Steve Mattox worked on VolcanoWorld until July of 1996. He has moved to Australia-we wish him well. As part of his post-doc position at University of North Dakota he developed educational projects that utilize VolcanoWorld. His background is in both research and education. He completed his Ph.D. in 1992 at Northern Illinois University where he studied how tectonics, source, and processes influenced the composition of Cenozoic rocks in the Marysvale volcanic field, Utah.

As a volunteer, Steve assisted U.S. Geological Survey geologists monitor the on-going eruption of Kilauea. He worked three seasons at Hawaii Volcanoes National Park as an interpretive ranger and wrote A Teacher Guide to the Geology of Hawaii Volcanoes National Park, a 391-page curriculum for K-12 students. He is CO-PI of Volcanology for Earth Science Teachers, a NSF-funded program that brings teachers from states with active volcanoes to Hawaii for extensive training. He has taught geology classes at Northern Illinois University, School of the Art Institute of Chicago, and University of Hawaii at Hilo. In addition to training teachers at state, district, and local levels in Hawaii, Steve volunteered at an elementary school to teach fourth graders about the numerous nearby geologic hazards.

Steve was responsible for the day to day operation of VolcanoWorld and developed a majority of the descriptions of volcanic activity, regions, and processes.

Steve wishes to thank:

• I thank Chuck Wood for the opportunity to tell students and the public a little bit about volcanoes.
• The VW computer team, headed by Prabhu "no problem" Ram, makes us look good. Ken, Kelly, Kelly, Dave, and Jeremy did great work and it only cost me one calendar! Jamie Dronen and Dave Carlson kept the machines in the Department of Spaces Studies working.
• Matt Axwig made working in the dark interior of the computer room much brighter.
• I thank Brad, Jim, and Jon for opening my eyes to new ways to educate people about volcanoes.
• Thanks to Scott Rowland for his additions to VolcanoWorld, answering hundreds of Ask a Volcanologists questions, and making me laugh.
• Jane Takahashi allowed me to copy slides from the photo archive of the U.S. Geological Survey's Hawaiian Volcano Observatory. The photographs of Jim Griggs, former HVO staff photographer, have been exceptionally useful. The U.S. Geological Survey slides greatly contributed to the pages about Hawaii and the park.
• The following individuals generously shared photos: Jack Lockwood, Steve O'Meara, Donna Donovan O'Meara, Tari Mattox, Rick Moscati, Dick Van Effen, Forest Hopson, Carl Thornber, Dana Harper, Rosemary Kenney and Beverly Voight, Michael Lyvers, David Mitchell, Paul Buklarewicz, Christina Heliker, Wendell Duffield, George Ulrich, Jim Walker, Brittain Hill, and W. Kenneth Hamblin.
• The photographs of Steve O'Meara greatly enhanced the beauty and content of VolcanoWorld.
• E-mail from Tari, Rick, Rich, Paul, Bobby and Julie made me laugh and kept me warm on cold North Dakota nights.
