Stationary seismic stations.
At present, the network of stationary seismic stations includes stations "Petropavlovsk", "Apacha", "Bering", "Kamenskoe", "Krutoberegovo", "Ossora", "Pauzhetka", "Esso".
All of them but "Kamenskoe" use analog galvanometric channels with recording on photo paper.
-
Strong motion instrument network.
At present, Kamchatkan strong motion instrument network includes 20 stations. Fourteen of these are located along Eastern Coast of Kamchatka and on Bering Island. The instruments are located at stationary seismic stations, lighthouses etc. Six more instruments are located within the territory of Petroparlovsk-Kamchatsky.

Radio-telemetering seismic stations.
The network of automatic, radio-telemetering seismic stations (RTSS) includes three subnetworks with centers at Petropavlovsk (15 stations), Kozyrevsk (4 stations) and Klyuchi (8 stations). The centers perform intermediate data acquisition and accumulation; they are interconnected through hired telephone links.

Continuous GPS observations.
The network of GPS stations is operating at Kamchatka since 1996. At present it includes nine GPS stations for continuous measurement. At each station, a Z-12 type receiver (Ashtech or Topkon) is deployed, with antenna of GEODETIC or ASHDMR type.
-
Electro-telluric observations.
The measurements of telluric current potentials are performed at three locations. The results are transmitted to the Petropavlovsk data center by means of the dedicated telemetry system.
-
Hydrogeodynamical observations.
Hydrogeodynamical observations are carried out synchronously at two piezometric wells. Water level and barometric pressure are measured every 10 minutes.
-
Observatory "Karymshina".
According to the project of international scientific and technological center and the contract with Ministry of emergencies, the Russian-Japanese geophysical observatory - point of complex geophysical observations was created in 1999 near to Petropavlovsk-Kamchatskii. It is aimed at coordinated measurements of electromagnetic and seismic signals. It employs unique sets of instruments provided by Japanese and Russian members of the project.

Hydrogeochemical observations.
Since 1997, the behavior of parameters of underground waters around Petropavlovsk-Kamchatsky is monitored with four hydrogeochemical stations that include, altogether, twelve observation points.
