August 25, 2023 — GPS survey equipment deployed in Kīlauea south caldera
This photo shows one of several temporary GPS survey stations recently deployed in Kīlauea south caldera region. The instruments will record additional measurements during the ongoing heightened unrest. Patterns of earthquakes and ground deformation indicate that Kīlauea's summit is becoming increasingly pressurized. The activity is currently confined within Kīlauea’s summit region and—if it continues—could escalate to an eruption in the coming days, weeks, or months. The activity could also decrease due to intrusion of magma underground, or other changes, resulting in no eruption. USGS phot by A. Ellis.
