The strong eruptive phase at the volcano has continued during the past several weeks.

The activity is dominated by larger-than-usual vulcanian-type explosions, throwing a large amount of incandescent lava fragments from the summit crater onto the variously oriented slopes. The broad area of the edifice is being constantly brightened by these lapilli-to-bomb-sized tephra fragments as some of the lava bombs, visible in the webcam screenshot, fall outside the frame border, meaning that they reached distances greater than 2 km.

Grey ash-rich columns reached 23,000 ft (7,000 m) height and drifted E.

Seismic records registered 748 minutes of high-frequency tremor, including 1 volcano-tectonic earthquake with magnitude M 1.1 and 155 ongoing emissions of water vapor, gas and ash were recorded over the past 24 hours.

Authorities in Puebla province reported 11 municipalities affected by ashfall.

The crater area of the volcano remains closed for climbing as the risk of being caught in sudden explosions is very high. People are advised to avoid the crater area within a 12 km radius. Additionally, the warning bulletin states that lahars (mud flows) could also occur if heavy rainfalls remobilize fresh ashfall deposits.

The alert status remains unchanged at Yellow.
