Reducing risk where tectonic plates collide
Most of the world’s earthquakes, tsunamis, landslides, and volcanic eruptions are caused by the continuous motions of the many tectonic plates that make up the Earth’s outer shell. The most powerful of these natural hazards occur in subduction zones, where two plates collide and one is thrust beneath another. The U.S. Geological Survey’s (USGS) “...Gomberg, Joan S.; Ludwig, Kristin A.
The morphology of transverse aeolian ridges on Mars
A preliminary survey of publicly released high resolution digital terrain models (DTMs) produced by the High Resolution Imaging Science Experiment (HiRISE) camera on Mars Reconnaissance Orbiter identified transverse aeolian ridges (TARs) in 154 DTMs in latitudes from 50°S to 40°N. Consistent with previous surveys, the TARs identified in HiRISE...Geissler, Paul; Wilgus, Justin T.
The lava channel from fissure 8 jumped its banks near Kapoho Crater where the channel makes a 90 degree bend. The flow within the channel was diverted around a constricted area and joined the channel again "downstream" to the south (left).

The dark portion within the red channel is the freed blockage. Lavacontinues to...
Evolution of a blocked channel, photo 1. A blockage of rafted material within the lava channel causes lava to flow over its banks near the Kapoho cone. In this section of the lava channel a cold lava flow from the 1960 eruption forms a barrier on the north side, which initially directed the channel to the southeast. A constriction in the channel formed at the bend where...
