Mexico's National Center for Disaster Prevention on Wednesday said an eruption at the Popocatépetl volcano caused a 3-magnitude earthquake.

The temblor occurred at 1:11 p.m. Tuesday. The epicenter was in the southeast section of the volcano.

"These earthquakes are part of a swarm or train of volcano tectonic earthquakes that began last Monday," the disaster prevention center, or CENAPRED, said in Wednesday's statement. "At the time of this report there have been counted 366 of these earthquakes."

Popocatépetl is about 43 miles southeast of Mexico City. CENAPRED in March raised the environmental alert level to the second degree out of three, meaning nearby residents should be prepared to evacuate.

A new 4.4-magnitude aftershock with a depth of about 9 km has rattled the region not far from the town of Arquata del Tronto in central Italy, the European Mediterranean Seismological Centre reported. The area suffered a deadly earthquake four days ago. The aftershock's center is located nearly 7 km from Arquata del Tronto. The tremor was felt in Rome, situated more than 150 kilometers south of the town, according to local broadcaster RaiNews24.

A powerful earthquake hit central Italy on Wednesday night, leaving at least 290 people dead with the death toll still rising. A number of small towns and villages were reduced to rubble. Rescue teams dug deep underneath the rubble in the search for possible survivors. Strong tremors were felt in the Italian capital on Wednesday night as well.

As many as 2,500 people have lost their homes to the earthquake, according to the data released by the Italian civil defense authorities. More than 1,800 aftershocks have rocked the region since Wednesday's quake with Saturday night being the first one without any major tremors. Rescue operations are still in progress.

Iceland raised the alarm after its largest volcano was hit by the biggest tremors since 1977.

Two quakes larger than 4 in magnitude early Monday rocked the crater of Katla, the country's Met Office said in a statement. That was followed by at least 10 more tremors at the volcano, which rises 1,450 meters (4,757 feet) into the air on the North Atlantic island's southern coast.

There were no immediate reports of casualties or damages to property.

Earthquake swarm that shook Canadian village still a mystery

McAdam, New Brunswick - 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."

A 3.3 magnitude quake on Feb. 9 shook homes and broke windows. Some people said the tremors sounded like explosions.

"It was a fairly tight cluster, only a few kilometres across, and unfortunately for the people of McAdam it was almost right under the village itself," Halchuk said.
