Editor's note: iReporters all over the globe are showing us what Occupy Wall Street is like in their towns and cities through the Open Story: from the Aleutian Islands to Raleigh, North Carolina; from Reykjavik, Iceland, to Zadar, Croatia. Check out a map of the reports, videos and pictures here.
The Occupy Wall Street movement, which swept across the United States as thousands demanded that government institutions change to help fix a struggling economy, gained a major boost as the world began to come together in solidarity over shared economic frustrations.
As the sun rose on each country, one-by-one in the same way each stock market would open, protesters took to the streets. What began as a movement that was largely ignored by the mainstream media can't be dismissed anymore, not when thousands of people are sharing rally cries from Zucotti Park in New York to City Hall Square in Copenhagen, Denmark. Perhaps that's what organizers hoped for when they called the global day of protest "Solidarity Saturday."
But that global push may not end with the one day of solidarity. Some would say it has bolstered the ambitions and confidence of those who began Occupy Wall Street. It was a hint that, with the right support and organization, they can spread the message they've so desperately tried to get across: They want change, and they want it now. And even though the frustrations and complaints may differ from country to country, the theme remains that governments aren't handling economic crises properly.
The protests spread amid the growing financial troubles for several Western countries. Maybe that's why it's no surprise the global movement came during a G20 meeting of ministers and bankers in Paris. Finance ministers with the Group of 20 pledged Saturday to take "all necessary actions" to stabilize global markets and ensure that banks are capitalized.
Europeans turned out to protest amid debt troubles and austerity plans in Greece, Belgium, Italy, Spain, Ireland, Portugal and Germany. And in an increasingly intertwined global economy where Americans watch what happens in the Greek debt crisis, the world too is watching to see how the United States is handling its economic issues.
In the spirit of that solidarity, thousands stepped out to support the frustrations of the unemployed in the U.S. and, in some cases, to share their own grievances.
We're taking a look at scenes from across the world to find out more about the main frustrations being lodged and how the protests are drawing support from each other through the lenses of our reporters and iReporters around the world.
The movement gained traction in London especially because of the presence of WikiLeaks founder Julian Assange. Some Brits, who have not been shy to share their frustrations with their economic situation during riots months earlier, echoed American sentiments that governments need to focus not just on the rich but on the little man.
Amedeo d'Amore , an iReporter, was at a demonstration near St. Paul's Cathedral, where he said there were about 1,500 to 2,000 protesters along with a few hundred police officers.
"Essentially, they are very disappointed by the current economic system," he said. "From my understanding, they feel that governments have done too much to protect companies while doing very little to assist the average citizen."
An eruption of Hekla, one of Iceland's most famous volcanoes, may be imminent, scientists in the island nation say.
Pall Einarsson, a geophysics professor at the University of Iceland, told Iceland Review that sensors around the volcano have shown unusual movements in the past few days.
While those sensors are new and the data they provide cannot be seen as conclusive proof that an eruption is coming, Einarsson told Agence-France Presse that "the volcano is ready to erupt."
"The mountain has been slowly expanding in the last few years because of magma buildup," AFP quotes Einarsson as saying.
Volcanic ash: Volcanic ash from an Icelandic eruption is expected to reach London's Heathrow airport - the world's busiest international air travel hub - around lunchtime on Tuesday, Europe's air traffic control organization said.
Concentration of ash is expected to be low and it's not yet clear if Heathrow flights will be canceled.
The ash cloud is forecast to cover all of British airspace by 1 a.m. Wednesday morning, Britain's weather agency, the Met Office, said Tuesday.
Ash will be densest over Scotland, Northern Ireland and northern England, the Met Office said. Heathrow is in the south.
Joplin tornado: As residents in hard-hit Joplin, Missouri, try to recover from one of the deadliest U.S. tornadoes on record, the National Weather Service warns the danger might not be over.
The weather service warns there was a 45% chance of another tornado outbreak – with the peak time between 4 p.m. and midnight Tuesday – over a wide swath, including parts of Texas, Oklahoma, Arkansas, Nebraska and Missouri, including Joplin.
Netanyahu speech:Israeli Prime Minister Benjamin Netanyahu will lay out his vision of a settlement with the Palestinians in a speech to Congress Tuesday morning.
His speech follows an appearance Monday night where he told the main U.S. Jewish lobby that the Israeli-Palestinian conflict persists because the Palestinians "refuse to end it."
In his remarks to the American Israel Public Affairs Committee, Netanyahu said Israel wants peace, "because we know the pain of terror and we know the agony of war."
But, he added, "this conflict has raged for a nearly a century because the Palestinians refuse to end it. They refuse to accept the Jewish state."
He also repeated his argument that Israel's pre-1967 borders were "indefensible."
Iceland hopes its main international airport will reopen to air traffic Monday, following a volcanic eruption in the country on Saturday, a spokeswoman told CNN.
Airspace over the country's four international airports was closed on Sunday.
"There are no international flights in or out of Iceland at this time," Keflavik International Airport spokeswoman Hjordis Gudmunsdottir said.
