摘要

This study demonstrates the potential of low-cost Raspberry Shake (RS) sensors for advancing volcanic monitoring, using Yasur volcano as a testbed. Deployed at various distances, including directly at the crater rim, these sensors proved resilient and effective in capturing a wide range of eruptive phenomena, from Strombolian explosions to gas puffing events. When combined with thermal imaging, these sensors revealed the spatial and temporal activity of Yasur’s vents. They highlighted the dominant role of S1 in explosive activity and the contrasting behaviors of N1 and S1. By distinguishing impulsive and emergent explosions and tracking continuous gas puffing, the RS sensors offered valuable insights into real-time eruption processes. Additionally, attenuation trends observed at a distance of 2 km emphasized the frequency-dependent nature of volcanic signal propagation and the complementary role of infrasound in remote monitoring. This work not only enriches the monitoring toolkit at Yasur but also demonstrates that Raspberry Shake sensors can be broadly useful for volcanic studies, paving the way for cost-effective, flexible monitoring strategies in challenging and resource-limited volcanic environments worldwide.
