I would guess that the picture was taken from Ambato, which is the fourth-largest city in Ecuador, 25 km (15 miles) away from Tungurahua. There are some villages closer to it according to the Web site below, and apparently the government has basically had to say "live and let die" to anyone that still wants to live there. The volcano has been threatening for a long time, but hasn't exploded with a deadly eruption yet.
Yep, If you are in that town when the volcano blows, just bend over and kiss it goodbye.
