2008 eruptions

On 8 November 2008, residents of El Chaco village about 35 km SE of the volcano heard explosion sounds from Reventador. On 9 November, strombolian explosions and 2 lava flows were observed descending the north and south flanks of the central cone.

2002 eruption

Reventador volcano erupted suddenly on 3 November 2002 after 26 years of inactivity. Lava flows descended along the Montana, Marquez and Piedra Fina ravines, destroying roads and highways between Quito and Lago Agrio and damaged local farms.
At 09h12 local time, the main phase of the eruption began, producing an ash column rising to 16-17 km height above the summit. 3-4 hours later, the ash cloud reached the Inter-Andean Valley and the capital Quito ca. 100 km away from the volcano, where it caused almost total darkness in the late afternoon. The ash plume left a layer of fine gray ash up to 3-5 mm thick everywhere.
Over 2 million people were directly affected by the eruption, most of them by ash fall in areas up to 100-200 km distance. Near the volcano, pyroclastic flows devastated the flanks, reaching 8 km from the breached caldera, flowing down steep slopes to reach the Quijos river.
Heavy ashfall occurred in the provinces of Pichincha, Napo and Sucumbios and caused the closing of the international airport of Quito. The Trans Ecuadorian oil pipeline was shut down as precautionary measures.
2 people were seriously injured by impacts of falling tephra. 22 people from surrounding rural areas were evacuated. The Government of Ecuador declared a local emergency and made preparations for the potential evacuation of 3,000 people from the areas closest to the volcano, specifically from the village of El Reventador.
