Dear Lukasz, Yes, our figures that are created by personnel working for either the US Geological Survey or the State of Alaska Division of Geological & Geophysical Surveys are available for your use. This information is available on the credit line information for each image. Images created by people from other entities might have additional restrictions. If you modify the figure, the credit line should include that you have modified and who the original creator of the figure was. Thank you, Cheryl Cameron Dear AVO, Greetings from Poland. I work at the Institute of Earth Sciences, the University of Silesia, Sosnowiec, Poland. I'm working on a book and would like to ask how can I legally use some of your images? I would like to describe the Novarupta volcano eruption and see you have some figures that could significantly improve a section related to volcanos. Some of them I would need to modify and translate into Polish. All the best and I hope to hear from you soon, Lukasz
