This year's strong earthquakes in Turkey, Taiwan and Southern California were the most monitored in history, but months later scientists are just beginning to understand the data. A record number of instruments on the ground and in space analyzed every quiver of the ground before, during and after the earthquakes, but their measurements do not always agree with each other or with predictions of what should have happened. Dozens of preliminary quake studies were discussed Dec. 15 during the fall meeting of the American Geophysical Union.
