18000 earthquake: Reykjavik was as frightened as a bird. Will Iceland volcano erupt?

Iceland should be the happiest country in the world, with a per capita GDP of $73,000 in 2020, ranking fourth in the world. All energy comes from green and sustainable energy, 70% from hydropower and 30% from geothermal energy. You can go to a hot spring anytime. Iceland has unique natural scenery and is almost a must-see location for major documentary channels!

But beautiful and happy Iceland, while enjoying the gift of nature, must bear the roar from the inside of the earth, because the 40,000-kilometer mid-Atlantic ridge passes through Iceland, and even Iceland is the product of the extrusion of the mid-Atlantic ridge. The volcano on the island is the way for the earth to say hello to Icelanders!

18000 earthquake: Reykjavik, the capital of Iceland, was shocked like a bird.

According to the statistics of the Icelandic Meteorological Bureau (IMO), in the past week, more than 18000 earthquakes occurred in Reykjavik Peninsula, where the capital of Iceland is located. The smallest can only be sensed by seismographs, but the largest reaches 5.6 on the Richter scale, which is enough to cause great damage!

This is because there are two volcanoes in janus Peninsula, namely kirill Volcano and Fagra Darce Fial Volcano. The recent frequent volcanic earthquakes indicate that the future may erupt at any time!

Kilier volcano is unknown, with an altitude of only 378 meters and an area of about 0.773 square kilometers. Although it is not high, it is highly recognizable on the endless Janas Lake Peninsula, because its conical gray-black protrusion has become a landmark often used by fishermen and sailors, which is rarely known by outsiders, but it has become "popular" in recent days!

Because the local Víkurfréttir news agency in Reykjavik, southwest Iceland, installed a live video camera on Monday night, the recent frequent earthquakes in Reykjavik janus Peninsula are a sign that Mount Kyril is about to erupt. Its last eruption was in12nd century.

The live video of the camera hasn't exploded at least. The screenshot time is 2021March 5 19:22.

You can still hear a lot of wind in the live broadcast, and it seems that you can still hear the sound of raindrops scratching. You can't see whether it is raining from the picture, but you can see the fuzzy shadow formed by raindrops from the foreground of the lens.

The mysterious Kerrill volcano

It will bear the roar from 12 century, and the Icelandic people will soon tremble for it! Because Mount Kyril is only 23 kilometers away from the Icelandic capital, if the eruption scale is as big as Eyjafjallajokull volcano in 20 10, not only the Icelandic capital will be shrouded in volcanic ash, but also the global aviation industry will be seriously affected!

The eruption of Eyjafjallajokull volcano affected 6.5438+million people.

Eyjafjallajokull volcano is located under the Eyjafjallajokull ice sheet in southern Iceland, and it is a glacier-covered volcano. On Christmas Eve in 2009, thousands of small earthquakes were detected in this area, and the focal point was 7- 10 km underground. 20 10 On February 26th, Iceland Meteorological Bureau recorded abnormal signs of crustal expansion, and geophysicists judged that magma below was entering magma chamber.

20 10 On March 20th, it broke out in a mountaineering area in the east of Eyjafjallajokull crater, but the scale was not large. On April 14, the volcano erupted again, but the scale was ten times larger than the previous one. This outbreak has two fatal effects:

Glacier meltwater

Volcanic ash affects air transportation.

Because Eyjafjallajokull volcano is under the ice sheet, although the two eruptions did not occur under the ice sheet, the ejecta melted a large number of glaciers, leading to the flooding of glacial meltwater. Fortunately, Iceland has a vast territory and a small population. The Icelandic government evacuated 800 residents.

Volcanic ash has a great influence. Iceland is located in northern Europe, the hinterland of the North Atlantic, and it is the only way to Europe and America. A large number of volcanic ash entered the stratosphere for a long time, which led to the diversion or grounding of flights between Europe and the United States. Because volcanic ash floats and spreads, the whole North Atlantic is not suitable for passenger flights.

Because volcanic ash will be sucked into the engine of a passenger plane, it will cause damage to the engine blades and even cause the plane to crash and cause death. Airlines don't joke about passengers' lives. Of course, once it crashes, small airlines may lose all their money. Therefore, a large number of flights were cancelled, affecting about 6.5438+million passengers during the eruption!

On April 2010 18, some flights in Europe resumed.

At 20 10 on April 20th, European flights basically resumed.

Will Mount Kyril be that serious?

According to a series of recent earthquake activities, the Icelandic Meteorological Bureau has judged that the magma below Mount Kyril may be entering magma chamber and may erupt at any time in the future. However, according to the analysis, this volcanic eruption may not be very high, but it is more likely that there will be a lava flow, just like the lava flow of Kilauea volcano!

Moreover, there is no glacier in Mount Kyril, and it will not cause flood melting. If it breaks out, it may cause a wave of onlookers. After all, it is located in Kyril Park, and the Fagradalsfjall volcano is in a similar situation!

But is the volcanic eruption accurately predicted again? What if both volcanoes surprise Icelanders or people all over the world?

Further reading: Why are there so many geothermal and volcanoes in Iceland?

There are always 200-300 large and small volcanoes and 40-50 active volcanoes in Iceland. There are Eyjafjallajokull volcano, Huanadals volcano, catra volcano, Laki volcano and Hekla volcano. Of course, there is geothermal energy everywhere. In Iceland, it is even difficult to find a well that is not hot. Of course, this is a joke, so why are there so many geothermal volcanoes?

Iceland is a hot spot on the earth, and the mid-Atlantic ridge passes through here. This is because the thermal convection of the mantle rises at the center of the mid-Atlantic ridge. After the magma gushed out here, it quickly cooled into basalt and formed a new ocean crust. For example, the mid-Atlantic ridge produces a new ocean floor every year, which keeps America and Europe away, with an annual speed exceeding 10cm!

Iceland, on the other hand, is the outcrop area of the mid-ocean ridge, where magma keeps flowing. Of course, this is a high-risk area for volcanoes and earthquakes. Another high-risk area is the fault zone on the plate edge and inside the plate, such as Japan on the Pacific plate and Eurasian plate edge, which is also a country with many volcanic earthquakes and hot springs.
