Experts say the temperature in Eyjafjallajokull's hole appears to have fallen to 100C, meaning it is now producing steam, not magma（岩浆）.
But officials warned that it was too early to say whether the eruption was over completely.
Ash clouds from the volcano grounded thousands of flights last month.
Steinunn Jakobsdottir, a geophysicist from the Icelandic Meteorological Office, told the BBC that the volcano was "kind of not active for the moment".
"The history of the volcano is such that it calms down and then it gets energy again," she said.
"There are still earthquakes under the volcano, and the small earthquake is still not quite down to what it was before the eruption."
'Difficult to say'
Magnus Gudmundsson, of Iceland University, flew over the volcano on Sunday and said information from heat cameras showed the temperatures at the crater had fallen below 100C.
But he told the AFP news agency that nothing was promised and that the previous eruption at the volcano had lasted 13 months, from 1821-23.
"It stopped and started again several times with different intervals（间隔）, so it's difficult to say, difficult to give a timeline," he said.
He also said it was impossible to say whether the neighbouring Katla volcano - a much larger mountain - might also erupt.
At the height of its activity, the volcano sent out huge clouds of ash, which led to airlines grounding their planes for fear it could interfere with plane engines.
It was the biggest action of closing airspace in Europe since World War II, and affected at least 10 million passengers worldwide.

Chicken feathers are useful, and not just to a chicken. Some go into pillows, coats and other products. But countless chicken feathers go to waste.
In the United States, billions of chickens are produced yearly. Most of their feathers are thrown away.
But instead of being buried in land, some feathers could find a future in plastics（塑料）.
One of the products they have developed is a flowerpot（花盆）. It may look like other flowerpots. But the container breaks down in the earth within one to five years. And as it breaks down, it naturally becomes nutrient（营养物） in the soil.
The environmentally friendly flowerpot is the work of two researchers. Walter Schmidt is with the Agricultural Research Service, part of the United States Agriculture Department. Masud Huda is with the Horticultural Research Institute, a private（私人） organization（组织）.
Walter Schmidt has been working to find uses for chicken feathers since the 1990s. Progress in 2002 showed that plastic made from feathers could be formed like other plastics.
He says feathers are much stronger and last（持续） longer than another plant material. "Feathers are stronger. By design, feathers are also more durable（耐用的）. And the other part about it is if feathers were twice as heavy, or half as strong, then birds couldn't fly."
He points out that traditional flowerpots made from other plastics can last much longer. But he wonders if there is really a need. He says most flowerpots are never re-used.
"Why would you want a plastic that you use for a year to last for two hundred years? It makes no sense. You want to match the product with the use." said Walter Schmidt.
Walter Schmidt and Masud Huda are now adding another chicken product to their flowerpots -- chicken waste. The waste will add more nutrients to the soil as the pot breaks down. The scientists say they hope their flowerpot will be on the market in a year or two.
1.What do people mainly deal with feathers?
A．Feathers are used to make pillows, coats and other products.
B．Most feathers are paid no attention to.
C．Most feathers are used as nutrient
D．Most feathers are used to make flowerpots
2.What’s the advantage of the flowerpots?
A．They won’t last long. B．They can’t break
C．They are environmentally friendly D．They can be reused
3.What does Walter Schmidt think of traditional flowerpots?
A．Too heavy B．Too old
C．Never re-used D．lasting longer but unnecessary
4.What do you think is the main idea of the passage?
A．Chicken and its feathers B．How to deal with feathers
C．feathers made into flowerpot D．New flowerpots

The ISS project is a partnership of five - the US, Russia, Europe, Japan and Canada.
At the moment, no program for its use nor any money has been put in place to support the platform beyond 2015.
One of the biggest issues stopping an agreement on station-life extension（延长期） is the human spaceflight examination ordered by US President Barack Obama.
The Americans are developing a new vision for space exploration, and the rockets and spacecraft they will need to start it. The future of US joining in the ISS is closely tied to the result of the examination.
Mr Dordain, the European Space Agency's (Esa) Director General, said no one partner in the ISS project could alone call an end to the platform. A meeting would be held in Japan later in the year where he hoped the partners could get something clearly going forward. He said it was also necessary the benefits（成效） were increased and the costs were reduced. Increasing the benefits could include finding new uses for the station.
Esa has called for ideas on how to use the ISS as a platform for Earth observation（观测站）. Mr Dordain said the agency had received about 20 very good proposals.
On the issue of reducing costs, there were many ideas on the table, he explained.
He also questioned whether it was necessary for the station to have six astronauts at all times. If there were periods when little maintenance（维修） was required or the experiment load was light, could the ISS run on a smaller group of people, he suggested.
Construction of the space station should finish this year. Next month, two components built in Europe - a connecting node and a robotic control room - will be flown to the platform by the US shuttle Endeavour.
Tranquility and the Cupola, as they are known, will complete the non-Russian side of the ISS.
1.Why will America joining in the ISS be tied to the result of the examination?
A．Because America is the greatest power among them
B．Because America provides most of the money
C．Because they need America’s rockets and spacecraft
D．Because Obama ordered the human spaceflight examination
2.According to Mr Dordain, how should they do to reduce costs?
A．To find new uses for the station
B．To make little maintenance
C．To reduce the experiment load
D．To have fewer astronauts sometimes
3.Where do you think you can read this passage?
A．In a story book B．In a handbook
C．In an advertisement D．In a newspaper

Ben Olsen had great careers as professional players. His story tells a lot about the past, present and future of professional soccer in America.
Ben Olsen was an important part of D.C. United's early success. He was the top new player, or rookie of the year, in 1998. His young professional career reached a high point the next season. D.C. United won the M.L.S. Cup, the league championship（锦标赛）, on the strength（力量） of a Most Valuable Player performance by Olsen. He scored one of two goals for his team in the win against the Los Angeles Galaxy.
Ben Olsen looks back on his score in that championship as his most memorable. "I'd lost a lot of championships before that year, so that was a special game." said Ben Olsen.
Like many top American soccer players, Olsen played overseas. He joined the club Nottingham Forest in Britain. He says different leagues have different styles of play. "Some teams are very fast and athletic. Some teams are a little bit more low pressure on the ball and more skillful players. England has always been known to be a fast and physical league."
Olsen was also a part of the United States World Cup team of 2006. He says playing for his country was something he will never forget.
Ben Olsen has had five operations for severe ankle（脚踝） injuries. Still, he had one of his best years in 2007. He scored seven goals including a "hat trick"-- three in one game.
Ben Olsen celebrates his third goal in one game against the New York Red Bull in June of 2007
He was recognized for his outstanding play with an M.L.S. Best Eleven award. He accepted the award in a wheelchair after a minor operation became major ankle surgery（外科手术）. Ben Olsen retired after the 2009 season. Today he is an assistant coach with D.C. United.
