Erupting volcano casts shadow on Russian peninsula

14.05.2004


The most northerly active volcano on Russia’s Kamchatka Peninsula is once again erupting, dusting the surrounding snow-white landscape with a wide expanse of dark ash that is visible from 800 km away in space.


This reduced resolution Medium Resolution Imaging Spectrometer (MERIS) image was acquired 11 May 2004 and shows the Kamchatka Peninsula in Russia’s Far East. The erupting Shiveluch volcano is located towards the right of the peninsula about two thirds of the way up - around it is a circular band of dark ash from the eruption visible over snow.

This image of the Kamchatka Peninsula on Russia’s East Coast was acquired on 11 May 2004 by the Medium Resolution Imaging Spectrometer (MERIS) instrument on ESA’s Envisat satellite in reduced resolution mode.

Two thirds of the way up the Peninsula can be seen a roughly circular band of ash, and at the high point of this band is located the steep-sided 3283-metre-high Shiveluch stratovolcano. An aerial cloud of steam and possibly ash originating from the peak is also faintly visible against the ocean to the east of the Peninsula.


Part of the volcanic ’Ring of Fire’ chain located around the Pacific, Shiveluch – also known as Sheveluch - last erupted in 2001. After a two-year lull volcanic activity began again at the start of this year, and on 9 May the volcano underwent an explosive eruption, propelling ash and volcanic gases into the atmosphere up to eight km above sea level.

The locally-based Kamchatkan Volcanic Eruptions Response Team has observed a lava dome growing in the crater and warn that another explosive eruption could be due at any time. Strong volcanic tremors and surface earthquakes have been detected, while heavy mudslides from Shiveluch have also blocked roads in the area.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
