Physical data have been compiled for eighteen long lava flows, most of which are more than 50 km in length. Flows examined include the Carrizozo and McCartys flows, central New Mexico and the 1907 and 1984 Mauna Loa flows, Hawaii (Earth), flows near Bellona Fossae and Fea Fossae (Venus), flows near Alba Patera and Elysium Mons (Mars), the Phase III Mare Imbrium flow (Moon), and the Amirani flow (Io). Measurements of flow width, flow thickness, and local topographic slope were obtained at regular intervals along each flow. These data reveal several similarities and differences between the flows emplaced in very different environments. All of the longest flows occur on regional plains of shallow slope, generally less than 1 degree. Some flows (e.g. Mauna Loa) are clearly volume-limited while other flows (e.g. Elysium Mons) appear to have components that are cooling-limited. Differences in the gravitational acceleration on the five planetary surfaces do not correlate with flow length, but flow thickness is strongly inversely correlated with gravity except for the two smallest bodies (the Moon and Io). Some flows have relatively small length/width ratios (about 5 for Fea Fossae) while other flows have higher ratios (more than 10 for Mare Imbrium and Alba Patera), or are highly variable along the flow (Carrizozo and Amirani). These data, combined with published rheologic information obtained during emplacement of the 1984 Mauna Loa flow, provide new constraints on likely emplacement conditions for flows on the different surfaces. These new measurements represent the basic input for evaluation of several models of flow emplacement (see abstract #3651 by Peitersen et al.).
