20160425 Standard_(Ecuador quake) Time runs out for survivors; deaths rise to 587

The death count from Ecuador's worst earthquake in a decade increased to at least 587 on Thursday even as the country faced another grim toll: a long and costly reconstruction effort likely to cost billions of dollars.
On Thursday evening, the government raised the death toll to 587. 
Officials listed 155 people as missing and the number of those made homeless climbed to over 23,500. The final death toll could surpass casualties from earthquakes in Chile and Peru in the past decade.
President Rafael Correa announced Wednesday night that he would raise sales taxes and put a one-time levy on millionaires to help pay for reconstruction.
The damage from the 7.8-magnitude quake adds to already heavy economic hardships being felt in this OPEC nation because of the collapse in world oil prices. Even before the quake, Ecuador was bracing for a bout of austerity, with the International Monetary Fund forecasting the economy would shrink 4.5 percent this year.
In a televised address Wednesday night, Correa warned the nation of a long and costly post-quake recovery and said the economic pain shouldn't fall only on hard-hit communities along the coast.
“I know we're at the most-difficult stage right now but it's just the beginning,'' he said.
Rescuers continued to comb through the rubble in coastal towns hit hardest by the quake, but the clock was running down for finding survivors. Rescue workers have said a person without serious injuries can survive up to a week buried in debris in the Ecuadorian heat.
On Thursday, Jorge Zambrano, mayor of the community of Manta, announced that three people had been pulled from beneath a collapsed building the night before and vowed to continue searching.
“I still have hope we can find more people who are still alive beneath the rubble,'' he said. “If we have even a hope of life, we must work with extreme care.''
Rescuers also found a more unusual survivor: a flapping white-and-brown duck was pulled from under a pile of rubble, becoming a social media celebrity in a country eager for good news.
Using authority granted by the state of emergency he declared after Saturday night's quake, Correa said sales taxes would increase from 12 percent to 14 percent for the coming year.
People with more than US$1 million in assets will be charged a one-time tax of 0.9 percent on their wealth, while workers earning over US$1,000 a month will be forced to contribute a day's wages and those earning US$5,000 a month the equivalent of five days' pay.
Taxes on companies will also go up, and Correa said he will look to sell certain state assets that he didn't specify. He is also drawing on US$600 million in emergency credits from the World Bank and other multilateral lenders.
The tax increases come as the scale of devastation continues to sink in. A helicopter flyover of the damage zone Wednesday showed entire city blocks in ruins as if they had been bombed.—AP

20160418 BBC_Japan earthquake: 'Nearly 250,000 told to leave amid fear of tremors'


http://www.bbc.com/news/world-asia-36069405

Saturday's magnitude-7.3 quake struck at 01:25 (15:25 GMT on Friday) close to the city of Kumamoto, which had been hit by a magnitude-6.4 quake on Thursday night.
Both quakes were shallow, causing huge damage to roads, bridges and tunnels. Big landslides cut off remote mountain villages.
The US military said it was preparing to provide aerial support for Japan's relief efforts. America has several military bases and about 50,000 troops in the country.

The earthquakes are the biggest to have hit Japan since 2011 when a 9.0 magnitude quake caused a huge tsunami, leaving more then 19,000 dead and missing.
Japan is regularly hit by earthquakes but strict building codes mean they usually cause minimal damage.

A state of emergency has been declared and some 10,000 troops and 3,500 police have been deployed in the affected areas, with an emphasis on finding survivors.

"I fear that figure will go up because we keep on removing rubble," a shaken Mr Correa said in a televised address.
"There are signs of life in the rubble, and that is being prioritised."
The magnitude-7.8 quake struck on Saturday evening. Coastal areas in the north-west were closest to the epicentre.
The quake is Ecuador's largest since 1979. More than 130 aftershocks have followed.
The US Geological Survey said the earthquake struck at a fairly shallow depth of 19.2km (11.9 miles), about 27km from Muisne in a sparsely populated area.
The quake was also felt in neighbouring Colombia.

