Volcano Deformation Monitoring Using GPS
نویسنده
چکیده
Volcanic eruptions are often very destructive events, having a massive impact on the natural and human environment. In order to mitigate the effect of volcanic hazards such as pyroclastic flows, lahars and tsunamis it is necessary to closely monitor volcanoes. Ground surface deformation is recognised as a reliable indicator of an impending eruption and can give clues to magmatic processes at depth. This paper gives a brief overview of the techniques employed for volcano deformation monitoring and then reviews advances in the use of GPS for this purpose. Recommendations on the ideal GPS system infrastructure are made.

Optimizing the Number of Double-Differenced Observations for GPS Networks in Support of Deformation Monitoring Applications
Deformation monitoring using GPS is usually carried out by installing and operating a local network of GPS receivers mounted on the deforming body, e.g. the flanks of a volcano. For continuous monitoring applications a near-realtime, epoch-by-epoch solution obtained from multibaseline processing is desired in order to take into account between-baseline correlations and to detect movements over ...
متن کاملContinuously Operating GPS-Based Volcano Deformation Monitoring in Indonesia: The Technical and Logistical Challenges
In the past decade or so there has been increasing interest in the use of permanent, continuously-operating GPS networks, with a small number of continuous networks having been deployed in the USA, Japan, Canada and Europe for large scale crustal motion studies. However, only in Japan has a country-wide continuous GPS network to support seismic research been established by the Geographical Surv...
متن کاملAllan variance applied to time series baseline results for GPS-based deformation monitoring applications
Deformation monitoring systems seek to detect constant movements with time, varying movements with time or a sudden movement. A slow movement at the millimetre level will not be detected by comparing consecutive session solutions due to inaccuracies between sessions. However, comparisons over several sessions, or days, or weeks, could highlight slow consistent changes. The Allan variance is int...
متن کاملMitigating Differential Troposphere Effects for Gps-based Volcano Monitoring
The UNSW-designed GPS volcano monitoring system installed on Gunung Papandayan seeks to characterise the ground deformation within the volcanic edifice. Hourly baseline solutions produce a time series of data designed to detect any ground motion. Differential tropospheric effects between GPS receivers separated by a large change in height (in this case up to 1400m) impact on the quality of this...
