Spectacular close-up, nighttime shots of the current lava field flowing from Pu’u O’o crater, Kilauea. Lava channels, pahoehoe lobes, and a sunrise. 2 days ago this lava flow reached the Pacific Ocean - the first ocean entry from the ongoing eruption in several years.

Incredible video of a debris flow captured in the Swiss Alps (I think). Note how the edges and front have built up extra-coarse grained material, a common feature in these sorts of debris flows. Also note that it isn’t raining at this site - this debris flow formed from rocks and water being dislodged farther up slope, so remember that as a hazard warning in mountain valleys.
