Earth hums while making 'Love' waves

A subtle and mysterious global hum has been detected by seismologists studying records from earth's most boring seismic stations.
The newfound vibration is made of two-minute to five-minute, side-to-side surface seismic waves, called Love waves.
They are named after the UK mathematician Professor Augustus Edward Hough Love, who created the mathematical model of such waves in 1911.
The discovery comes 10 years after seismologists first identified louder global oscillations that resemble the ringing of a gigantic bell.
