USGS Long-term change at MLK vent
Used with permission from U.S. Geological Survey.
A time-lapse camera was poised on the southwestern flank of Pu‘u ‘Ō‘ō cone from early 2004 through mid-2007. This location overlooked the “Martin Luther King” (MLK) vent, in the foreground (~70 m away), and provided a distant view of the top of the “Prince Kühiö Kalaniana‘ole” (PKK) tube sys- tem—the Episode 55 lava tube system that carried lava away from Pu‘u ‘Ō‘ō during 2004–2007. This movie shows the long-term development of the MLK and PKK vents by compiling one image per day from April 2004 to October 2006. Some days are missing because of poor visibility or equipment failure. In most cases, images have been rotated, shifted, and (or) cropped to account for unavoidable changes in camera position over the deployment period.
The movie highlights the construction and destruction of spatter cones over the MLK and PKK vents, as well as the growth of rootless shields along the upper PKK tube system. It also shows the rapid rise and fall of the ground surface over the MLK vent area, presumably due to pressure changes within an underlying body of magma.
