"The Earth Science Picture of the Day (EPOD) highlights the diverse processes and phenomena which shape our planet and our lives. EPOD will collect and archive photos, imagery, graphics, and artwork with short explanatory captions and links exemplifying features within the Earth system. The community is invited to contribute digital imagery, short captions and relevant links."
"The Hawaiian Volcano Observatory (HVO) enjoys a world-wide reputation as a leader in the study of active volcanism. Due to their usually benign natures, Kilauea and Mauna Loa, the most active volcanoes on the Island of Hawai`i, can be studied up close in relative safety. While observations made by 19th-century missionaries and travelers constitute a large part of the early and colorful history of volcano watching in Hawai`i, HVO's origins are rooted in a desire to use scientific methodology to understand the nature of volcanic processes and to reduce their risks to society."
