volcanoes, only five of which are considered to be active (Simkin <I>et al</I>.,
1981): the three stratovolcanoes-Mount Melbourne (in northern Victoria Land),
Mount Berlin (in Marie Byrd Land), and Mount Erebus (on Ross Island; see
Plate G-l)-and the two calderas-Mount Hampton (in Marie Byrd Land) and Deception
Island (near the tip of the Antarctic Peninsula). The volcanoes of Buckle Island
in the Balleny Islands, Penguin Island, Paulet Island, and Lindenberg Island are
also considered to be active on the basis of field studies (Simkin <I>et al</I>.,
1981). Mount Erebus and Deception Island have historically been the most active,
with at least 10 eruptions documented for each</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://geoinfo.amu.edu.pl/wpk/geos/GEO_9/GEO_CHAPTER_9.HTML"><div align="center"><img src="http://content7.clipmarks.com/blog_cache/geoinfo.amu.edu.pl/img/62AD09AE-2D09-4476-86C9-FCE5D188CDE7" alt="Figure 9.15" /></div></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://geoinfo.amu.edu.pl/wpk/geos/GEO_9/GEO_CHAPTER_9.HTML">Landsat image of Mount Takahe, a partially
