Geotimes April 2005 Laura Stafford	New Seasonal Hurricane Prediction Scientists are proposing a new method for assessing the probability of a "good" or "bad" hurricane season, which could give insurance companies the ability to plan in advance what sort of protection they may need for their clients.
Geotimes April 2005 Tsegaye Hailu	The Mysteries of Lalibela, Ethiopia The following is a personal geologic travelogue recounting a recent trip to Lalibela, Ethiopia where 11 churches were intricately sculpted out of rock and interconnected by a series of tunnels and trenches..
Geotimes April 2005 Peter A. Scholle	Geologic Etiquette in a Mechanized Era Geologists should exercise more considerate choices regarding the rocks they destroy for science.
Geotimes April 2005 Michael Glantz	What Makes Good Climates Go Bad? Climates are constantly changing in both linear and nonlinear ways and over the course of life on Earth, organisms have either adjusted to those changes or perished.
Geotimes April 2005 Megan Sever	Dream Homes Slip Away The nature of the hillside -- an unstable ancient landslide deposit deep beneath layers of recent fill material -- and the civil engineering of the home sites in Anaheim, California are sparking debate over why these structures cracked and were demolished.
Geotimes April 2005 Naomi Lubick	Sumatra Quake Stronger Than Thought Now that researchers have had time to go back to the records, they are finding indications that last December's Sumatra earthquake released much more energy than they thought, in the form of rare low-frequency seismic waves.
Geotimes April 2005 David B. Williams	Mass Extinction, Massive Problem The great debate continues over the Great Dying -- the largest of all mass extinctions, which occurred 250 million years ago. The latest round of research casts doubt on an extraterrestrial impact as the cause of the extinction event.
Geotimes April 2005 Sara Pratt	Space Dust and Snowball Earth Within the spiral arms of the Milky Way galaxy are thousands of giant clouds of dust. Some researchers now say that these clouds collide with Earth every 140 million years, possibly explaining the causes of two distinct periods of widespread glaciation in the planet's geologic past.
Geotimes April 2005 Megan Sever	Vesuvius' Next Eruption Volcanologists are reconstructing the volcano's past to better predict just what might happen when it blows its top again.
Geotimes April 2005 Sara Pratt	New Dates Defy Fixed Hotspots A new study of two Pacific seamount chains with bends similar to the Hawaii-Emperor chain has found that the bends there formed up to 20 million years apart, challenging the fixed hotspot theory.
