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.。

“双十一”深更半夜付尾款早晨就收到货 网友:快递公司是提早埋伏好的吗?******


  每一年双十一都好像一场“全国各地数学课统考”,掏钱至少的人获得胜利,199-25.200-30,店面特惠.天猫红包,不足了还得凑单,結果越凑越大。前三十分钟8折.三十分钟到1钟头9折,网民表明学生时代如果能那么勤奋,早都上清北了。

  殊不知,在这一场欢乐中也有一群局外人,她们不测算立减.不参加预购也不明白标准,每日看见周边的人热闹非凡,自身却在这一场主题活动中一分钱不花,她们被称作双十一编外人员。

  有些人问,为何付尾款总在深夜,是怕大白天大伙儿“世间保持清醒”吗?没有错,深更半夜好像是更非常容易狂野消費,因此一觉起來逐渐为昨日的想法后悔莫及,瘋狂的退款。今日上午“退款人”们也取得成功的把#淘宝崩了送上微博热搜榜。

  可是万万想不到,比退换货更快的是快递,一觉醒来还没有想清晰购买了些哪些,快递早已到。网民也大呼:猜疑快递是提早伏击好的,就等着我付尾款了。

  交了尾款接到快递你觉得就结束了吗?你踏过的较大 招数是分两波付款。11月1-3日是第一波,11月11日为第二波。尾款大家,双十一才刚开局,摸下钱夹,还能再次作战吗?(文/田媛)。


缓解脱发症状,促进新陈代谢,桑葚的功效和作用有哪些?******

原标题:缓解脱发症状,促进新陈代谢,桑葚的功效和作用有哪些?

最近是桑葚盛产的季节,很多朋友都开始蠢蠢欲动,想要到水果市场上去购买桑葚。桑葚对于很多爱美的女性来说,是一种很好的滋养水果,对于保护皮肤功效尤其显著。不过,桑葚可不仅仅只是一种简单的水果,它还具有一些于普罗大众而言十分实用的医学功效与作用。

不少人都经面临过脱发的困扰,尤其是对于那些工作压力极大的人群来说,他们长期面对着电脑,很容易使眼,双眼黯然失色,还会让头发变得干枯毛躁。这个时候不仅需要搭配一些发产品。同时我们还需要通过食疗来进行内部调理。桑葚,就是这样一种很好的天然护发水果,能有效滋养头发。

此外,相信很多人应该都明白“多运动能够促进人体新陈代谢”的道理,但是很多人却由于每天忙于工作和学习而无法运动。这个时候,我们可以考虑食用一些能够帮助促进代谢的水果,可谓是懒人的福利。而桑葚中富含多种维生素,能够很好的加快人体代谢进度,让血管恢复活力。

对于每天都要正常上班的朋友而言,最怕就是晚上遇到睡不着的情况,因为睡眠不足,很有可能会导致第二天工作毫无精神状态,只工作的效率和产出低下。因此有些人为了让自己晚上能够快速入眠,甚至会去服用少量助眠的药物。其实,并不用那么麻烦,桑葚能够在一定程度上帮助大家解决失眠的困扰。

不过,对于桑葚这种水果而言,有一点一定引起注意,那便是在食用桑葚之前一定要进行清洗,因为桑葚的外表会附带很多的灰尘和杂质。最好的办法就是打一盆干净的清水,然后在其中倒入一定量的食盐,搅匀之后再把买好的桑葚放进去,这样就能够彻底将其清洗干净。
