Guatemalan volcano Fuego increased its activity in recent days in terms of frequency of explosive eruptions. The latest update from INSIVUMEH states that volcanologists registered between 8 and 15 explosions per hour. In previous weeks, a maximum of 12 eruptions were observed. In addition, some explosions are stronger than in previous days. In some cases, so much tephra is ejected that debris avalanches are formed. Incandescent tephra reaches the edge of vegetation and can start fires. VAAC reported volcanic ash at an altitude of 4600 m.
