This image, taken by the crew of Space Shuttle Atlantis (after completing the capture of the Hubble Space Telescope), shows the volcanic plumes from Kilauea rising up from Halemau Crater and along the coastline from lava flows entering the ocean from the East rift zone. The volcanic activity has created a blanket of volcanic fog, called vog that envelops the island. The Hawaii Volcano Observatory (HVO) maintains a website (including webcams) that continuously monitors and updates reports on the volcanic activity. Recent maps indicate expanded lava coverage along the coastal plain. In addition, Hawaii's Department of Health maintains daily vog alerts, and publishes advisories for vog conditions around the "big island" of Hawaii and the state. When this image was acquired, the region west of Hawaii Volcanoes National Park (downwind from the coastal plumes) had a vog advisory for people with respiratory sensitivities. The Volcano Observatory also reported that "Lava from east rift zone vents continues to flow through tubes to the coast and is entering the ocean at two locations west of Kalapana.
