Skyquakes are defined as unexplained noises heard in the sky.
This is not the first time something odd has been heard over the streets of the city.
What were described at the time as 'loud bangs' were heard in Woodhouse in February this year, while two blasts were also heard in Handsworth, Manor and the city centre in November 2016.
