On the morning of February 23, scientists from CENAPRED and the UNAM Institute of Geophysics conducted an overflight of Popocatépetl using a National Guard helicopter. The volcano was clear, with low gas emissions, so the bottom of the crater could be seen. The absence of a fresh lava dome was noted, although remnants of recent small lava domes and small explosion craters were found at the bottom of the crater.
In the past 24 hours, 41 low intensity exhalations have been detected, accompanied by water vapor and gas. In addition, a volcano-tectonic earthquake was recorded today at 08:32, with a calculated magnitude of 1.4.
A slight emission of water vapor and volcanic gases with a northwesterly direction is observed.
CENAPRED urges NOT TO APPROACH the volcano and especially the crater, because of the danger of falling ballistic fragments and, in case of heavy rains, to stay away from the bottom of the ravines because of the danger of mudslides and of rubbish.
The Popocatépetl volcanic alert traffic light is at Amarilla Fase 2.

Volcanic activity on Ambae Island continues at major unrest level. The Volcanic Alert Level remains at Level 2.
The activity of the volcano consists of steam emission and explosions of wet tephra ejected above the surface of the lake but confined in the caldera while only very light ash is deposited on the villages located near the volcano, in especially those exposed to wind directions.
New observations have confirmed that the volcanic cone formed inside Lake Voui and that the Ambae volcano continues to emit volcanic gases and ash contained in Lake Vui.
Ambae volcano activity below Volcanic Alert Level 2 indicating “major level of unrest"; the danger zone remains 2 km around volcanic vents and in the area of flowing streams. With this current volcanic activity, it's a helpful reminder that eruptions can occur at any level of unrest with little or no warning.
All tourist agencies, local authorities, residents of Ambae and the general public are advised that with the current volcanic activity, the danger zone (Danger Zone A) remains at the summit at approximately 2 km radius from the 2017-2018 active vent. Additionally, the presence of remnant volcanic ash elsewhere on the island (deposited during the 2017/18 eruption), may be mobilized by precipitation. Villages near flowing streams (hazardous flow areas) can continually expect changes in stream behavior and higher than normal flows during heavy rains. Residents of Ambae Island should be aware of dangerous water flows when approaching these creeks during

The activity of Fuego / Guatemala is characterized by explosions, at the rate of 3 to 6 weak explosions generated per hour. ; they are accompanied by plumes of gas and ash from 4,500 to 4,700 m. asl. which extend to the west and southwest. The explosions are accompanied by avalanches of weak, moderate and strong characteristics in all the ravines, mainly towards the barranca Ceniza, generating materials that reach the edge of the vegetation.
Weak rumblings and a weak shock wave were recorded, which vibrated the roofs and windows of houses around the volcano. Low sounds similar to those of a train locomotive were heard for periods of 2-3 min.
During the night and early in the morning, an incandescence is observed at a height of 100 meters above the crater and an activity due to an active lava flow 100 meters in length towards the barranca Ceniza.
