On 28 January, with the logistical support of an airplane of the company Alas de Socorro del Ecuador (ADS), a survey was held from the airport of the city of Shell to the Reventador volcano.
During the approach to the Reventador volcano, it was observed that, in clear weather, this one showed pulsatile fumaroles and also small explosions, which emissions have shown a low to moderate content of ash, which are directed to the west. He could be seen scattered deposits of pyroclastic flows through the flanks of the volcano descended not over long distances and are limited only to the foot of the current cone. Currently the volcano emits lava flow from a vent located in the North and aligned in north-south direction from the central crater.
This new lava flow on the north flank of the volcano, has not yet reached the foot of the current cone. The central crater for this flight is characterized by the generation of small explosions. At the foot of the volcano has been observed many ballistic product coming from stronger eruptions (which were not recorded on this visit). In addition, it could be felt a strong odor of sulphurous product, produced in large quantities and dispersed into the environment.
Weather conditions were appropriate for imaging thermal anomalies. The apparent maximum temperature (TMA) correspond to the vent 1 with a value of 501 ° C, followed by the vent 2 with a 372,8ºC value, and North lava flow with a value of 324.6 ° C.

No other significant abnormalities were recorded on the volcano.
