Japan faces a new strong earthquake, says scientist

New strong earthquake could happen in Japan because of the weakness of aftershocks, said head of the laboratory of continental seismicity and seismic hazard prediction of the Institute of Earth Physics Alexei Zavyalov.

9.0-magnitude earthquake occurred in Japan on March 11, it caused a tsunami ten meters.

The epicenter was located 373 kilometers northeast of Tokyo, his focus lies at a depth of 24 kilometers. Soon, in the same area several more powerful aftershocks above magnitude 6.0.

Thinning of the crust of the ocean to complete their education in Ethiopia

Scientists have found that the main reason for taking place in the valley of the Ethiopian Afar geological events is the dramatic thinning of the crust. The article appeared in the scientific journal Nature Geoscience, and its summary results ScienceNews.

In 2005, it was established that in the valley of the Afar are processes that are closest (by geological standards) will lead to the formation of the future on the part of modern Africa's New Ocean. Then a few days along the East African Rift, mark boundaries of tectonic plates, a crack length of almost 50 kilometers and a

The area between the Salyan and Hajigabul region of Azerbaijan was a serious threat to the Earth’s crust

Karst holes

2.04.11.Ot territory of Salyan to Hajigabul there was a break in the earth's crust. APA, reported by the head of the department of seismology and geodynamics of the Institute of Geology Fakhraddin Gadirov.

Noting that the process began in March, Gadirov added that this information was provided to the institution of the Ministry of Emergency Situations, "5-10 cm eastern part of the territory referred sank into the sea. In some places there are small mud volcanoes. And the most important thing is that all this has led to the earthquakes in Hajigabul magnitude 3.5, 3.6 and

South Primorye shifted by 4 cm after the earthquake in Japan in 2011

Scientists have found that the crust of southern Primorye and Vladivostok in the earthquake in Japan March 11, 2011 shifted to four centimeters in the direction of the earthquake's epicenter, said on Thursday the press service of the Far Eastern Federal University (Palo), which conducted the study of the Earth's crust.

Eleventh March 2011 in the north-east Japan earthquake with magnitude 9.0, which was officially named the Great Earthquake. It caused a tsunami that reached a height of 30-40 meters. The disaster killed or missing, more than 19 thousand people. Nearly 380,000 homes were destroyed or destruction.

Instead of one of Africa will have two?

Australian researchers found that after a while Africa may split in two. They explored the rift (the boundary between two lithospheric plates) Rukwa in Tanzania and found that tectonic activity of the place is still very high. Curiously, all the processes occurring there, very similar to the beginning of the fault of the continent.

As we remember, 180 million years ago there was no Africa — the continent with South America, Australia, Antarctica, and the Indian subcontinent, Arabia, Madagascar and New Zealand was part of the supercontinent Gondwana. However, after 30 million years, the continent suddenly cracked,

The inner life of volcanoes

Two new studies at the University of Leeds, UK, on the inside of volcanoes may help scientists come closer to the prediction of powerful eruptions. The main work carried out in Afar, Ethiopia, and in Iceland, since that is where the mid-ocean ridge comes to the surface, which greatly facilitates the organization of observations.

Volcanic ridges occur when tectonic plateau crush or disperse. Magma, molten rock that seeps into fractures thinned crust in the form of lava, and solidify to form new crust. Accumulations of magma work as sewage systems, high pressure paving the way to the surface through underground

Disasters in Japan are associated with the movement of the earths crust

Its assessment of the natural phenomena in Japan gave Head of Meteorology SI "AHEM" Irina Truschina.

(Kazan, March 16, "Tatar-Inform", Irina Ignatieff). Disasters in Japan are associated with the movement of the earth's crust. Its assessment of the natural phenomena in Japan gave Head of Meteorology GU "Office for Hydrometeorology and Environmental Monitoring RT" Irina Truschina.

At the request of the Information Agency "Tatar-Inform" I.Truschina answered the question: Will the natural disasters that are happening now in Japan, to climate change on other continents?

Earthquake that took place in Japan, she says, are phenomena of a different nature. They

Japanese earthquake disturbed inhabitants crust

A powerful magnitude 9.0 earthquake Japan has led to the release of methane from oceanic crust to the east of the island — along with the microorganisms living in the cortex.

The earthquake, which took place March 11, 2011 off the Pacific coast of the Tohoku region, shifted the bottom 7 meters vertically and 50 meters horizontally. Within 36 days after this Sinsuke Kawaguchi and his colleagues at the Japan Agency for Marine-Earth Science and Technology took water samples from a depth of 5.7 km in four places Japan Trench near the epicenter.

They found a large column

Quartz weaknesses: Hosts Earthquake

Large concentrations of quartz — one of the most common minerals crust — can create it as a "weak point", which is easier to grow mountains and continents apart.

From the point of view of chemistry, quartz — surprisingly inert mineral, in pure form and in the other species (such as granite), it is up to 12% of the earth's crust. Quartz is found everywhere and in many different forms — from ordinary grains of sand to the semi-precious stones agate and amethyst. Moreover, the deeper mineral occurs, so it becomes softer and more "fluid" under the influence of
