During 30 November-6 December IG reported a high level of seismic activity including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions at Reventador; cloud cover sometimes prevented visual observations. Incandescent blocks were observed rolling as far as 1.6 km down the flanks. Gas, water vapor, and ash plumes were observed on most days rising as high as 1.5 km and drifted SW, W, NW, and NE.
During 9-15 November IG reported a high level of seismic activity including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions at Reventador; cloud cover sometimes prevented visual observations. Almost daily incandescent blocks were observed rolling as far as 1.6 km down the E, SE, and S flanks. Gas, water vapor, and ash plumes rose as high as 2 km and drifted W and NW.

During 3-9 August IG reported a high level of seismic activity including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions at Reventador; cloud cover sometimes prevented visual observations. Incandescent blocks rolled as far as 1 km down the flanks. Gas, water vapor, and ash plumes rose from the crater during 3-4 and 6-7 August; the plumes rose as high as 1 km on 6 August.

On 24 June IG stated that surficial activity at Reventador had remained high during recent months. While conducting routine maintenance work of the monitoring network on 8 June, IG staff noted continuous gas-and-water-vapor emissions rising 800 m above the crater and drifting NW. Explosions produced sounds similar to gunshots and generated ash plumes that rose 2 km.

During 18-24 April IG reported a high level of seismic activity including explosions, volcano-tectonic events, long-period earthquakes, harmonic tremor, and signals indicating emissions at Reventador; cloud cover sometimes prevented visual observations. Incandescent blocks rolled as far as 1.5 km down the flanks on most days. On 18 May a pyroclastic flow traveled 1.5 km down the SE flank, and a gas-and-ash plume rose 1.5 km above the crater.

During 9-15 March IG reported a high level of seismic activity including explosions, volcano-tectonic events, long-period earthquakes, harmonic tremor, and signals indicating emissions at Reventador; cloud cover often prevented visual observations. On 9 March an explosion at 0505 ejected blocks that fell onto the flanks 1.2 km from the crater. An explosion at 0640 produced an ash plume that rose 1 km and drifted NW.
