Modern techniques for interdisciplinary investigation of submarine volcano 6.1 in the Kurile island arc. The paper suggests that there are peripheral magmatic chambers at depth 4,1 - 5,2 km and subvertical conduit channels, submarine volcano, Kurile island arc.

The paper provides results from application of modern computer techniques for interpretation of materials from complex geophysical investigation of submarine Makarov Volcano, the Kurile island arc. Investigations allowed evaluation of rock magmatic properties in-situ, and helped to determine that the most magnetized parts of the edifice are its ridge top and a part of the southern flank up to 2300 m deep. A causative magnetic body traced to the depth of 11,5 km was revealed. The authors suggest that there is a petrified peripheral magmatic chamber at depths from 2,5 to 4,2 km and that a subvertical feeding system of the volcano.

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.
