That is, after the eruption of the Japanese volcano, the Icelandic volcano erupted, and the disaster

Mondo Science Updated on 2024-02-13

A volcano near the town of Grindavik on the Reykjanes Peninsula in southwestern Iceland erupted in the early morning of February 8, and Iceland** declared a state of emergency. This is the third round of volcanic eruptions in the local area since December 2023, and it is difficult to ** the duration of the eruption at this time. Iceland is located in the volcanically active zone of the Mid-Atlantic Ridge, with many volcanoes and frequent geological activity, so it is very rich in geothermal resources.

Iceland is an island country located in the middle of the North Atlantic Ocean, and its full name is the Republic of Iceland. Its capital is Reykjavík. Iceland is also the second largest island in Europe, with a total area of about 103,000 square kilometers and a coastline of about 4,970 kilometers. Iceland has 116% of the land is covered by glaciers, and most of the area is between 400 and 800 meters above sea level. Iceland's climate is cold temperate and oceanic. The country is divided into 21 municipalities and 203 electoral districts. As of September 2023, the total population of Iceland is 3970,000 people.

In the mid-9th century, the Irish and Norwegians came to Iceland and became the first inhabitants of Iceland in history. Iceland established the world's first parliament, the Althingi, in 930. From 1262 onwards, Iceland was ruled by Norway and Denmark, respectively. Finally, on June 17, 1944, Iceland proclaimed the Republic of Iceland.

The Icelandic Meteorological Service reported that the eruption site was about 4 kilometres northeast of the town of Grindavik. ** Volcanic activity has torn a fissure about 3 kilometers long on the surface, along which red-hot magma is surging westward. ** at the scene showed that orange-red magma erupted from the cracks, reaching tens of meters high, which was especially noticeable at night, and smoke was also diffused in the air. About 3,800 residents of the town of Grindavik were evacuated before the eruption last December. A ** from the Icelandic Civil Protection told the Icelandic National Broadcasting Agency that it is believed that there was no one in the town of Grindavik at the time of the eruption on the 8th. "As far as we know, no one has returned home," the ** said. ”

The magma swallowed up a heating pipe, causing thousands of homes in several towns on the Reykjanes Peninsula to be left without heat. Many schools, gymnasiums and swimming pools were forced to close due to the lack of heating and hot water. The nearby Keflavík International Airport is currently operating as normal, with inbound and outbound flights unaffected, but the airport's hot water** has been disrupted.

Iceland's national broadcasting authority reported that the Blue Lagoon geothermal hot springs near the erupting volcano have been forced to suspend operations and all visitors have been safely evacuated. Later in the day, the road was covered in magma, blocking access to evacuation.

This eruption is a fissure eruption and usually does not result in large-scale** or large amounts of ash spreading into the stratosphere. The first two eruptions occurred on December 18 last year and January 14 this year, respectively, due to the early evacuation of residents, fortunately the eruptions did not cause **people**. However, a series of ** and volcanic activity caused cracks in the ground and some houses burned down.

By the afternoon of February 8, the eruption had eased in force, but its magma had not stopped surging out of the cracks.

The reasons for the frequent eruptions of Icelandic volcanoes can be attributed to volcanic geological activity, abundant geothermal resources, volcanic tectonics, and plate movements. Iceland is located on the Mid-Atlantic Ridge, an area that is one of the most active tectonic plates on Earth and one of the largest volcanic activity zones in the world. This has led to the instability of Iceland's geological formations, which has led to frequent volcanic eruptions, but not as much damage as Japan's volcanic eruptions.

On the first day of the 2024 New Year, a 7 on the Richter scale took place in the Noto area of Ishikawa Prefecture, JapanLevel 6 of intense**. This ** caused a tsunami and fire, which made the otherwise joyful New Year's atmosphere instantly depressing and terrifying. The whole area is littered with rubble, and people have to face the pain of life and death.

At around 3 p.m. local time on January 1, the Suwa no Seshima volcano in Toshima Village, Kagoshima Prefecture, Japan, also erupted. Thick smoke soared into the sky, and the plume of smoke rose to a maximum of 1,600 meters. By 9 p.m., a small amount of volcanic ash began to fall on the island. The alert level around the crater is classified as level 2, and the Meteorological Observatory has also called on local residents to be alert to large pieces of volcanic debris near the crater. It was not until 10 a.m. on the 2nd that the Japan Meteorological Agency lifted all tsunami warnings. As of 3:30 p.m. on the 2nd, a total of 48 people had died on the Noto Peninsula**: 20 in Suzu City, 19 in Wajima City, 5 in Nanao City, 2 in Anamizu Town, and 1 each in Haza City and Shiga Town. In response to the eruption of the volcano, it was a relentless catastrophe that caused huge losses to people's lives and property. However, in the face of disasters, people have shown tenacious vitality and the spirit of solidarity and mutual assistance. As long as the crowd is prevented and evacuated in time, the number of people** can be reduced to a minimum. Of course, there are still unique geographical factors that explain the frequent occurrence of volcanoes in Iceland.

First of all, the Icelandic crust is constantly being pulled apart and pushed, which is the result of tectonic faults between the North American and Eurasian plates, which push each other. This plate movement leads to cracks in the earth's crust and upwelling of magma in the lower part of the earth's crust, which accumulates too much magma and leads to volcanic eruptions. It is because of this plate movement that the volcanoes on Iceland are also classified as fracture volcanoes, which usually erupt with less ash compared to other types of volcanoes.

Secondly, Iceland is rich in geothermal resources. Iceland is located on the Mid-Atlantic Ridge, a chain of volcanoes that surround the Earth, and the magma gushing out of the volcanic shores is one of the main reasons for the abundance of geothermal resources. Underground hot water in Iceland is also due to the presence of geothermal resources. This geothermal activity is closely linked to the zone of active plate movement in Iceland and has had an important impact on volcanic activity.

In addition, Iceland's geological formations are also one of the reasons for the frequent eruptions of volcanoes. Iceland is located on the Icelandic Jestavot Crustal Plate, an ancient volcanic island covered by some crustal plates called the "Icelandic Crust". This crustal plate is thin and brittle, can easily **, and can easily lead to magma eruptions. In addition, the earth's crustal plates near Iceland are also prone to slippage, which leads to sustained activity.

In general, the frequent eruptions of volcanoes in Iceland are mainly due to the plate movement of the Mid-Atlantic Ridge, the abundant geothermal resources, and the geological formations of Iceland. Volcanic eruptions in Iceland can cause some damage, but Iceland** will take measures to ensure the safety of local residents depending on the scale and impact of the eruption. In addition, we must also learn to respect nature, protect the natural environment, natural disasters and man-made disasters are sometimes unavoidable, but we can use scientific and technological means to warn in advance as much as possible, prevent problems before they occur, and reduce personnel.
