I’m a science journalist in Boulder, Colorado, who specializes in the earth, planetary and astronomical sciences. See below for selected clips, or check out my Twitter feed for more recent news (@alexwitze).

My book ISLAND ON FIRE, coauthored with my husband Jeff Kanipe, is about the extraordinary 18th-century eruption of the Icelandic volcano Laki.
