Map of volcanoes in Northern Eurasia

Specialists of five Russian academical institutes including three academicians and two Corresponding Members of the Russian Academy of Sciences drew up the first map of up-to-date volcanism in Northern Eurasia. The map reflects distribution regularities in volcanic active regions formed in the last 10-15 million years in this part of the Earth.

Volcanic regions are connected with young mountain systems that are located at the periphery of Eurasian platform. The major part of these regions lies in the territory of Russia. Volcanic regions differ not only by territory, but also by the age, activity, erupted rock and other peculiarities. The researchers mark out volcanic regions of mid-oceanic ridges, island arks, continental collision zones and intraplatform ones.

The most active are island arks volcanoes, including, the Kuriles and Kamchatka islands. These are quite young volcano regions, they are only three million years old, and the contemporary relief of the area is determined mainly by volcanoes formed within the last 40-50 thousand years. There is not a single year without an eruption taking place in the region.

This volcanic region is known for big conic volcanoes such as Klyuchevskaya Sopka, Avachinsly, and Kronotsky, which erupt hundreds of cubic kilometers of volcanic products. Klyuchevskaya Sopka’s eruption happen once in several years, but for multiple volcanoes, calm periods can last for centuries. If a volcano has not erupted in 3,000 - 3,500 years, the volcano is dead.

Volcanoes of the continental collision zone (i.e. the zone of where the Eurasian platform collides with the Arabian-African and the Indian platforms) behave more calmly. The zone stretches from the central regions of the Tibet in the east through Pyrenean peninsular in the west. The scientists distinguish two branches: the Asian and the Anatolian-European ones.

The Asian branch combines volcanoes allocated inside the Asian continent, in the zone of collision between the Indian and the Arabic platforms. The larger volcanoes include Elbruz, Demavend, Sahand and Bazman. Volcanoes of this type erupt occasionally, with periods of calm lasting from several thousands of years to dozens of thousands of years.

Volcanoes of Anatolian-Balkan branches stretch along the northern coast of the Mediterranean Sea. In this region, there are both lava table lands and big volcanoes, among which are also infamous Santorin and Vesuvius volcanoes. Among intraplate volcanic zones, volcanoes of Eastern and Central Asia draw attention. These areas are predominated by lava dome folds and table lands that appear in case of interstitial lava flow. Low volcanic activity also takes place in Chukotka.

Two transcontinental submeridional rift zones are singled out by the scientists into a special group of intraplatform volcanic regions. One of them crosses Central Europe and Mediterranean, and goes off to the territory of North-Western Africa down to Gulf of Guinea. The other zone can be tracked from the Caucasus foothills (the region of Mineralnye Vody) through Tanzania. Both zones retain volcanic activity particularly at the intersections with the continental collision zones. Etna, Vesuvius, Tendurek, Nemrut, Elbruz and Kazbek volcanoes erupted back in historic times.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
