Kristi L. Wallace

Kristi Wallace is an observatory scientist focusing on volcanic ash characterization, eruption response, and interagency coordination.

Kristi Wallace is a geologist with the U.S. Geological Survey (USGS)/Alaska Volcano Observatory (AVO) specializing in volcanic ash research and eruption response.  Kristi developed and is the head of the Alaska Tephra Laboratory and Data Center, an interdisciplinary center for studying volcanic ash in Alaska.  Ashfall is a principal hazard from Alaska volcanoes; her work focuses on understanding the frequency, distribution, and character of ashfall in Alaska, specifically from Cook Inlet volcanoes because of their risk to major population centers in Alaska.  Kristi also plays a significant science and outreach role during eruption responses, documenting ashfall events, working with agency partners and the community, and communicating hazards to partners and the public.  In recent years, Kristi has focused on fostering interagency collaborations to help better inform the public about hazards associated with volcanic ash.  She is a founder and US leader of the international IAVCEI Volcanic Ashfall Impacts Working Group focused on ashfall hazard mitigation and a leader in the international tephra-community working group focused on establishing best practice guidelines for tephra studies from collection through analysis to improve data sharing and collaboration among tephra scientists.  Kristi has worked with the USGS in Alaska since 1997.
