Volcano Watch — The East Rift Zone of Kilauea was a busy place in the 1960s
Volcano Watch is a weekly article and activity update written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates. A fissure on the northwestern crater wall of Makaopuhi Crater on the East Rift Zone of Kīlauea sent lava cascading into the deepest portion of the crater, forming a lava lake. USGS photo taken by E. Endo on March 6, 1965, from a viewing area along the old Chain of Craters Road. While there were several summit eruptions at Kīlauea during the 60s, including one that lasted more than 8 months, eruptions along the ERZ (mainly in the upper and
Volcano Watch — Quantifying corrosion downwind of Kīlauea
Volcano Watch is a weekly article and activity update written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates. This week's article is by scientists from Aotearoa, New Zealand: Carol Stewart (Massey University), Zhengwei Li & Anna de Raadt (BRANZ Ltd), and Graham Leonard (GNS Science). Scientists with USGS and GNS Science install coupons at DESD seismic station, 9 December 2022. Photo by Carol Stewart (Massey University). The purpose was to expand our knowledge base of how metal corrodes in different environments—specifically metal that is often used as building and roofing material. In New Zealand we have carried out
Volcano Watch — ʻAilāʻau or Kualoloa? Hawaiian chants suggest lava flow name change
Volcano Watch is a weekly article and activity update written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates. This week's article is by HVO volunteer and naturalist Bobby Camara, with Pualani Kanakaʻole Kanahele and Donald Swanson. Map showing Kualoloa lava flows originating near the summit of Kīlauea, with pre- and post-Kualoloa lava flows shown for context. District boundaries and ahupuaʻa borders are also shown, along with placenames mentioned in text. The broader northeastern trending part of the Kualoloa flow field contains a number of kīpuka, and a lava delta was built, creating ka lae Kaloli, the prominent point
Volcano Watch — The Art and Science of Geologic Mapping
Volcano Watch is a weekly article and activity update written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates. This week's article is by HVO geologist Drew Downs. Examples of Hawaii geologic maps. The lefthand map is a USGS Hawaiian Volcano Observatory map created on September 17, 2024, within hours of remote sensing (helicopter overflight) of the eruption that occurred from September 15–20, 2024. Several age ranges for lava flows of interest are noted by color changes, with those that erupted from 1790–2018 in purple (older lava flows are gray), those erupted on September 15 in pink, and those
