Buried lasers will sense Earth's spin and quakes doing the twist
The aluminum hatches are the only clue to what lies beneath. Buried amid the corn and wheat fields of Fürstenfeldbruck, a sleepy monastery village 20 kilometers from Munich, Germany, is an inverted pyramid of concrete, steel pipes, and precision sensors, as deep as a three-story building. Last month, when lasers began coursing around the edges of the tetrahedron, Rotational Motions in Seismology (ROMY), as it is called, began its reign as the most sophisticated ring laser in the world, capable of sensing how Earth itself twists and turns.
"It's a structure that has never been built before," says Heiner Igel, a seismologist at Ludwig Maximilian University in Munich and the principal investigator for the €2.5 million machine. "It's something so special." What makes it singular is the finesse needed to keep the lasers stable and to detect tiny changes in their wavelengths.
In doing so, ROMY will measure minuscule changes in Earth's spin rate and spin axis. The speed and pace of those measurements promise to add an increment of precision to GPS navigation, and ROMY may even be able to detect a subtle effect predicted by Albert Einstein's theory of general relativity: the drag of the rotating planet on nearby spacetime, like a spoon turned in a pot of honey. ROMY also will be sensitive to the weak rotations that accompany earthquakes, long-ignored motions that contain clues to the interior structure of Earth. By showing the value of recording those motions, ROMY could pave the way for miniature sensors that could help oil and gas prospectors and even planetary scientists who want to listen for tremors on the moon and Mars...
