Our Planet lives and breathes. Now some scientists have determined Earth’s vibrational “hum” in other words, the they were able to measure the different frequencies at which our planet naturally vibrates. The new research examined Earth’s permanent free oscillations: low-frequency seismic signals that can only be measured with sensitive instruments. The vibration caused by these … Continue reading Earth’s “hum” captured on ocean floor
