The ability to fly over the same point several times per day could make it possible to consider in more detail -- and in a more timely manner -- some factors that are currently neglected or underutilized:

* local precipitation[^The potential for nanosatellies in monitoring heavy rainfall in the equatorial band is being explored in recent work, see e.g., [[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6185263 | "Nanosatellites for earth environmental monitoring: The MicroMAS project"]], Blackwell, W. et al. IEEE Xplore DOI 10.1109/MicroRad.2012.6185263 ISBN 978-1-4673-1468-8 in conf. proc of 2012 12th Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment (MicroRad)^][^[[http://en.wikipedia.org/wiki/GPS_Radio_occultation | GPS Radio occultation]] could aid in determining precipitation severity even somewhat beyond equatorial latitudes, since GPS satellites occupy a wide range of orbits.^]
* hydrological changes 
* "slumps" - slow earth movement that might presage faster movement
* herds of animals that could precipitate slides by grazing on unstable slopes[^Detection of herds might be difficult; detection of effects of grazing is, however, already being investigated, see e.g., "[[http://www.earthandspace.org/2010.html | Identifying regional-scale self-organized patchiness in ecosystems using remote-sensing imagery]]", funded by [[http://www.earthandspace.org/ | Earth and Space Foundation]]^]

One of [[Project Persephone]]'s medium-term R&D activities is to support the launch of remote-sensing satellites into [[equatorial low Earth orbit]] (ELEO) for disaster warning, environmental monitoring and emergency communications. ELEO makes it possible to overfly the same point every 90 minutes, which might significantly improve on existing landslide prediction and disaster response in remote areas. Even [[Cubesat]]-size satellites might be able to detect changes in river water color that point to an increased likelihood of mountainside mud flows.[^See, e.g., [[http://strathprints.strath.ac.uk/40010/ | Charybdis: The Next Generation in Ocean Colour and Biogeochemical Remote Sensing]], Christopher Lowe, Malcolm Macdonald, Steve Greenland, David Mckee, presented at Small Satellite Conference 2012^]