20150918 Ming Pao【智利8級強震】百萬人疏散 海嘯預警遠至日本新西蘭 (14:51)

智利海岸發生8.3級強烈地震,已造成5人死亡、1人失蹤,100萬人疏散。地震後當局發出海嘯警報,部分沿海地區被淹,遠至亞洲日本都在預警範圍內。
智利總統巴切萊特說,死者包括遭屋頂塌下砸死的35歲女子、被落石壓死的20歲女子,以及心臟病發死亡的80多歲老翁。她計劃前往受影響最嚴重的災區。這是智利2010年以來最嚴重的地震。
路透社引述海軍稱,已經有4.5米高海嘯湧向海濱城市科金博。智利政府敦促居民撤離海岸線。
智利外海發生8.3級強震後,不僅美國加州部分地區發布海嘯警示,地震威力大到連距智利9600公里的新西蘭,也警告民眾小心新西蘭部分地區可能出現海嘯。
路透社報道,美國國家海嘯警報(National Tsunami Warning Center)中心向加州部分地區發出海嘯警示,並表示抵達加州部分地區的海浪預計高度將不到0.3米。
美聯社報道,太平洋海嘯警報中心(Pacific Tsunami Warning Center)表示,南太平洋最可能受到波及的地方是法屬玻里尼西亞,可能出現3米高海浪。
新西蘭民防部17日發布海嘯預警說,智利強烈地震引發的海嘯可能波及新西蘭,提醒新西蘭南北兩島東部居民遠離沿海地區,又說如果海嘯真的來襲,可能將在當地時間18日凌晨出現(香港時間17日晚間8時)。
民防部在聲明中表示,智利地震後,新西蘭南北兩島東部可能會出現較大海浪,對河口、海岸、港口等區域影響較大。聲明說,現階段地質評估顯示,新西蘭沿海地區出現海水倒灌可能性不大,但相關情況可能隨時發生變化。
聲明說,預期海嘯將在智利地震後12小時抵達新西蘭東部外島查塔姆群島,13小時後抵達新西蘭北島最東端。強大的海浪預計在新西蘭東部海域持續24小時,最高峰可能維持4至10小時。
民防部表示,部分東部地區的居民應該遠離海灘與海岸線。這些地區包括東角(East Cape)、查塔姆群島(Chatham Islands)、科羅曼德(Coromandel)與班克斯半島(Banks Peninsula)。

20150917 BBC_Chile quake triggers mass evacuation and tsunami alert

One million people had to leave their homes in Chile after a powerful quake hit the country's central region.
At least eight people died when the 8.3-magnitude quake hit. One person is still missing.
Residents of Illapel, near the quake's epicentre, fled into the streets in terror as their homes began to sway.
In the coastal town of Coquimbo, waves of 4.7m (15ft) hit the shore. A tsunami alert was issued for the entire Chilean coast but has since been lifted.
Tsunami waves also hit the coast further north and south of the quake's epicentre, with waves half a metre higher than usual as far north as La Punta.

The quake lasted for more than three minutes and there have been dozens of aftershocks.
Gloria Navarro, who lives in the coastal town of La Serena, said people were "running in all directions".

At the scene: Jane Chambers, freelance journalist

I'm on the coast about 130km (80 miles) south from the worst affected area of Coquimbo. Our house is on top of a cliff and made of wood. It was shaking and shuddering.
At first I thought it was just a tremor but it was really strong and went on for around three minutes. It was much stronger than any tremors I had ever felt before.
The house is fine as most of Chile's buildings are built to withstand tremors.
The local town was evacuated. The restaurant down on the beach is flooded but most things here are returning to normal.

Officials said 1,800 people in Illapel were left without drinking water.
Electricity providers said hundreds of thousands of their clients in the worst-affected Coquimbo region had no power.

The US Geological Survey (USGS) said the tremor struck off the coast of Coquimbo, 46km (29 miles) west of the city of Illapel at 19:54 local time (22:54 GMT).
The USGS said it was at a depth of 25km, while Chilean seismologists calculated its depth at 11km.

The quake that rocked Chile on Wednesday was five times more energetic than the one that devastated Nepal back in April. And yet the early indications are that the death toll will be a fraction (perhaps a thousandth) of what it was in the Himalayan nation.
In large part, this is simply down to preparedness. This was Chile's third massive quake in five years; the region all too frequently experiences magnitude 8 events. As a consequence, the building codes are strict and generally well enforced.
What is more, the people themselves are well versed in how to react during and after an event.
It is not perfect. In 2010, an 8.8-magnitude quake witnessed failings on the part of the monitoring network and the system for alerting people to the imminent tsunami threat.
Since then, the Chilean government has spent millions upgrading the country's seismic network of sensors, and made improvements to telecommunications systems that share critical information and warnings.

The earthquake struck as thousands of Chileans were travelling to the coast ahead of a week of celebrations for independence day.
President Michelle Bachelet said some of the official festivities would be cancelled.
The authorities were quick to issue tsunami alerts keen to avert a repeat of the slow response to the 8.8-magnitude quake in 2010, which devastated large areas of the country.
More than 500 people died in that quake and the tsunami it triggered and memories of the tragedy are still raw.

Image captionAs day broke, residents began to take stock of the damage

Tsunami alerts were issued shortly after the quake struck for the entire Chilean coast but have been gradually lifted, with the last cancelled at 06:22 local time.
President Bachelet said that "once again we must confront a powerful blow from nature". She will travel to the affected areas later on Thursday.
Chile is one of the most seismically active locations on the globe.
It runs along the boundary between the Nazca and South American tectonic plates. These are vast slabs of the Earth's surface that grind past each other at a rate of up to 80mm per year.

