Around 18:00 in the afternoon of April 7, the seismic energy values showed a significant drop which remained at an average of 48 RSAM units these days. In the last 24 hours the seismic vibrations of the Chaparrastique volcano fluctuated between 31 and 38 units RSAM / hour on average, with an average of 34 units, the maximum threshold of normal behavior is 150 RSAM units on average (Figure 1).
The weather images captured by the webcam installed on the hill El Pacayal show cloud cover that prevents to observe the crater.
Data show that the internal system of volcano is during the rebound phase. However, the behavior of volcanic activity that showed the Chaparrastique indicates that these relaxation periods are usually followed by drastic changes that sometimes ended up by weak ash emissions or periods of strong degassing, this being the behavior typical of an active volcano.
MARN continues to monitor, maintain close communication with the General Directorate of Civil Protection and local observers.
