Volcano erupts in Iceland, spurs 50 quakes

Grimsvotn volcano
Reykjavik, Iceland - Iceland's most active volcano erupted Saturday, with a white plume shooting 18,000 feet into the air, scientists said.

The eruption was followed by around 50 small earthquakes, the largest of which measured 3.7 on the Richter Scale, according to Iceland's meteorological office.

There was a similar eruption at the same volcano in 2004.

Scientists don't believe this eruption will lead to air travel chaos like that caused by ash from the Eyjafjallajokul volcano in April 2010.

The Grimsvotn volcano is located underneath the Vatnajokull glacier in southeast Iceland.

Sparsely populated Iceland is one of the world's most volcanically active countries and eruptions are frequent.

They often cause local flooding from melting glacier ice, but rarely cause deaths.

Last year's Eyjafjallajokul eruption left millions of air travelers stranded after winds pushed the ash cloud toward some of the world's busiest airspace and led most northern European countries to ground all planes for five days.

In November, melted glacial ice began pouring from, signaling a possible eruption. That was a false alarm but scientists have been monitoring the volcano closely ever since.

Frequency of Tremors on the Rise in Guerrero

Acapulco,- So far in the month of May, 60 tremors have been registered in Guerrero, mostly in the Richter range of 3 or 4. Monday afternoon a tremor of 4.3 was felt and an earlier one of 5.5 was registered on May 5 with the same epicenter, in the municipality of Ometepec, in the Costa Chica, to the east and south of Acapulco. More than one-third of the tremors taking place in this month in Guerrero have had their origin in the Costa Chica.

Five tremor epicenters have occurred within the municipality of Acapulco since May 1, all of them between 3 and 4 on the Richter scale. The tremors felt in Guerrero in the first two weeks of May is double the number registered for the same period last year.

New Zealand: Aftershocks Continue Daily after Christchurch Earthquake 2011

The Back View of Buildings on High St after Christchurch Earthquake 2011
A series of aftershocks woke a number of Christchurch residents in the early hours of Sunday 15th May, 2011.

Aftershocks continue to rattle Christchurch on a daily basis with 7 occurring between 4pm on the 14th May and 3pm on the 15th May. Some of these shocks relate to the 7.1 September 2010 earthquake and others to the 6.3 February 2011 earthquake.

Aftershocks on the 15th May 2011

According to the Geonet website, Christchurch was shaken by 3 large aftershocks between 1am and 3am on Sunday 15th May. The first was a 4.0 magnitude centered near Springston. This aftershock was close to the area of the September 2010 earthquake. The second and third aftershocks measured 4.6 and 4.0 and both were in the ocean off the East Coast. They were centered just over 20 kilometers from Cathedral Square in Christchurch central.

These aftershocks disturbed many people's sleep and Facebook comments reported that frightened children ran and climbed into bed with parents. Other people described the tremors as a good shake and shudder. One person said their windows rattled and there was also a comment about chairs on wheels moving.

Expert says eruption of Etna volcano linked to earthquake in Spain

Rome - The eruption of the Etna volcano in southern Italy early Thursday is connected to the earthquakes that rocked the Spanish region of Murcia, killing 12 people and injuring more than 170 others, a seismology expert said Thursday.

"We are currently witnessing an intense seismic activity in the entire Mediterranean area from Spain all the way to Malta which has a certain impact on regional volcanoes," said Domenico Patane, director of the Sicily office of Italy s National Geophysics Institute.

Patane said volcanoes are like windows from where underground magma surfaces and it's normal that they respond to earthquakes occurring in a geographic proximity.

"The Spanish eastern coast hit by the quake, after all, lies close to Italy, in the Mediterranean. Both Spain and Sicily are on the same earth plate," he said.

The earthquakes in Spain on Wednesday, which could be felt in Madrid, reportedly had their epicenter near the towns of Lorca and Totana in the Murcia region. The initial tremor of 4.4 magnitude was followed by a quake of about 5.2 magnitude.
