Announcement: Subduction Zone Science Workshop – January 10–11, 2023
Subduction zone cartoon showing major parts of a typical subduction zone. Workshop themes align with three USGS subduction zone science and hazard priorities (relevant to earthquakes, volcanoes, landslides, tsunami and cascading phenomena): new observations and models of subduction zone processes, quantification of natural hazards and risk, and forecasting and situational awareness. The meeting agenda includes keynotes, contributed short-format talks and posters (contributions noted on the registration form), and discussions focusing on critical needs, research priorities, and plans for a cross-discipline community of practice. Travel support is available for a limited number of early career participants and for USGS scientists. Reach out to
Photo and Video Chronology — Kīlauea East Rift Zone webcam maintenance and new Kīlauea interferogram
October 23, 2024 — Routine maintenance on Kīlauea East Rift Zone webcam October 23, 2024—InSAR image of Kīlauea middle East Rift Zone deformation This map shows recent deformation at Kīlauea over the timeframe of October 6–18, 2024. Data were acquired by the European Space Agency's Sentinel-1 satellites. Colored fringes denote areas of ground deformation, with more fringes indicating more deformation. Each color cycle represents 2.8 cm (1.1 in) of ground motion. The symbol in the upper left indicates the satellite's orbit direction (arrow) and look direction (bar). The round feature north of Nāpau and Makaopuhi Craters on the middle East Rift Zone
Volcano Watch — Potential long-term outcomes of recent intrusions in Kīlauea East Rift Zone
Volcano Watch is a weekly article and activity update written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates. Chain of Craters within Hawaiʻi Volcanoes National Park before 1969, when several craters were partly or completely filled with lava. Now the Chain of Craters Road turns south, away from its pre-1969 route, between Pauahi and ʻAloʻi, a pit crater buried in 1969 by Maunaulu lava flows. The junction with the Hilina Pali Road is essentially at Devil’s Throat. The eruption in and near Nāpau Crater on September 15–20 is an example of a brief eruption in this area. If
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
