The tremor which was felt in sections of Jamaica on Tuesday is attributed to final month’s earthquake, based on Professor Simon Mitchell, a Sedimentary Geologist on the Earthquake Unit.
Stories are that the 4.2 earthquake occurred about 1:27 within the afternoon and was situated roughly 10 kilometers South of Hope Bay, Portland.
Mitchell’s evaluation gives useful insights into the geological processes underlying such occasions.
Aftershocks: A protracted phenomenon
Talking on Radio Jamaica’s “Past the Headlines,” Professor Mitchell famous that the affect of aftershocks can reverberate for an prolonged interval, generally spanning as much as a 12 months following a serious earthquake.
Nature’s domino impact: Understanding aftershocks
Professor Mitchell illustrated the mechanics of aftershocks as a fancy interaction of geological forces. He likened the method to a set of dominoes, progressively toppling over.
He defined that when a seismic occasion happens alongside a fault line, it transfers stress to neighboring fault traces. These neighboring faults could reply in numerous methods, generally with speedy actions or remaining dormant till one other minor quake triggers their exercise.
Final month’s earthquake
On October 30, Jamaica skilled a seismic jolt, sending shockwaves throughout the island.
Structural harm was reported in some elements of Portland and Kingston, amongst different parishes.
The final consensus from Jamaicans on social media was that this was the strongest felt earthquake to hit the island in a minimum of twenty years.
In line with studies, the earthquake additionally affected Haiti, the US Minor Outlying Islands, and Cuba.
The epicenter of the quake was 4 kilometers from Hope Bay, Jamaica, with a depth of 10 km.
The earthquake was felt within the Jap and Central parishes of the island, particularly Kingston and St Andrew, Clarendon, St. Mary, St Catherine, St Thomas, Portland, St Elizabeth, and Manchester.
