The impact of secondary mineral formation on Na-K-geothermometer readings: a case study for the Valley of Geysers hydrothermal system (Kronotsky State Nature Biosphere Reserve, Kamchatka)

open access: yesЗаписки Горного института, 2023
The temperature in the Valley of Geysers (Kamchatka) geothermal reservoir calculated using the feldspar Na-K-geothermometer has been steadily increasing over the past 10 years on average from 165 to 235 °C, which is close to the temperature values of a ...

Klyuchevskoy Volcano: new flank eruption named after G.S. Gorshkov, 2021 (Kamchatka)

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2021
On February 18, 2021, a flank eruption started on the north-western slope of the Klyuchevskoy Volcano (Kamchatka, Russia). Cinder cone was formed at the altitude of 2 850 m above sea level, from which a lava flow was spreading north-west.

Testing asteroseismology with Gaia DR2: Hierarchical models of the Red Clump [PDF]

open access: yes, 2019
Asteroseismology provides fundamental stellar parameters independent of distance, but subject to systematics under calibration. Gaia DR2 has provided parallaxes for a billion stars, which are offset by a parallax zero-point.

Seismology in Italy [PDF]

open access: yesNature, 1889
I WAS glad to see that Prof. Grablovitz had laid claim to attention for some of his other memoirs which I had not at that time seen, and which are of much value. I would especially draw the attention of seismologists to his study of the relationship of temperature and outflow of a thermo-mineral spring at Porto d'Ischia to the tides and barometric ...

Models of the macroseismic field earthquakes and their influence on seismic hazard assessment values for Central Asia

open access: yesГеодинамика и тектонофизика, 2020
Seismic intensity assessment in points of a macroseismic scale plays an important role for researching the seismic history of areas characterized by active seismicity, as well as for construction (and updating) of seismic zoning maps in various scales ...

Bayesian Coronal Seismology

open access: yes, 2017
In contrast to the situation in a laboratory, the study of the solar atmosphere has to be pursued without direct access to the physical conditions of interest. Information is therefore incomplete and uncertain and inference methods need to be employed to

Magneto-seismology: effect of inhomogeneous magnetic field on transversal coronal loop oscillations [PDF]

open access: yes, 2008
The extreme-ultraviolet (EUV) imagers onboard the planned Solar Dynamics Observatory (SDO) and Solar Orbiter (SO) will offer us the best chance yet of using observations of post-flare loop oscillations to probe the fine structure of the corona.

Seismology of active stars

open access: yes, 2012
In this review we will discuss the current standing and open questions of seismology in active stars. With the longer photometric timeseries data that are --and will become-- available from space-missions such as Kepler we foresee significant progress in

The effect of elliptic shape on the period ratio P-1/P-2 of emerging coronal loops [PDF]

open access: yes, 2009
Aims. We determine the effect of an elliptical shape on the period ratio for the standing transversal oscillations of a longitudinally stratified coronal loop throughout its emergence from the low solar atmosphere into the ubiquitously magnetised corona.
