USGS Professional Paper 1750:
A Volcano Rekindled: The Renewed Eruption of Mount St. Helens, 2004-2006
-- Sherrod, D.R., Scott, W.E., and Stauffer, P.H. (editors), 2008.
Mount St. Helens began a dome-building eruption in September 2004 after nearly two decades of quiescence. Dome growth was initially robust, became more sluggish with time, and ceased completely in late January 2008. The volcano has been quiet again since January 2008. Professional Paper 1750 describes the first 1½ years of this eruptive activity, chiefly from September 2004 until December 2005. Its 37 chapters contain contributions of 87 authors from 23 institutions, including the U.S. Geological Survey, Forest Service, many universities, and local and State emergency management agencies. Chapter topics range widely—from seismology, geology, geodesy, gas geochemistry, and petrology to the human endeavor required for managing the public volcanic lands and distributing information during the hectic early days of a renewed eruption.

Q: How big is the new lava dome ???.
The volume of the new lava dome as measured July 5, 2007, was 122 million cubic yards (volume is equivalent to 150 to 200 large sports stadiums) and was growing at an average rate of 0.14 cubic yards per second (nearly equivalent to filling 4 Olympic-sized swimming pools every day.
