New major explosion at Stromboli volcano, Italy
A new major explosion took place at Stromboli volcano on August 18. An intense explosion at 19:08 UTC involved the mouths of the south-central zone located on the crater terrace, producing a small cloud of ash and the ejection of coarse pyroclastic material, which fell mainly on the crater terrace and on top of the Sciara del Fuoco.
The seismic signal associated with the event lasted a little over 4 minutes. Subsequently, the volcano returned to its normal Strombolian activity.

Nearly 2 million acres on fire in the United States
The West Coast of the United States is shrouded in smoke from the 110 large fires (this does not include smaller fires within each complex of fires) that have erupted across the region during this fire season.
Over 768 900 ha (1.9 million acres) are or have been ablaze. Six new large fires were reported in Idaho, Nevada and Oregon over the weekend and eight large fires have been contained including the Ferguson Fire near Yosemite National Park in California.
This map comes from NOAA and is an experimental model showing both upper level or near-surface smoke. This particular iteration of the map is showing the near-surface smoke (expressed in μg/m3) from the HRRR-Smoke Model. Credit: NOAA
Meteorite from July 27 Arizona fireball found
ASU professor Laurence Garvie, curator of the university’s Center for Meteorite Studies confirmed a stone found in a yard after July 27th Arizona fireball was an 85 grams ordinary chondrite – the 5th witnessed fall meteorite in Arizona. The meteorite was found on August 14 and later sold to a Prescott collector.
Even though the AMS only received 12 reports about this event, the meteorite has been found less than 8 km (5 miles) away from the end of the estimated trajectory computed only based on the witness reports.
Considering the first stone was found in a dense residential neighborhood everyone on this side of Phoenix should be checking their backyards for meteorites, AMS said.
Ice deposits found at the Moon's poles
A team of scientists, led by Shuai Li of the University of Hawaii and Brown University, used data from NASA’s Moon Mineralogy Mapper (M3) instrument aboard the Chandrayaan-1 spacecraft to identify three specific signatures that definitively prove there is water ice at the surface of the Moon.
At the southern pole, most of the ice is concentrated at lunar craters, while the northern pole’s ice is more widely, but sparsely spread.
Most of the newfound water ice lies in the shadows of craters near the poles, where the warmest temperatures never reach above -156 °C (-250 °F). Because of the very small tilt of the Moon’s rotation axis, sunlight never reaches these regions.
Previous observations indirectly found possible signs of surface ice at the lunar south pole, but these could have been explained by other phenomena, such as unusually reflective lunar soil.

Lull in activity at Kilauea volcano continues, sulfur dioxide emissions drastically reduced
The lull in activity at Kīlauea Volcano continues. HVO lowered the Alert Level for ground-based hazards from WARNING to WATCH, on August 17, but the Aviation Color Code remains at Orange. The summit has been quiet since the last collapse event on August 2.
This change indicates that the hazards posed by crater collapse events (at the Kīlauea summit) and lava flows (Lower East Rift Zone; LERZ) are diminished, HVO said.
However, the change does not mean with absolute certainty that the LERZ eruption or summit collapses are over. It remains possible that eruption and collapse activity could resume.
Sulfur dioxide emission rates at both the summit and LERZ are drastically reduced. The combined rate is lower than at any time since late 2007.
The Hawaii Volcanoes National Park has been closed for 102 days, as of August 20, due to unsafe conditions from seismic and explosive activity from the summit of Kilauea and there’s still no decision when the park will fully reopen as the roads are impassable due to sinkholes and cracks, and water lines broken by earthquakes.
