Episode 23 precursory activity at the summit of Kīlauea over the past several days has been characterized by low-level spattering and flames within the vents. The V3cam, recently installed last week, provided shaky views of this activity. On May 22, USGS scientists adjusted the livestream camera to stabilize the view.

Witnessing a volcanic eruption is, for many, a once-in-a-lifetime experience. Hawaiʻi Volcanoes National Park welcomes well over a million visitors from around the world every year, and many of these visitors hope to see lava erupting in person. As enthralling as each eruptive episode is, experts at the USGS Hawaiian Volcano Observatory watch just as closely at what’s happening between episodes.

Episode 22 ended on May 16, after about 10 hours of lava fountaining in Halemaʻumaʻu. Since then, inflationary tilt has continued and another eruptive episode is likely between now and Friday. Geologists conducting UAS monitoring overflights today, May 21, observed a lava pond in the south vent and intermittent spattering from both vents.

As sea levels rise and storms intensify, the threat of coastal flooding in low-lying areas like San Francisco Bay is becoming increasingly urgent. Traditionally engineered levees that hold back water are a first line of defense, but a new study points to a promising hybrid approach: nature-based “horizontal levees”.

Today, the mid-latitudes of Mars are too warm and dry for surface ice to persist; any exposed frost or ice would quickly sublimate into the atmosphere. But a new scientific study, published in JGR: Planets, provides insights into the presence of near-surface ice at several sites in Mars’ northern mid-latitudes—information that could prove critical for future human explorarion.
