July 31, 11:00 h (July 31, 16:00 GMT)

In the last 24 hours the seismic records of the monitoring system at Popocatepetl volcano registered 24 low-intensity exhalations they were accompanied by gas and steam and five low-intensity explosions which occurred at 17:05, 17:45 and 18:36 h yesterday and at 01:05 and 01:28 h today (image 1) (image 2) (image 3). Additionally, 12 minutes of low-amplitude harmonic tremor were recorded.

Last night we observed incandescence above the crater only with the exhalations (image 4).

At the time of this report we observe the volcano with slight amounts of steam and gas in a westerly direction (image 5).

Other monitoring parameters remain largely unchanged.

CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments (image 6).

This type of activity is included within the scenarios 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.
