CHEMICAL AND ISOTOPIC ANOMALIES OF UNDERGROUND WATER-GAS SYSTEMS IN THE PETROPAVLOVSK GEODYNAMIC TEST SITE REGION

Voitov G.I.; Rudakov V.P.; Khatkevich Yu.M.; Ryabinin G.V.; Erokhin V.E.; Bakhur A.E.; Miller Yu.M.; Korobeinik G.S.; Firstov P.P. (2001)
DATA PROCESSING AND STORAGE SYSTEM FOR RECORDS OF WAVE DISTURBANCES IN THE ATMOSPHERE DUE TO VOLCANIC ERUPTIONS

Firstov P.P.; Filippov Yu.A. (1997)

A data processing and storage system for records of wave disturbances in the atmosphere generated by volcanic eruptions is described. The system was developed using acoustic signals recorded during eruptions of Kamchatkan ...
ERUPTIONS AT BEZYMYANNYI IN 1993-1995

Belousov A.B.; Firstov P.P.; Zhdanova E.Y. (1999)

Data on pyroclastic deposits, visual observations, and seismicity were used to reconstruct the sequence of eruptive events at Bezymyannyi in 1993. The eruption consisted of three episodes of block-and-ash pyroclastic flows ...
MONITORING OF SUBSOIL VOLUMETRIC RADON (222RN) ACTIVITY IN THE PARATUNKA GEOTHERMAL SYSTEM IN 1997-1998: IMPLICATIONS FOR USING IT AS A PRECURSOR OF LARGE EARTHQUAKES IN KAMCHATKA

Firstov P.P. (2000)

Monitoring of subsoil volumetric radon activity in the Paratunka geothermal field began in late October 1997. The aim of this work was to find correlation between the Rn behavior and the geodynamic environment in Kamchatka. ...
NONLINEAR OSCILLATIONS IN THE VENT FUNNEL OF THE KLYUCHEVSKIY VOLCANO

Firstov P.P.; Trubnikov B.A. (1988)

During the eruption of the Klyuchevskiy volcano in March-June 1983, acoustic signals associated with explosive action in the Predskazannyy secondary crater and the summit crater were recorded. The activity of the summit ...
THE 1985 ERUPTION OF BEZYMIANNYI

Alidibirov M.A.; Bogoyavlenskaya G.E.; Kirsanov I.T.; Firstov P.P.; Girina O.A.; Belousov A.B.; Zhdanova E.Y.; Malyshev A.I. (1990)

The 1985 eruption of Bezymyannyi has been the largest event since the 1956 catastrophic eruption. A directed blast destroyed part of the volcanic dome and deposited specific pyroclastic material. A series of pyroclastic ...
THE JUNE 1986 ERUPTION OF BEZYMYANNYI

Maksimov A.P.; Firstov P.P.; Girina O.A.; Malyshev A.I. (1992)

This paper presents the results of visual observations, particle-size analysis, seismological observations, and acoustic measurements carried out during a small-magnitude eruption of Bezymyannyi in June 1986. A model is ...
THE NOVEMBER 12, 1964, CATASTROPHIC ERUPTION OF SHIVELUCH, KAMCHATKA: A DYNAMIC RECONSTRUCTION BASED ON SIGNALS RECORDED FROM ATMOSPHERIC PRESSURE VARIATIONS AND VOLCANIC TREMOR

Firstov P.P. (1997)

The microbarographs installed at distances of 45 and 113 km from Shiveluch Volcano recorded acoustic signals during the powerful explosive eruption of November 12, 1964. The signals were produced by the formation of a ...
THE SEPTEMBER 7 - OCTOBER 2, 1994 ERUPTION OF KLYUCHEVSKOI VOLCANO, KAMCHATKA

Ozerov A.Yu.; Karpov G.A.; Droznin V.A.; Dvigalo V.N.; Demyanchuk Yu.V.; Ivanov V.V.; Belousov A.B.; Firstov P.P.; Gavrilov V.A.; Yashchuk V.V.; Okrugina A.M. (1997)

An extrusive-explosive, mainly Strombolian eruption occurred in the crater of Klyuchevskoi Volcano on September 7 - October 2, 1994. The eruption grew more violent and changed to a kind of subplinian activity during the ...
