GPS monitoring of Hawaiian Volcanoes

The USGS Hawaiian Volcano Observatory uses a variety of ground- and satellite-based techniques to monitor Hawai‘i’s active volcanoes.  Here, an HVO scientist sets up a portable GPS receiver to track surface changes during an island-wide survey of Hawai‘i’s volcanoes.

Today we face the third shutdown of the Federal government since mid-November. The lack of an operating budget, now fully four months into the 1996 fiscal year, which began on October 1, has had a crippling effect on the efficient execution of our responsibilities and programs.

The eruption along Kīlauea's East Rift Zone continues with little change from past weeks. The lava is transported underground in a tube from the active vents on the flank of the Pu'u'O'o cone to the ocean at Kamokuna along the eastern side of the active flow field.

Wednesday, January 3, marks the thirteenth anniversary of the start of the nearly continuous eruptive activity at Kīlauea Volcano. The Pu'u 'O'o-Kupaianaha eruption is the longest-lived and most voluminous historic eruption on Kīlauea's East Rift Zone. The thirteen years of the eruption can be divided into three distinct phases.
