Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Jessica L Ball, Ph.D.


I am a Mendenhall Postdoctoral fellow at the California Volcano Observatory at Menlo Park, and my work centers on volcanic hazards, particularly those related to volcano hydrothermal systems. I use groundwater and stability models to examine the effects of pore pressurization on edifice instability and collapse. I am also interested in science communication and outreach, and am working with CalVO stakeholders to help write an assessment of volcanic hazard exposure in the state of California. I currently contribute content to the Volcano Science Center websites and social media accounts. I was previously emplyed as the Geological Society of America's Science Policy Fellow and I completed my doctorate at SUNY Buffalo in February 2014, investigating how the stability of silicic lava domes is affected by hydrothermal processes over short and long timescales. Previously, I received my BS in Geology from the College of William & Mary in 2007, and worked from 2007-2008 as the Outreach and Education Assistant at the American Geosciences Institute. My interests also include science communication and outreach, and I currently write the Magma Cum Laude blog for AGU’s Geoblogosphere
