Possibility of further volcanic eruptions in Tonga can't be excluded, says expert******

The volcano in Tonga might go quiet after eruption, but the possibility of further explosions can't be excluded, a British expert on volcanoes said Tuesday.。

As rescue teams continued to head to the collection of islands in the Pacific Ocean, Professor Mike Burton from the University of Manchester told Xinhua in an interview that "Because the volcano is basically submarine, we don't know what's going on."

"Almost anything could happen, and we just have to wait and see at this point," said the volcanologist at the university's Department of Earth and Environmental Sciences.。

The eruption on Saturday propelled thousands of tons of ash high into the atmosphere and set off a tsunami. Many of the roughly 170 islands around Tonga are covered with a thick layer of volcanic ash.。

The Tonga volcano, hundreds of kilometers underwater, and around 65 kilometers from Tonga's capital, is something of a mystery, said Burton, who tries to understand when a volcano might erupt by measuring the flux and composition of the often deadly poisonous gases created by volcanic activity.。

"The latest eruption which occurred on January 15 is possibly the biggest eruption we've seen for the last 30 or 40 years. I say possibly, because there are still some question marks over exactly what happened," he said.。

"It appears to be contradictory in some ways. In one sense, there's a sign that this was a very powerful, very big explosion, as it appeared to have gone up very high into the atmosphere, up to about 35 kilometers in height," Burton said.。

"To get that high in the atmosphere, you normally need a huge amount of material to erupt. But instead there's observation suggesting there wasn't that much material that erupted. This comes from both looking at the ash fallout and from the amount of gas released," he added.。

Burton said whether the main eruption is a prelude to another big eruption is yet unknown.。

The impact of the Tonga eruption was felt as far away as in Peru and Japan, and it seems to have damaged Tonga in particular, he said, adding that as the eruption seems to have severed the only communication cable into Tonga, the magnitude of the damage suffered by Tonga is still sketchy.。

Looking to the immediate future, Burton said one of the biggest threats, which isn't immediately obvious, is the risk of a deadly lava flow if there are rainstorms.。

"You can imagine if you get lots of fine ash and coarser ash landing on the ground in depths of meters, and then there's big heavy rainfall, you can get big mud flows which can be very destructive," he warned.。

As for any risk to the wider area of the Pacific Rim, Burton said it might impact ozone concentrations.。

"Because there was obviously a big interaction with seawater, it may be possible there were some unusual chemicals which were injected in great amounts into the stratosphere, things like chlorine and hydrogen chloride. It is one of the gases which can destroy ozone," he said.。

Burton said the risk of a future tsunami hitting China was now unlikely.。

"The impact of the tsunami was within 24 hours or 36 hours of the actual eruption. Now that we're three days past the eruption, the likelihood is there is no more tsunami coming out from the eruption," he said.。

Panama, Peru to play January friendly******

PANAMA CITY, Dec. 3 (Xinhua) -- Panama and Peru will meet in an international friendly next month as both teams prepare to resume their 2022 FIFA World Cup qualifying campaigns.。

The clash will be played on January 16 at Estadio Nacional in Peruvian capital Lima and will have a 4pm kickoff, according to a statement published on the Panamanian football federation's official website on Friday.。

Panama, who are currently fourth in the North, Central America and Caribbean zone (CONCACAF) qualifying standings, will use the match to fine-tune ahead of a triple-header of qualifiers.。

The Central American team will face Costa Rica on January 27, Jamaica on January 30 and Mexico on February 2.。

Peru, fifth in South America's CONMEBOL qualifying tournament, will meet Colombia on January 27 and Ecuador on February 1.。

The top three teams in CONCACAF will earn an automatic World Cup berth while the fourth-ranked side will advance to an intercontinental playoff.。

In the CONMEBOL region, the top four sides will book a direct ticket to football's showpiece event in Qatar and the fifth team will clinch a playoff spot.。

Panama and Peru have not played each other since a friendly in August 2014, when the latter prevailed 3-1 in Lima. Enditem。

