A 4.1-magnitude earthquake that rocked the New South Wales town of Muswellbrook is likely part of an “earthquake swarm” that could see “hundreds to thousands” of small to moderate shocks over the coming months, according to a government seismologist.
The earthquake, which hit around midday on Tuesday and was shallow at 3km deep, is the fourth event over magnitude four in three months in the Hunter region. On 23 August, a 4.7-magnitude earthquake hit Muswellbrook, damaging homes and businesses.
