Short-period volcanic gas precursors to phreatic eruptions: Insights from Poás Volcano, Costa Rica

Monitoring change in volcanic interiors using coda wave interferometry: Application to Arenal Volcano, Costa Rica

[1] Multiply scattered waves are a new tool for monitoring changes in the earth’s subsurface. In this study we use the air pressure and displacement recorded at the Arenal Volcano to detect temporal changes. The pressure pulses emitted by the volcano are associated with a complex displacement signal of overlapping coda waves. By deconvolving the ground motion with the air pressure for different...

Turmoil at Turrialba Volcano (Costa Rica): Degassing and eruptive processes inferred from high‐frequency gas monitoring

Eruptive activity at Turrialba Volcano (Costa Rica) has escalated significantly since 2014, causing airport and school closures in the capital city of San José. Whether or not new magma is involved in the current unrest seems probable but remains a matter of debate as ash deposits are dominated by hydrothermal material. Here we use high-frequency gas monitoring to track the behavior of the volc...

Karaoke in Costa Rica: A Multidimensional Approach to Study Abroad

This case study was conducted to determine the benefits of a multi-dimensional study abroad program that included a community service component. It encompassed the following aspects of the study abroad experience: motivation for travel, language learning research, the role of autonomy in language learning, and cultural awareness, behaviors, and attitudes. The researcher acted as a participant a...
