ELECTRONIC COMMUNICATION AND ENVIRONMENTAL POLICY IN RUSSIA AND ESTONIA*

ABSTRACT. The use of e-mail by a grassroots activist group that straddles the Estonian-Russian border transcends political boundaries and provides ready connections to people in distant places. Activists create a perceived space of resistance in a supportive network that is stretched across space. This network of concern, defined by the physical space in which these activists work and by the strong communicative connections among them, was created to overcome continued environmental mismanagement and remove cultural barriers to cooperation. E-mail communication has enabled an ongoing influence on environmental policy in Estonia and Russia. This circumstance of a collaborative e-mail network created by grassroots activists to aid political work is a testament to how communication technology has expanded for the purpose of strengthening previously silenced voices in a regional and political context.

Correlation of seismic activity and fumarole temperature at the Mt. Merapi volcano (Indonesia) in 2000

In this paper we present densely sampled fumarole temperature data, recorded continuously at a high-temperature fumarole of Mt. Merapi volcano (Indonesia). These temperature time series are correlated with continuous records of rainfall and seismic waveform data collected at the Indonesian–German multi-parameter monitoring network. The correlation analysis of fumarole temperature and precipitation data shows a clear influence of tropical rain events on fumarole temperature. In addition, there is some evidence that rainfall may influence seismicity rates, indicating interaction of meteoric water with the volcanic system. Knowledge about such interactions is important, as lava dome instabilities caused by heavy-precipitation events may result in pyroclastic flows. Apart from the strong external influences on fumarole temperature and seismicity rate, which may conceal smaller signals caused by volcanic degassing processes, the analysis of fumarole temperature and seismic data indicates a statistically significant correlation between a certain type of seismic activity and an increase in fumarole temperature. This certain type of seismic activity consists of a seismic cluster of several high-frequency transients and an ultra-long-period signal (<0.002 Hz), which are best observed using a broadband seismometer deployed at a distance of 600 m from the active lava dome. The corresponding change in fumarole temperature starts a few minutes after the ultra-long-period signal and simultaneously with the high-frequency seismic cluster. The change in fumarole temperature, an increase of 5 °C on average, resembles a smoothed step. Fifty-four occurrences of simultaneous high-frequency seismic cluster, ultra-long period signal and increase of fumarole temperature have been identified in the data set from August 2000 to January 2001. The observed signals appear to correspond to degassing processes in the summit region of Mt. Merapi.
