In the last 24 hours, through the monitoring systems at Popocatépetl volcano, 43 exhalation with emissions of steam and gas, and sometimes slight amounts of ash were detected.

During the night, glow source glases over the crater was observed (image 1).

At this time, we have been observing a light emission of steam and gas which goes forward to the south-southeast direction with no more than 1 km above the crater (image 2).

On march 16, 2018, with support from the Federal Police, an overflight was made to recconoiter the crater of Popocatepetl. It was corroborated that the inner crater remains the same size, about 320 m in diameter and 100 m deep. At its bottom, a small new dome (No 78), of about 50 m in diameter by 30 m thick, and on the walls of the inner crater remains of previous domes could be seen. Gas emmissions could be seen coming from the dome##s surface. It is probable that in the next few days or weeks this dome will continue to grow and eventually it will be destroyed in moderate explosions (video 1).

CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments (image 3) and in case of heavy rains leave the bottoms of ravines by the danger of landslides and debris flows.

The Volcanic Traffic Light Yellow Phase 2.

The scenarios foreseen for this phase are:

1. Explosive activity of low to intermediate level.

2. Ash fall in nearby towns.

3. Possibility of short range pyroclastic flows and mudflows .

Special emphasis is placed on the following recommendations:

1. Continue the safety radius of 12 km, so staying in that area is not allowed.

2. Keep the controlled traffic between Santiago Xalitzintla and San Pedro Nexapa through Paso de Cortés.

3. Civil Protection authorities, keep your preventive procedures, in accordance with their operational plans.

4. People, be alert to the official information disseminated.

In case of ashfall, address the following recommendations:

• Cover nose and mouth with a wet handkerchief or face mask.

• Clean eyes and throat with pure water.

• Avoid contact lenses to reduce eye irritation.

• Close windows or cover them up, and stay indoors as much as possible.

Popocatepetl Volcano monitoring is performed continuously 24 hours a day. Any change in activity will be reported in due course.
