The Cenapred reports 64 low-intensity exhalations of gas, water vapor and a little ash dispersing to a western sector, as well as nocturnal glow at Popocatépetl.

The level of alert remains the same, associated with the recommendation not to access the volcano and the crater.

Exploration by E / V Nautilus team of the Lo'ihi seamount continues.
Examination of the hydrothermal activity revealed rocky areas near its summit and the Pele's pit crater covered with a yellow carpet of iron oxide deposits, produced by the active vents or by iron-consuming microbes.
This oceanic environment would be similar to other environments of the solar system, and could perfect the knowledge about the habitability of other planets.
