On June 11, with the support of the federal police, a survey was conducted to recognize the state of the crater of Popocatépetl.

Although the degassing was intense, it could be corroborated that no dome was formed inside the inner crater, which retains its dimensions of 350 m in diameter.

During the last 24 hours, 87 exhalations of water vapor, gas and a little ash were observed. The seismometers recorded 177 minutes of tremor.

After a long period of calm, a minor eruptive activity marks this 13th of June the Voragine of Etna.

Sudden ash emissions occurred through a mouth inside the crater of La Voragine, during the day and continued at sunset ... this type of activity dates back to the summer of 2016.
