Analysis of Information Availability for Seismic and Volcanic Monitoring Systems: A Review

Area of Science:

• Earth Sciences
• Geophysics
• Volcanology

Background:

• Seismic and volcanic monitoring relies on instrumental networks for data collection.
• Data gaps in acquisition systems hinder early warning systems and scientific understanding.
• Unstable connections and data acquisition delays are primary causes of information loss.

Purpose of the Study:

• To systematically review information availability issues in seismic and volcanic monitoring data acquisition systems.
• To identify and evaluate existing solutions for data gaps and transmission challenges.
• To propose a unified approach for improving data recovery and real-time access.

Main Methods:

• Systematic Literature Review (SLR) using Kitchenham's methodology.
• Extensive search string strategy yielding 1938 articles, refined to 51 relevant publications.
• Content-based filtering focused on seismic-volcanic data acquisition, networks, and early warnings.

Main Results:

• Identified two complementary partial solutions: sequential file identification for continuous data and assessment of alternative transmission media.
• Highlighted the benefit of a unified solution to identify and recover missing data files/plots.
• Demonstrated that recovering data via alternate channels improves real-time information availability.

Conclusions:

• A unified approach is advantageous for addressing information gaps in seismic and volcanic monitoring.
• Integrating file identification with alternate transmission media enhances data recovery efficiency.
• Improved data availability supports more effective early warning systems and research.
