Bromo , Indonesia :
Despite the relatively high level of volcanic activity at Mount Bromo, which is currently emitting thick greyish smoke, sometimes accompanied by ash, the popular destination is reportedly still safe for tourists.
« The small eruption actually offers a more interesting attraction for visitors, to help them understand more about the volcano, » National Disaster Mitigation Agency (BNPB) spokesman Sutopo Purwo Nugroho said as quoted by kompas.com on Wednesday.
However, tourists are warned not to move within a 1-kilometer radius of the crater.
The alert status of Mt Bromo remains at Level 2, indicating caution, which is expected to continue for some time.
« While the volcano’s caution status [remains in place], locals as well as hikers and visitors are not allowed to enter the area within a 1-kilometer radius from Mt. Bromo’s crater, » said Sutopo.

Yasur , Vanuatu :
Elevation 361 m
On 28 June the Vanuatu Geohazards Observatory stated that the Alert Level for Yasur remained at 2 (on a scale of 0-4) and that explosions continued to be intense. VGO reminded residents and tourists that hazardous areas were near and around the volcanic crater, and that volcanic ash and gas could reach areas impacted by trade winds.
The Alert Level for Tanna Volcano remains at Level 2.
This means that the volcanic explosions remains intense, volcanic bombs may fall in and/or around the crater and volcanic gas and ashes can also affect some villages. The area of risk remains around the volcanic crater and in areas expose to trade winds.
This is another reminder to all visitors to observe this volcano away from the crater rim to avoid volcano activity related impacts.
All communities, villages, visitors and travel agencies have to seriously consider this information.
The Department of Meteorology and Geohazards will continue to closely monitor this volcano activity. More information will be provided when necessary.

Santiaguito , Guatemala :
The constant rain in the volcanic area, currently generates a moderate lahar in the riverbed Nima I, with the potential to rise high in the next few minutes, which was recorded by the seismic station Stg3 and reported by the OVSAN.
The characteristics of this lahar are: emanation of a strong smell of sulfur, hot, transport of blocks from 50 cm to one meter, plenty of trunks and branches of trees and pasty volcanic materials.
Because of the intense eruptive activity this year, the accumulation of abundant volcanic material in the region remains the cause of these lahars in the Ángel Cabello River, a tributary of the river Nima I.
These events continue to be generated during the day and especially during the rainy season, we must take precautions, especially at the height of the bridge Castillo Armas on Samalá river.
Therefore, the INSIVUMEH recommends:
Take precautions, because the rain continues and can generate other lahars in the rivers of Santiaguito and Fuego volcano.
At DIRECTION OF ROADS:
Take the precautions they deem necessary, because the rainy season, at the top of volcanos, generate lahars mainly afternoon and evening, with the possibility of flooding and damage to road infrastructure mainly on the bridge Castillo Armas.

Grímsvötn , Iceland :
Elevation 1719 m
On 23 June the Icelandic Meteorological Office (IMO) stated that the water level of the Skaftá river at Sveinstindur (the closest gauging station at 28 km downstream from the ice margin) and electrical conductivity both rose in recent days, indicating the beginning of a glacial outburst flood (jökulhlaup), originating from Grímsvötn’s Western Skaftá ice cauldron.
The western ice cauldron last drained in June 2015. The discharge rate of Skaftá at Sveinstindur was 112 m³/s. IMO warned that hydrogen sulfide released from the floodwater as it drains is particularly potent at the river outlet from the ice margin, where concentrations may reach poisonous levels.