Chelsea, Liverpool stroll, while Man Utd crash again in Premier League******

LONDON, Nov. 20 (Xinhua) -- Chelsea remain clear leaders of the Premier League after a convincing win away to Leicester City on Saturday lunchtime.。

Thomas Tuchel's side produced a clinical performance against Leicester and had the game all but wrapped up inside the first half hour thanks to goals from Antonio Rudiger and N'Golo Kante.。

Former Leicester defender Ben Chilwell had already shot against his old team's crossbar before Rudiger headed in his 14th minute corner, and Kante, another former Leicester player, doubled Chelsea's lead in the 28th minute with a powerful left-foot shot.。

Christian Pulisic made it 3-0 on 71 minutes, with the only disappointment for Chelsea being an injury to key midfielder Jorginho, who was replaced with 13 minutes left to play.。

Liverpool remain three points behind in second place after giving Arsenal a reality check and ending the recovery of Mikel Arteta's side with a 4-0 thrashing of Arsenal.。

Jurgen Klopp's men dominated virtually from start to finish, with Sadio Mane opening the scoring in the 37th minute after a cross from Trent Alexander Arnold.。

Diogo Jota scored an excellent individual goal in the 52nd minute as Liverpool upped the pressure and their dominance led to further goals from Mohamed Salah, after good work from Mane, and Minamino who finished the tout in the 77th minute, just moments after coming on as a substitute.。

Things got worse for Manchester United coach Ole Gunnar Solskjaer as his side were beaten 4-1 away to struggling Watford, to give Claudio Ranieri his second win since taking over at Vicarage Road.。

It started to go wrong for Solskjaer before kick-off when Mason Greenwood was ruled out with Covid-19 and they could have been down in the opening minutes only to be saved by David de Gea, who twice blocked Josh King's twice-taken penalty.。

King put Watford ahead from close range in the 28th minute and Sarr doubled Watford's lead on the stroke of halftime.。

Donny Van de Beek pulled a goal back for United in the 50th minute, but Harry Maguire's sending off made things harder for them and Watford completed Solskjaer's misery with two goals in injury time from Pedro and Emmanuel Bonaventura to again put Solskjaer on the brink.。

Steven Gerrard got off to a winning start at Aston Villa as his side won 2-0 at home to Brighton to end a five-game losing streak.。

Ollie Watkins and Tyrone Mings scored the goals in a much-improved Villa performance, although the fans were made to wait with the goals coming in the 84th and 89th minutes.。

Gerrard's predecessor at Villa Park, Dean Smith also got off to a winning start at bottom of the table Norwich as his new side beat Southampton 2-1.。

It was defeat to Southampton a fortnight ago that cost Smith his job at Aston Villa, but goals from Teemu Pukki and Grant Hanley turned the game around for Norwich and gave Smith some revenge after Che Adams had put Southampton ahead.。

Raul Jimenez 56th minute goal decided a tight game between Wolves and West Ham United, who pressed hard after falling behind, but failed to create enough clear chances.。

Burnley and Crystal Palace shared six goals in a topsy-turvy game at Turf Moor, where the lead swapped hands twice before both sides settled for a point. Christian Benteke netted twice for Palace along with Marc Guehi, while Ben Mee, Chris Wood and the impressive Cornet hitting the target for the home team.。

There was no winning start at Newcastle for Eddie Howe, whose side were held to a 3-3 draw by Brentford.。

Howe missed his first game in charge after testing positive for Covid-19 on Friday and it was another chaotic and entertaining affair with Jamaal Lascelles putting Newcastle ahead in the 10th minute, only for Ivan Toney to equalize a minute later.。

Rico Henry then gave Brentford the lead, only for a rare Joelington strike to bring Newcastle level. An own goal from Lascelles then put Brentford back in front, but Allan Saint Maximin saved a point with 15 minutes left to play, although Newcastle are now bottom and remain without a win all season.
