We provide data concerning a weak phreatic eruption of Ekarma Volcano on Ekarma Island, in the Kurils, in June 2010. The ash plumes did not rise higher than 3 km above sea level. A preliminary estimate of the volume of erupted resurgent material (mostly tephra) is on order 2 x 10(5) m(3). Reconstruction of the volcano%26apos;s history and the dynamics of its eruptive activity for the last 4500-5000 years suggests that a larger eruption can occur during the next few decades that will discharge juvenile pyroclastics and/or lava.