20150917 China Daily_Powerful quake hits off coast of Chile, coastal evacuations ordered

SANTIAGO, Chile - A magnitude 8.3 earthquake hit off the coast of Chile on Wednesday, shaking buildings in the capital city of Santiago and generating a tsunami warning for Chile and Peru.
Chile's government urged residents to evacuate the coastline. There were no immediate reports of injuries or damage.
Reuters witnesses said the quake was felt as far away as the Argentine capital, Buenos Aires, on the eastern seaboard of South America.
The quake struck 105 miles (169 km) north of Valparaiso and was originally reported as magnitude 7.9, the US Geological Survey said.
Hazardous tsunami waves from the quake were possible along the coasts of Chile and Peru within the next several hours, the Pacific Tsunami Warning Center said. A tsunami watch was also issued for Hawaii.
If tsunami waves impact Hawaii, the estimated earliest arrival time would be 3:06 a.m. Hawaii Standard Time (1306 GMT) on Thursday, the Pacific Tsunami Warning Center said.
The quake struck at a depth of 15.5 miles (25 km), the USGS said.
Less than an hour after the initial earthquake, three aftershocks all greater than magnitudes 6.1 struck the region, USGS reported.
Chile's state copper miner Codelco said workers at its Ventanas division have been evacuated.

There is little danger of being late for lunch in Montserrat.
At 12:00 sharp every day, the mournful wail of the tiny island's volcano sirens cut through the air like a knife.
The ominous soundtrack to life in this British overseas territory can be heard across inhabited parts of its 100 sq km (39 sq miles).
Residents know if the sirens blare at any moment but noon, it's time to run - fast.

Taunting in its perpetuity is the steam and bluish haze of sulphur dioxide emitted from the slumbering monster in the south, whose constant threat pervades the atmosphere like a viscous liquid.

Incessant activity

This is the reality for those living in the shadow of Soufriere Hills.

Map of Montserrat

Last month, Montserratians marked 20 years since the start of the volcanic crisis which has rendered two-thirds of the island an exclusion zone, turned the capital city into an apocalyptic movie scene deep in ash and changed life here forever.

Few imagined when a vent in the volcano - dormant for several hundred years - began smoking on 18 July 1995 that it would awaken with such a vengeance.
Or that its incessant activity, rather than the sudden brief explosions favoured by Hollywood, would continue to this day.
Back in the early 90s, Montserrat's future looked bright.
A mammoth cleanup after devastating Hurricane Hugo in 1989 had seen the construction of much modern infrastructure and the territory was experiencing unprecedented prosperity.
There was even talk of independence from Britain.

Fiery spectacle

When the hills first started to emit their brilliant white steam, islanders say it was mesmerising and exciting. People would gather in the evenings to watch the fiery incandescence in awe.
It was 14 months before the first eruption took place in September 1996, sweeping away the villages of St Patrick's and Morris in less than 20 minutes.

That year, the capital Plymouth was evacuated for the final time - abandoned to become slowly buried under repeated mudflows - and a state of emergency declared.
Today, Soufriere remains one of the most active volcanoes in the world.
The population has plummeted from 11,500 to 5,000 with the south of the island divided into five zones.
Permission to access them is dependent on the current hazard level.

Strong bonds

Over the years, businesses have rebuilt in the north, municipal offices have relocated to Brades and the government has created new housing at Lookout, Davy Hill, Shinlands, Drummonds and Sweeneys.

Despite the gases and ash falls - which occasionally reach as far as Antigua - Montserrat's stoic inhabitants largely go about their business unperturbed, refusing to be defined as living on the precipice of peril.
Tourists are politely told that "Montserrat is not a volcano; it has a volcano" and assured that the north remains entirely safe, with Soufriere under round-the-clock monitoring by a purpose-built observatory.
As is often the way in the aftermath of disaster, the close-knit community has forged stronger bonds than ever.
Crime is a rarity, front doors are unlocked, songs of hope and healing, solidarity and unity, are ubiquitous.

These days, the "emerald isle" is carving a niche for itself in adventure tourism with holidaymakers attracted to its "black sand" beaches and the allure of experiencing a modern-day Pompeii.

Future plans

In the ruined Montserrat Springs hotel - once one of the island's finest - visitors can scrabble through the ash into the reception where paperwork still sits on the desk and into bedrooms where curtains hang against wrecked walls.

From the side of the ravaged swimming pool, Plymouth is visible just east of a huge fissure which appears in the desolate landscape like a jaw wide open in astonishment.
Veronica Hickson's house is one of the few in Plymouth that's not completely buried.
She recalls the evacuation order that came on 3 April 1996. "I've been back since to see my house," she says. "It's sad but we have to continue our lives."

In addition to tourism, hope for the future lies in geothermal energy exploration and the exportation of volcanic sand for construction.
Islanders are keen to reduce reliance on Britain for financial help - £420m ($655m) since 1995.
Former Governor Frank Savage, who presided over affairs from 1993 to 1997, recently paid tribute to the "stoicism" of Montserratians and their "indomitable spirit" which he said would lead to ever greater recovery.
New Governor Elizabeth Carriere, who takes up position this month, agrees. "Montserrat's future lies in the hands of its most valuable resource: its people," she said.
"I will work with the island's government to realise a safe, sustainable and prosperous Montserrat."
Ms Carriere added: "Better sea links, tapping opportunity for geothermal energy and improving technological links to the wider world all have a part to play."
