30 cool facts about Mount St. Helens [More info]
Poster commemorating the 30th anniversary of the 1980 eruptions of Mount St. Helens, a volcano in southwestern Washington state. Facts provided in plain text as well.
30 day animations of US daily streamflow maps [More info]
Animated WaterWatch streamflow maps showing daily highs and lows.
PDF A Climate Trend Analysis of Burkina Faso [More info]
Summer rains have remained steady over the past 20 years, but are less than historic highs. Temperature has increased, and while the farmland per person is decreasing, population growth has been offset with improved yields.
PDF A Climate Trend Analysis of Niger [More info]
While summer rains have increased during the past 20 years, temperatures have increased as well, amplifying the effects of droughts. Crop yields are low but the population is growing, pointing to rising food insecurity.
A Magnitude 7.1 Earthquake in the Tacoma Fault Zone-A Plausible Scenario for the Southern Puget Sound Region, Washington [More info]
Scientific description of the likely effects of a significant earthquake on this densely populated area.
PDF A climate trend analysis of Chad [More info]
Long-term reduction in rainfall and increasing temperature threaten Chad's future food production prospects; combined with rapid population growth and zones of substantial conflict, increasing numbers of people will be at risk.
PDF A climate trend analysis of Ethiopia [More info]
Recent trends in March-June, June-September, and March-September rainfall and temperature, identifying significant reductions in rainfall and increases in temperature over time in this area.
PDF A climate trend analysis of Kenya-August 2010 [More info]
Crop areas in west central Kenya are affected by decline in rainfall over several decades; the effects may be exacerbated by overall warming in the region
PDF A climate trend analysis of Mali [More info]
Summer rains have remained steady for the past 20 years, but are below the long-term average. Current population and agricultural trends indicate increasing yields have offset population expansion, keeping per capita cereal production steady.
