Fire Danger Expected Number of Fires per PSA
This map takes into account both probability of ignition and conditional probability of spread (to 500+ acres in East and 1000+ acres in West*) given ignition.
Fire Potential Index (FPI) forecast
The FPI is most similar to the Energy Release Component of the National Fire Danger Rating System in that both are moisture related indexes and neither indicates the effect of wind on fire potential.

How do lava flows cool and how long does it take?
This ‘a‘ā flow erupted from fissure 8 on Kīlauea Volcano's lower East Rift Zone on June 1, 2018, shows how the interior of a lava flow remains incandescently hot even though surface cooling forms a crust of solid rubble.

Low sulfur emissions mean a new focus on a different volcanic gas
Low sulfur emissions mean a new focus on a different volcanic gasA USGS pilot and Hawaiian Volcano Observatory gas geochemist prepare to conduct a test flight of an unmanned aerial system (UAS) on Kīlauea Volcano in November 2018. This UAS was outfitted with a prototype miniaturized multi-gas sensor for the detection of volcanic gases emitted by Kīlauea, including sulfur dioxide and carbon dioxide.

50,000 tons of sulfur dioxide gas per day
In mid-July 2018, fissure 8 (shown here) on Kīlauea Volcano's lower East Rift Zone was emitting more than 50,000 tons of sulfur dioxide gas per day, creating high levels of vog on the island. Since early August, lower East Rift Zone SO2 emissions have dropped to less than 100 tons per day, resulting in better air quality for Hawaii.

Impact of Hurricane Lane on Wailuku River
Two views from the Rainbow Falls overlook, downstream of the Wailuku River streamgage near Hilo, Hawaii. The image on the left shows a typical base flow of about 35 cubic feet per second (cfs). The image on the right shows the early impact of Hurricane Lane with a flow of about 26,000 cfs taken at 8:35 a.m. HST, August 23, 2018. This U.S.

Why do some Hawaii earthquakes occur so far offshore?
Why do some Hawaii earthquakes occur so far offshore?Many of the earthquakes in Hawaii that extend offshore and up the island chain are due to plate bending, or flexure. The upper panel shows magnitude-5 and greater earthquakes since 1861, with some notable events labeled.
