Scientists note increased volcanic activity over the past 50 years

The frequency of eruptions of volcanoes on Earth over the past half-century has increased significantly, the planet has entered a period of increased seismic and volcanic activity, said chief researcher at the Institute of Physics of the Earth named Schmidt, volcanologist Arthur Saltykovsky.

"Statistics … indicates that the last time since the middle of last century and the beginning of century, volcanic activity has increased markedly," — said the scientist during an online conference on the site of the newspaper "Moskovsky Komsomolets".

According to him, the increase in the number of eruptions can be "linked to the overall activity

Underwater volcanoes erupt differently

Macauley Island — caldera, formed after the eruption of an underwater volcano of the same name 6100 years ago (here and below the image of the authors.)

January 21, 2013. Until now, scientists were divided eruption into two categories: violent (explosive) and effusive. The first type involves adorable kids emission of ash and rock fragments high into the atmosphere (for example, eruption of Mount St. Helens in 1980). The second — the soft glow of red lava streams that irrigate the slopes of the volcano (this, for example, constantly going on in Hawaii).

To get to the unusual

Scientists argue that the eruption of the volcano Mount Vesuvius could start at any moment

September 30, 2013. According to the latest research, the most famous volcano in Europe is up and is now ready to fill in the neighborhood of lava and ash fall asleep. In one of the research centers in Italy have long been studying a volcano that wiped out Pompeii two thousand years ago.

The Kamchatka Peninsula and the North Kuril Islands is marked increase in seismic activity. Especially dangerous is the volcano Nameless, which has awarded the highest "red" code of danger. Seismologists believe that the eruption could begin at any time.

The volcano is located at 55 ° 58'N, 160 ° 36'E, its height is 2.895 meters above sea level. Nameless is considered one of the most dangerous volcanoes in the modern world. Its seismic activity started to progress in the middle of February. To date, the lava dome in the crater of the volcano rose

Volcano Rokatenda proved his unpredictable

September 7, 2013. Photos of Indonesian active stratovolcano Rokatenda made before and after its last eruption, according to the unpredictability of volcanic eruptions. Once this volcano on the island of Palu intensified in late 2012, his ashes and lava mainly directed to the south from the top of the mountain. However, August 10, 2013 the volcano suddenly threw another batch of ash and volcanic rocks to the north from the top, resulting in a small village situated on the coast of killing six people.

Photographs taken satellite "Landsat-8", clearly shows the wide gray stripe that tapers to the north-west, repeating

In Alaska, found a huge underwater volcano

May 17, 2013. Two geologist with Fr. The Prince of Wales and the city of Anchorage in the analysis of a fragment of the image between the hydrographic Thorne Arm and found it Raderdom design consisting of a large hill, and next to it two dome-shaped structure. After some discussion, the geologists concluded that the elevation and two adjacent dome is nothing like oceanic volcano caused quite close to the national park Misty Fjords.

Most likely, the formation of an open Alaska volcano occurred as the famous scientist Sarts volcanic island near Iceland. In 1960 the Icelandic underwater

Mount Cleveland volcano dome rose 25%

Mount Cleveland volcano dome rose 25% Danger Zone

On 6 February the dome of the most active volcano in the Aleutian Islands rose by only 40 meters. However, over the last week, it increased to 50 meters, which indicates a possible eruption in the next few days.

Fig. 2. Satellite image of the top of Cleveland. Inside the crater with a diameter of about 200 m see a small volcanic dome. 10/02/2012.

Prior to that, a massive volcanic dome, which occupies most of the crater, the eruption was destroyed on 25 and 29 December 2011. Cleveland's new dome continues to

Etna volcano eruption

Eruption of Etna Natural Disasters

After a 12-day Strombolian activity in the southeast of Etna February 9, 2012 in one of the craters, a series of paroxysmal eruptions, the second in 2012. Although the event was less powerful, but it lasted more than 5 hours. Interrupted activity of the 8 February, reaching its peak at night to the eruption of lava up to a distance of 500 meters. Rising column of ash several kilometers into Catania airport forced to cancel all morning flights. At some explosions from the crater were ejected volcanic bombs, most of which came back into the
