Tsunami Warning, Houghton Mifflin/Walter Lorraine Books, 2007 

“Morrison tackles another topic in the science arena with this wide-ranging story of how tsunami warning systems came into being. His well-researched chronological account also looks at the causes and aftermath of these giant waves, as gray-hued illustrations powerfully convey their destructive force.”

—Publishers Weekly

“With paintings more powerful than photographs, the author/illustrator eloquently captures drama and danger of the tsunami. . . . The pictures that show boiling waves, brooding skies and shattered towns will capture younger readers. Older readers will relish the text and come away with a greater appreciation for the scientists who struggle to understand natural disasters in order to keep people safe.”
