The loudest sound in Earth’s history is believed to be the explosion of the volcanic island of Krakatoa, back in 1883. Physicists estimate that the intensity of the sound produced was 1.0×107 W/m2. How many decibels does this correspond to?

Standard reference sound intensity
I₀= 10⁻¹² W/m²
I₁=10⁷W/m²
L=10 log₁₀ (I₁/I₀) =
=10 log₁₀(10⁷/10⁻¹²) =
=190 dB