There was "no impact on European or transatlantic flights" after the Grimsvotn volcano's eruption, Europe's umbrella air traffic control association Eurocontrol said.
Ash is expected to reach Scotland on Tuesday and could enter France and Spain on Thursday, Eurocontrol said.
Last year, another Icelandic eruption, of the volcano Eyjafjallajokull, attracted worldwide attention after its ash cloud disrupted air travel across Europe.
In today's Gotta Watch, we're looking at the awesome power of some of the planet's most active volcanoes. From the easy-to-pronounce Mount St. Helens to another whose name you best not try to utter unless you're sitting down.
Mount St. Helens - On May 18, 1980, Mount St. Helens erupted, becoming the most destructive volcano in United States history. An earthquake and subsequent landslide triggered a series of eruptions and a massive ash cloud. The blast was reportedly so powerful it was felt as far away as Canada. The eruption claimed the lives of 57 people and injured many more.
Eyjafjallajokull - Often refered to simply as "the Icelandic volcano" due to its tongue twister of a name, Eyjafjallajokull wreaked havoc for international travelers for the better part of a week back in 2010. At its peak, the crisis affected 1.2 million passengers a day and 29 percent of all global aviation, according to the International Air Transport Association, becoming the worst disruption of air traffic since the September 11 terrorist attacks back in 2001.
Merapi - The Merapi volcano's most recent eruption began on October 26, 2010. It killed hundreds of people and displaced more than 200,000. The Indonesian volcano's recent eruptions released about 140 million cubic meters of magma, the National Agency for Disaster Management said.
Mount Vesuvius - Just short of 2,000 years ago, the city of Pompeii was wiped off the map by a historic eruption that buried an entire city in ash. Pompeii is now a major tourist attraction and is considered one of Italy's most important archaeological sites.
Iceland's supreme court Thursday ruled in favor of a request by Jinky Young, the alleged daughter of Bobby Fischer, to exhume the chess master's remains, Young's lawyer told CNN.

The eruption of an Icelandic volcano, which had slowed in recent days, strengthened on Monday, spewing a new cloud of ash that officials said was heading toward the United Kingdom - possibly posing a renewed threat to air travel.
The statement came after millions of travelers stranded on both sides of the Atlantic were given a glimpse of hope earlier in the day, with officials announcing a plan to partially reopen European skies to air traffic.
The millions of people stranded by widespread flight shutdowns across Europe had reason for hope Monday as officials announced a plan to partially re-open the skies to air traffic.
What began as a minor inconvenience for travelers stranded by an ash cloud has been multiplied into serious frustration as they try to find ways to combat some serious problems caused by their delays.
By the end of the day on Sunday, a total of 63,000 flights had been canceled in the four days since ash from a volcano under the Eyjafjallajokull glacier in Iceland closed the airspace of a large swath of Europe, according to air traffic authority Eurocontrol.
Paulo Wu is on his fifth day of sleeping in the Amsterdam airport and surviving on airplane food. He says an entire gate is being used to house stranded passengers, and the Red Cross is there passing out “red blankets, greet cots, personal hygiene amenities, and some sandwiches to passengers.”
Volcanic ash from Iceland is snarling air traffic across Europe, causing more than 16,000 flights to be canceled, according to the intergovernmental body that manages European air travel.
The ash cloud originated from an eruption under an Icelandic glacier that began early Wednesday. The eruption under the Eyjafjallajokull glacier - the latest in a series that began on March 20 - blew a hole in the mass of ice and created a cloud of smoke and ash that went high into the air.
And it's causing lots of headaches around the world. Many travelers have been left in limbo - stuck where they are - without any idea of when they may be able to head home, to see loved ones in the hospital or make it to planned events.
Tea Party adherents are using tax day to bring their messages of fiscal responsibility and small government to the streets, raising questions about how to identify a typical Tea Party member, what do they stand for, and how do they come up with some of those crazy signs? Other Americans just want to know where to find tax day deals and freebies.
As ash spewing from an Iceland volcano wreaks havoc on air travel worldwide, images of the natural wonder are captivating the collective consciousness of the Web.
A different kind of natural phenomena is generating a plethora of Youtube clips of the massive fireball lighting up skies over the Midwestern United States. The National Weather Service says a large meteorite could be the cause.
Here’s a look at some of the stories CNN.com reporters are working on Wednesday:
Iceland volcano - CNN has had stories over the last few weeks about the volcano that erupted under the Eyjafjallajokull glacier in Iceland for the first time since 1821. Residents were evacuated while some tourists turned up to watch. But now the huge plume of ash from the volcano is spreading through the skies, closing airspace and bringing travel chaos to northern Europe. CNN will be plotting the airport closures and asking meteorologists where the cloud will affect next as well as seeking pictures of the volcano, which are quite stunning, particularly if you are not affected.
Tax Day: It's April 15 and for many people that means just one thing - got to file those tax returns! CNN will be watching for the expected last-minute rush at tax preparers and post offices.
