Kīlauea Volcano's summit has been in an eruptive pause since the 2018 events ended over a year ago. Nevertheless, it remains a dynamic place. Ongoing inflation and seismicity indicate that the summit magma chamber is gradually recharging.

Stream stage is still accurately measured by equip under ice, and fluctuates a fair amount due to ice damming and accumulation. Streamflow, however, during most of the winter is typically quite stable.

Sixty years of manned and unmanned space flight have left a cosmic junkyard circling the planet. In 2017, the U.S. government reported that it logged 308,984 close calls with space junk and issued 655 emergency-reportable alerts to satellite operators.

The Shishaldin Volcano on the eastern edge of Alaska's Aleutian Island chain erupted with activity in January of 2020. The eruption on the island of Unimak sent an ash cloud nearly 5 miles into the sky on January 7th, sparking ash alerts for aviators, mariners, and residents of nearby communities.

It's winter in the northern hemisphere, but in Antarctica, summer has just begun. At Zucchelli Station the summer solstice occurred on December 22nd, 2019 at 5:19pm local time. The high temperature that day was a balmy 34 degrees Fahrenheit. These images from Landsat 8 show the distinct difference in sun angles cause by the change in seasons.

Lining up to finish our Snowmobile Safety Training class. Many of the roads we drive trucks on in the summer are inaccessible in the winter, so we must load up a machine.

2018 and 2019 were years of profound change at Kīlauea Volcano and the USGS Hawaiian Volcano Observatory. Devastation caused by the largest lower East Rift Zone eruption and summit collapse in at least 200 years resulted in many transitions for island residents, including HVO.
