Announcement: Shall we in the era of volcanic disasters?

31 May from 15.00 to 16.00 — a visit to the "MK" volcanologist Arthur Saltykov, chief researcher at the Institute of Earth Physics named Schmidt, doctor of geological-mineralogical sciences, professor.

Arthur Y. long worked in Iceland, where he studied the activity of volcanoes. During the online conference will discuss the causes of volcanic activity and, in particular, the Icelandic Grimsvotn, and how scientists are predicted end of the world, occasionally appearing in the media.

Grimsvotn volcano eruption could resume — volcanologists

Active Icelandic volcano Grimsvotn (Grimsvotn), because of which in a few days, flights were canceled in the UK, Germany and parts of Scandinavia, significantly decreased, but safe to say that the eruption has ceased, there is no way, said Dr. Martin Hensch (Martin Hensch) Volcanological Center, University of Iceland.

Grimsvotn volcano in southeast Iceland, the previous eruption which was recorded in 2004, became more active during the night of May 22. The smoke from the volcano rose to an altitude of 20 kilometers. Earlier Wednesday, Icelandic meteorologists said the Grimsvotn eruption stopped. In spring 2010, the eruption of another

Tungurahua volcano again showing signs of increasing activity

After a week of relative respite from 22:30 Monday Volcano Tungurahua, one of the largest active volcanoes in Ecuador, once again showing signs of increasing activity, the discharge column of ash and incandescent material that scatters from the crater in different directions and falls from up to 800 meters on the slopes of the mountain.

According to Daniel Andrade, volcanologist monitoring station Guadalupe Geophysical Institute (IG) in Pelileo, this new surge of activity was expected in view of the accumulation

Shiveluch in Kamchatka ejects ash to a height of 6 km

The northernmost active volcano of Kamchatka — Shiveluch — throws ash column to a height of 6 km, told RIA Novosti the Kamchatka branch of the Geophysical Service RAS.

Increased activity of Shiveluch volcano, whose height is about 3.3 thousand meters above sea level, was launched in May 2009. In the dome of the volcano is a normal eruption formed cleft depth of about 30 meters. For settlements eruption no danger, but plumes threaten aircraft.

"Emissions of ash to a height of 6 km and a cable, which runs to the east, was observed on the last day of

The world continues to live like a volcano

Disappointing forecasts come from the experts of the International Committee on Global Change of the geological environment — a new phase of growth of seismic activity. Therefore, in the next few years, the world, catastrophic earthquake. March events in Japan is just the beginning.

Next in line regions "Ring of Fire" — Indonesia, the Philippines, the west coast of North and South America. Could be disastrous situation in California, if activated one of the most seismically active faults in the world — San Andreas length of 1300 kilometers. And that could happen as early as 2013, experts say.

Will

Spain is waiting for eruption

In the Spanish Lorca May 11, there were two strongest earthquake in 50 years. Geophysicist, member of the Russian Academy of Natural Sciences Alexander Gorodnitsky told "Trud", why tectonic activity increased.

— DOES THE tremors in Lorca the March tectonic shift in the Pacific?

— No. Earthquake in Japan, even the power of 9 points could hardly lead to crowding-ku in Spain.

— What was the reason?

— Events in Lorca linked to the small collision Iberian and African tectonic plates (On the Iberian plate is Spain. — "Work"). Deal that at the Strait of Gibraltar and to the Azores

Increases the pressure inside the volcano Tungurahua, experts warn

The pressure inside the crater of the volcano Tungurahua increased because of rising magma, although in recent days, the release of gas and ash fell from the crater, according to the staff of the Geophysical Institute of Ecuador (IG). As explained by volcanologists, the observed decrease in emissions of ash does not mean that the current activity of the Colossus, which began on April 20 and the efforts of 29 April, began to decline.

As noted in yesterday's report, the increase of deformation within the crater, periodic severe tremors cliff face and the constant release of gases such as

Azerbaijan has several times increased seismic activity

Earthquake

Baku, November 19, SalamNews, Z.Ibragimhalilova. Azerbaijan increased seismic activity. As the SalamNews, according to published statistics, the number of aftershocks recorded earthquakes has increased several times.

For example, in 2009 the monthly average was recorded about 3 push in 2010 instruments recorded monthly 4.6 earthquake, and in 2011 — 7-8.

However, in January this year there were three push in February — 3 March — 9 April — 0 May — 33 June — 7 July — 2 August — 10 September — 7 October — 16 November — 14.

Ecuador volcanic ash falls asleep

 

In Ecuador, in the middle of April woke up one of the highest active volcanoes in the country — the volcano Tungurahua. From April 20 to the present time he is in a period of increasing their activity. All the while emitting ash from this colossus, which are estimated to have already considered some of the volume in 1999.Despite a rather cloudy day, in the afternoon over the crater Tungurahua can see a column of ash reaching heights of 2 to 12.7 km, while there was a strong tremor cliff face. Ashes already asleep nearby villages and forced the

Magma on the way: The levels of accommodation magma hot spots

They are called hot spots or Plumes — hot mantle flows move independently from the convection currents in the mantle. They are the least expensive, to measure the temperature of the planet, and vibration. The increase in seismic activity in these regions — the signal inside the planet, the magma pressure gradient increases.During earthquakes, it begins to rise in these regions, we know, but we do not have time for.The increase in volcanic activity in Iceland, Hawaii, and the recent earthquake on Easter Island, Tistan-da Cunha, Tonga-Kermadec arc, and now 4.6 earthquakes in the transition region Galapolos Triple signal planet,
