The eruption is latest after months of activity around Tunguarahua volcano.
An Ecuadorean volcano is spewing ash five miles into the air, closely monitored by experts, after an eruption this weekend.
Ash from the Tunguarahua volcano, whose name means 'Throat of Fire' in the local Quechua language, was blown five miles, 28,000 ft, into the sky and drifted west.
It was the latest eruption from the volcano after a period of calm.
Tunguarahua volcano erupted on 29 July, 4 August and then again on 19 August.
Homes nearby have felt the strength of the eruptions, with the blast causing windows and roofs to vibrate.
Over the weekend the volcano started spewing small pyroclastic flows, a fast-moving current of hot gas and rock which can reach speeds of 450mph and temperatures of about 1,000 C.
