Cause of earthquakes that shook a New Brunswick village for months is a mystery
MCADAM, N.B. — The cause of more than 100 earthquakes that shook homes and rattled nerves in a New Brunswick village earlier this year may remain a mystery, says a seismologist.
Stephen Halchuk at Earthquakes Canada said the kind of earthquake swarm that began rumbling under the village of McAdam in February is unusual but not unheard of.
“There have been other swarms of activity in eastern North America. There have been ones in Maine and in Connecticut and some further to the west as well,” he said.
“It still remains a mystery as to why this particular area is generating them. It just appears to be a zone of weakness in the earth’s crust. There’s not a well defined fault that we can point to and say that’s what’s causing it.”
