Characterization of the June 2019 Eruptions of Raikoke, Kuril Islands and Ulawun, Papua New Guinea Volcanoes

We aim to characterize the June 2019 eruptions of Raikoke and Ulawun volcanoes using remote observations (satellite remote sensing, infrasound, lightning) and to evaluate the state of the art of remote eruption characterization. This is a CIDER 2019 Summer Program: Volcanoes research project. More here.

Strombolian Explosion Seismo-Acoustic Source Dynamics

Here we investigate the volatile budget of a basaltic system, Stromboli Volcano. We deployed a seismo-acoustic network, gravimeter, FTIR, FLIR, and MultiGAS at Stromboli in May 2018. More here.

Ground-coupled Airwave detection and characterization

We developed a minimalist infrasonic signal detection and back-azimuth estimation method using a single seismo-acoustic sensor pair. More here.

Jet noise at Aso volcano, japan

We deployed a 5 element array of microphones on the southern edge of Naka-dake crater of Aso Volcano in July 2015 to investigate the acoustics of a gas jetting fumarole. More information found here

Semblance at sakurajima volcano, japan

In July 2013, we deployed a network of microphones around Sakurajima Volcano and I evaluated how effective the semblance source location technique worked in the presence of significant topographic features. More information found here.

Seismic Auto-correlations at Villarrica volcano, Chile

A seismo-acoustic network was deployed at Villarrica Volcano for much of 2010 and some of 2011. I looked at long term changes in the auto- and cross-correlations of the seismic data to investigate changes in the volcanic edifice. More information found here.
