Puerto Rico's iconic Arecibo Observatory is under close watch to identify any potential damage during a series of earthquakes. The strongest one was of 6.4 magnitudes on Tuesday. Observatory staff can't check the radio dish or equipments unless the ground stops shaking, and it's still uncertain when it will stop. Since December 28 last year, the area has faced more than 30 earthquakes of magnitude 4 or stronger.
