William I Rose is professor and has 35 years of experience working in Central and South America and other volcanic countries of the world. He has worked with key hazards mitigation agencies in Guatemala (INSIVUMEH, CONRED), El Salvador (SNET), Nicaragua (INETER) and Ecuador (Instituto Geofisico, Escuela Politecnico) and is familiar with geological hazards in all those countries. He has supervised numerous MS and Ph D projects in these countries. He edited two GSA Special Papers on geological hazards in El Salvador  and in Central America.

Greg Waite is assistant professor with expertise in volcano seismology and geophysics. He has experience in active volcanic systems at calderas and stratovolcanoes.

Wayne D. Pennington s a professor with over 25 years of experience in geophysics and work in developing countries. He has worked on earthquake studies in Pakistan, Mexico, and Colombia, and has survived major earthquakes in two of those countries. He has also supervised several graduate students from developing countries. Most of his current research is involved with the relationships between rock properties and stress/strain, which has applications to the oil and gas industry as well as to hazards. He recently served as an officer for the Society of Exploration Geophysicists, and taught short courses in Bangladesh and Australia.

Stanley J. Vitton is an associate professor with expertise in the area of slope stability analysis and slope stabilization, soil dynamics and foundation engineering. He has eight years of industrial experience in the surface mining industry working in both small scale surface mines in the steep terrain of the Appalachian area of the United States and large scale surface coal mines located in the western United States. He worked on the reclamation of abandoned coal mines and in particular the stabilization of steep slope landslides, where he has conducted research on the stabilization of these slopes for the Office of Surface Mining. He has also conducted research in the area of hazard mitigation by investigating seismic systems for the early detection of tornadoes.
