On May 30th 2013, there was a UFO sighting at the Popocatepetl volcano, Mexico. The UFO was captured on video approaching at high speed. Then the UFO took u-turn and decended carefully, right into the boiling lava.
In mid August 2013, a UFO sighting was captured on video that was navigating around the Sakurajima volcano, Japan for two days.
Finally, it is worth looking at the meteor crash in Russia on February 15, 2013. Video shows a giant meteor flying through the sky and crashing into a frozen lake. It left a large crater in the ice. Now was this really a meteor? Or have we actually had another UFO sighting here, a close-up in fact?
