AC/DC’s Melbourne Tour Kickoff Registered on Seismographs Miles From the MCG

Seismologists say ground-mounted speakers with synchronized crowd movement produced low-frequency vibrations detectable across the city.

AC/DC’s first Australian show in a decade produced vibrations strong enough to register on earthquake sensors.

Overview

  • The Seismology Research Centre logged 2–5 hertz ground motion from the Nov. 12 MCG show on a Richmond seismograph several kilometres away.
  • Researchers emphasized the instruments captured ground vibration, not airborne sound, driven by ground‑coupled speakers and coordinated crowd movement.
  • Residents as far as roughly 10 kilometers (about six miles) reported hearing or feeling the concert.
  • The centre said it routinely detects big‑event signals at the MCG, noting Taylor Swift’s 2024 shows generated the strongest concert readings recorded so far.
  • AC/DC’s Australian Power Up leg continues through December with stadium dates in Sydney, Adelaide, Perth and Brisbane, supported by a large‑scale production reported to use about 300 tons of steel and 28 tons of PA.
