image: Kīlauea lava lake, 2014. The lake surface is spattering in the bright area on the right. This spattering is associated with a source of seismic energy - or 'volcanic tremor' - which is used as a tool to measure tiny changes in the speed that seismic waves travel through the volcano. This material relates to a paper that appeared in the June 28, 2017, issue of Science Advances, published by AAAS. The paper, by C. Donaldson at University of Cambridge in Cambridge, UK, and colleagues was titled, 'Relative seismic velocity variations correlate with deformation at Kīlauea volcano.' view more
