00:06:44	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.
