HAWAIIAN VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Monday, August 20, 2018, 1:52 PM HST (Monday, August 20, 2018, 23:52 UTC)

KILAUEA VOLCANO (VNUM #332010)

19°25’16” N 155°17’13” W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Kīlauea summit and lower East Rift Zone

Seismicity and ground deformation are negligible at the summit of Kīlauea Volcano. On the volcano’s lower East Rift Zone (LERZ), only a few ocean entries are oozing lava; laze plumes are minimal. Sulfur dioxide emission rates at both the summit and LERZ are drastically reduced; the combined rate is lower than at any time since late 2007.

The Hawaiian Volcano Observatory (HVO) will continue to closely monitor Kīlauea’s seismicity, deformation, and gas emissions for any sign of reactivation, and maintain visual surveillance of the summit and LERZ.

HVO will continue to issue daily updates and additional messages as needed. The next status report will be issued tomorrow morning unless significant changes occur.
