Video of Volcan de Colima from an unmanned aerial system

A video of Volcán de Colima's summit dome (approx. elevation 3870 m) was taken
during a test flight by a tactical Ehécatl S4 aerial surveillance system. This
is one of the operational unmanned aerial systems (UAS) developed by the
Mexican company Hydra Technologies for civil protection surveillance, public
safety, ecology, among other purposes. Some of these systems have been acquired
by other countries, and the company claims that their operational costs are
lower than their competitors. The neighbouring inactive peak of Nevado de
Colima (4260 m elevation) is also visible in the video.
Volcán de Colima has been undergoing an episode of lava dome growth since early
2007 at an extremely low extrusion rate. Minor explosive activity has also been
registered. A new lava lobe was first observed on 20 February 2010 on the W
flank of the dome, which is continuing to cause occasional rockfalls.
