As tectonic plates jostle each other, they stretch and squeeze Earth's crust. Find out where rocks are showing the strain at the World Stress Map Project from the Heidelberg Academy of Sciences and Humanities in Germany. Aimed at everyone from geologists modeling plate movements to engineers assessing earthquake risk, the clearinghouse records nearly 16,000 stress measurements. The values are based on ground slippage from earthquakes, rock fractures during drilling, and other indicators of underground tension and compression. Users can download the database or consult maps that depict the direction of stress and the quality of the data in different places. You can also use the site's software to craft your own maps.
