Here a compilation of the latest eruptions and seismic unrests around the world.
Kuchinoerabujima volcano, Japan
An explosive eruption occurred at about 9:19 am on January 17, 2019 at Kuchinoerabujima, in the Ryuku volcanic arc in southern Japan.

The strong eruption ejected a plume of ash more than 6,000 meters in the air and produced pyroclastic flows hurtling 1,500 meters down the flancs of the volcano.
Following the eruption, a thick plume of gas and vapor was observed.

Planchón-Peteroa, Argentina – Chile border
Planchón–Peteroa is a complex volcano extending in a north-south direction along the border between Argentina and Chile. On January 15, 2019 at 20h56 local time it exploded sending a greyish ash plume at about 600 meters above the summit.
According to volcanologists, a new eruptive cycle of phreatomatic characteristics develops, following the possible contact of a magmatic body with a part of the hydrothermal system.

This would facilitate the fragmentation of a minor volume of magma and the expansion of steam and the emission of ashes.

For now, it is too fast to speak about the formation of a new volcano.
Ixpaco lagoon is situated at the base of the dormant Tecuamburro volcano, a volcanic depression connected to an underground river, which is greenish-yellow in color BUT can turn white due to the high sulfur content.
