flank are curved and tend to follow the topographic gradient. A 100-200 m thick glacier covers the upper part of the volcano and its elliptical 2.5-km-wide summit crater or caldera. Eyjafjallajøkull volcano (Iceland): low activity resumes. A tectonic plate floats loose from other tectonic plates but comes close to them and interacts with them where their edges meet, like underneath Iceland. As the plates move apart magma fills the magma chamber below Eyjafjallajokull. As well a contraction from 2000 to 2009 was recorded at the southern flank at a volume of 0.0015 ± 0.0003 km3/year at 5.5 ± 2.0 km in depth(Hjaltadóttir et al., 2015). From the 5th to 17th May the volcano became even more explosive, with the melt composition from Benmoreite to Trachyte. Their magmatic sources, however, appear to be chemically separated in spite of apparent sympathetic behaviour of the two volcanoes. The data shows a pipe like structure northeast of the summit crater, this shows the path of the magma from the base of the crust to the upper crust and into an intrusion (Hjaltadóttir et al., 2015). More Explosive. Iceland rests along the Mid Atlantic Ridge, a divergent tectonic plate boundary at the bottom of the Atlantic Ocean. Starting in the Arctic Ocean, it goes all the way to nearby the southern tip of Africa. How far did the volcanic ash cloud from the eruption travel? However other hazards were recorded further away from the eruption caused by ashfall from the volcano. The explosive action was relatively week but produced 2 to 4km high plumes. The rather mild activity of Eyjafjallajökull (3 eruptions in 1100 years) stands in strong contrast to that of the neighbouring volcano Katla, which is one of Iceland‘s most active volcanoes. The eruption in Iceland caused many effects that affected people nationally and internationally from primary and secondary hazards. The plate boundary is a Divergent boundary where the North American and Eurasian plates that move away from each other. The Eyjafjallajökull volcanic system is one of over 30 presently active volcanic systems in Iceland (Figure 1). I'm Stuck - GCSE and A-Level Revision 187,093 views. Eruption is looming with increased volcanic activity, or eruption taking place with significant emission of volcanic ash into the atmosphere. The volcano is on the island of Iceland, which is part of Europe and situated immediately South of the Arctic Circle.•. plate boundary, such as the Askja and Kverkfjöll fis- sure swarms in the Northern V olcanic Zone (Figure 1) contain long normal faults and open fissures, in ad- It is a relatively small volcano, and is located W of Katla volcano. More disruption was caused to flights was due to airlines having limited preparation, as it caught both airlines and public by surprise even though the volcano had been erupting for around a month before the airspace was suddenly closed on the 15th April by the UK National Air Traffic Control when they banned all non-emergency flights across the UK (Sammonds, P., McGuire, B., Edwards, 2011). It is situated on the mid-Atlantic ridge, between the Eurasian and north American plate.It is a constructive plate boundary. During the 1996 swarm it indicates that tension was building suggesting magma was intruding up into the base of the crust, however no uplift was recorded (Hjaltadóttir et al., 2015). The Eyjafjallajökull volcano erupted in 920, 1612 and again from 1821 to 1823 when it caused a glacial lake outburst flood (or jökulhlaup). VAT Registration No: 842417633. Eyjafjallajökull products have an alkaline composition, similar to other off-rift volcanoes in Iceland. The divergent boundary, called the Mid-Atlantic Ridge, that runs through the center of Iceland occurs because two plates, the North American Plate and the Eurasian Plate, are pulling away from each other. One volcano may be triggered by the other by direct dike or sill injection. The volcano went through a small subglacial stage when the eruption melted through the glacier of 200m of ice which took 3 to 4 hours (Gudmundsson et al., 2012) and this created large amounts of meltwater that caused flooding nearby . These eruptions were preceded by significant rifting and cracking on the ground surface, which are also emblematic of diverging plate movement. These floods were known as the jo¨kulhlaups or glacial outburst floods that occurred on the 14th and 15th of April (Gudmundsson et al., 2012). The volcanic edifice is an elongated, flat cone of about 1650 m height. Mixing of lava types (rhyolitic and basaltic). This was due to the ash produced from volcano as it caused major chaos to air traffic across Europe. Interactions of tectonic plates are believed to be the main reason of most earthquakes and volcanic activity on the Earth.
