In Costa Rica, residents of Buenos Aires de Upala reported hearing a noise and observed "smoke-like material" going down the northern slope of the Rincon de la Vieja on May 23, 2017.
A seismic station on the opposite side of the volcano recorded a signal associated with an eruptive episode lasting a minute and a half, with an energy peak at 10:12 on 23.05.2017. Mauricio Gitiérrez, from the Blue River Resort, sent a photo to the Ovsicori where you can observe a few materials descending the slopes
 
On Saturday, May 20th, a phreatic eruption was reported by Blue River staff in Dos Rios de Upala.

In Guatemala, lahars are reported on two volcanoes, the Fuego and the Santiaguito.
Insivumeh reports the descent of weak to moderate lahars at high temperatures, mainly in the Barranca Santa Teresa, composed of fine materials, blocks of 2 meters in diameter, and trunks and branches, and accompanied by columns of steam.
The Santa Teresa barranca, where deposits of pyroclastic flows are present, leads to the river El Mineral, a tributary of the Rio Pantaleon. Nearby villages are requested to take the usual precautions.
 
The Conred reports a lahar descending by the Finca Filadelfia, draining the ashes of the Santiaguito.
