Example text

Discharge of thermal waters, at a temperature of up to 88°C, occurs from one of these explosive funnels. All this suggests that the volcano should be considered potentially hazardous. The next eruption is most likely to occur within the same area at the north-western foot of the volcano, and, since it will follow a long period of quiescence, it is likely to be strong. At present it is not possible to make a more accurate prediction of the character, place and parameters of the next eruption. In Kamchatka, there are also other potentially hazardous volcanoes which are at stage II.

However, in this case also the thickness of tephra fall at the site of the proposed construction of the Mutnovskaya geothermal power station will unlikely be more than 3-5 cm (ash load 40-80 kg m- 2 ). It is difficult to make any prediction of future activity for most volcanoes at stage II, especially if their eruptions over the period of the last several 1000 years have been few and 33 irregular. An example of this kind of volcano is Khodutka, which, because of lack of data on its historic eruptions, was not included in the Catalogue of the Active Volcanoes of Kamchatka (Vlodavets and Piip 1959).

On the other hand, the hazard of the volcanism is in general primarily dependent on the physico-chemical status of the magmas, mainly on the temperature and viscosity, the silica content and the amount of gases they contain. How individual eruptions behave, and thus the degree of their hazards and violence, depends on these physico-chemical characteristics, on the tectonic situation at the eruption site, on the amount and rate of flow of magma and on hydrological factors. Together with quantitative knowledge of the volcanic history of the area concerned, these parameters allow the threat of the volcanism to be estimated.
