This paper reports a study of the Rikord volcanic massif. The massif consists of four volcanic edifices that coalesce in their bases, and is most likely Quaternary. The massif discharged basaltic and basaltic andesite lavas during its earlier life. The observed high natural remanent magnetization that was found in dredged rocks is due to high concentrations of single-domain and pseudo-single-domain grains of titanomagnetite and magnetite. We have identified the directions of the conduits and the presence of peripheral magma chambers. A 3D model has been developed for the central part of the Rikord volcanic massif; the model includes ten large disturbing magnetic blocks that are most likely cooled, nearly vertical, conduits.

The authors have studied the flat-topped Berg submarine-volcano. The volcano likely used to emerge above sea level in its past history, but suffered the top attrition subsequently. The edifice is composed as by dense rocks with prevailing andesibasalts and basalts, so by mouldy volcanic rock formations. The most magnetized lava flows effused near the top on the western slope after the volcano had sunk. These flows are possibly composed by basalts and are the youngest within the edifice.

The paper presents the results from investigation of remnant magnetization of submarine volcanic edifices within the Kuril island arc (KIA) based on data on hydromagnetic survey using software IGLA. Magnetic orientations of remnant magnetization of the studied submarine volcanoes within KIA differ from those of the modern geomagnetic field. The authors suggest that submarine volcanic activity coincided with the periods of worldwide geomagnetic disturbance.

This stady has proved that the EPR technique can be used to date volcanic formations within the Elbrus Volcanic Center (EVC) by investigating rock-forming quartz in volcanites, xenoliths of Paleozoic granite contained in these, and quartz in underlying older, metamorphic lavas. This is the firts time in Russia that the EPR dating technique has corroborated cycles of activity in the behavior of the Elbrus Volcanic Center previously identified from geological data, has determined the relevant time intervals, and deciphered the history of this stratovolcano. It is for the firts time that the EPR technique was used to determine the timing of paleofumarole activity and the age of deposits left by paleothermal springs (geyserites) during the EVC history. EPR dating results yielded a much earlier beginning of activity for Elbrus Volcano (mid-Middle Neopleistocene, 220.000 to 200.000 B. P.) and accordingly, a shorter duration compared with the opinion of previous researchers who based their findings on the K-Ar technique and the geomorphic method.

The construction of digital 3D models of volcanoes is now made much easier and faster after the JPL/NASA specialists have carried out an interferometer radar survey of the Earth's surface (SRTM - Shuttle Radar Topographic Mission). Computer processing of the interferometer measurements in the SIR-C/X-SAR wavelength range (L - 23 cm, С - 5.6 cm and X - 3.1 cm) enabled high accuracy to be attained in construction of 3D topographic models, marking more data on these in the geographic coordinate system, and continuing on this basis to develop "digital layers" with data from new eruptions plotted on them, resulting in quantitative estimation of erupted volumes in real time. This method also allows one to model possible locations of new eruptive centers based on fast seismological forecasts of eruptions in addition to predicting possible routes of new lava and pyroclastic flows, mud streams and labors, and assessing the range and geologic effects of an eruption, and its ecologic impact
