Landslide buries 14 in Ecuador

Tuesday night a landslide in Esmeraldas Ecuador buried two homes at the bottom of a mountain killing at least 14 people.

The area had been experiencing pouring, steady rain showers for over 2 hours which loosened the mountain side enough to cause a landslide. Crews were sent out almost immediately to search for potential survivors. This source http://www.ecuadortimes.net/2013/04/25/thirteen-victims-is-the-balance-of-a-landslide-in-esmeraldas/ explains that in one of the excavated homes a couple and their young baby were found huddle together, apparently having known there was no hope to escape the mud. Original reports stated that 13 bodies were found among the rubble, but

From what I have found through quick research, Esmeraldas is a coastal city but highly agricultural. So, if the land is being depleted of vegetation on steep slopes or higher up from where this slide occurred, the lack of proper drainage could have encouraged the slide. But this is just my own speculation.

Warmest waters in Atlantic Ocean in 150 Years

During the second half of 2012, the Northeast coast of the Atlantic Ocean has recorded the warmest sea surface temperatures in 150 years. The average sea surface temperature for the past 30 years was recorded at 54.3 degrees Fahrenheit  where as in the latter half of 2012 it was recorded at 57.2 degrees Fahrenheit. This has been the largest jump in temperatures warming and is has greater warming then any other ocean in the world. This warming of the Northeast coast has influenced the distribution of some fish populations as they begin to shift northward. Two examples of fish populations moving north are the black sea bass and the summer flounder. This warming has scientists curious on if the ecosystem of the coast will change. These findings were reported on April 25th by NOAA’s Northeast Fisheries Science Center.

Weather ‘Whiplash’ Hits the U. S. Midwest.

I found this to be an interesting story that shows just how fickle mother nature is. Just a few months ago barges were scraping bottom on the Mississippi River, and the Army Corps of Engineers was blowing up rocks on the bottom of the river to allow shipping to continue. Water levels on the Mississippi River at St. Louis bottomed out at -4.57′ on January 1 of 2013, the 9th lowest water level since record keeping began in 1861, and just 1.6′ above the all-time low-water record set in 1940.  But the exceptional April rains and snows over the Upper Mississippi River watershed will drive the river by Tuesday to a height 45 feet higher than it was on January 1. The latest forecast calls for the river to hit 39.4′ on Tuesday, which would be the 8th greatest flood in history at St. Louis, where flood records date back to 1861. Damaging major flooding is expected along a 250-mile stretch of the Mississippi from Quincy, Illinois to Thebes, Illinois next week. In addition, record flooding is expected on at least five rivers in Illinois and Michigan over the next few days. A crest 1.5′ above the all-time record has already occurred on the Des Plains River in Chicago. A crest on the Grand River in Grand Rapids, Michigan nearly 4′ above the previous record (period of record: at least 113 years) was expected this weekend. At this flood level, major flooding of residential areas is expected, though the flood wall protecting downtown Grand Rapids will keep the commercial center of the city from flooding. Residents along the Mississippi River have experienced a severe case of flood-drought-flood weather whiplash over the past two years. The Mississippi reached its HIGHEST LEVEL ON RECORD at New Madrid, Missouri on May 6, 2011, when the river crested at 48.35′. Flooding on the Mississippi and Missouri rivers that year cost an estimated $5 billion in damages and economic loss.

New Grass Could Cut Back on Flooding

Recently, rainfall levels have risen in the UK risking a lot more floods to occur. However scientists from the Biotechnology and Biological Sciences Research Council have found a new type of grass that can stop water from running off fields. The grass is a hybrid of rye and fescue (rye is grazed a lot by cattle and fescue grows deep roots) and creates a lot more pores in the soil than normal grass, which allows more water to be stored in the ground. The grass had been tested for two years and was found to reduce run-offs by 50 percent. “with 69% of the world’s agricultural land being grassland,” said Kit Macleod, a hydrologist at the James Hutton Institute in Aberdeen. “The new hybrid had significant potential as a plant that could simultaneously provide good forage for livestock, be resilient to increasingly extreme weather and provide flood protection.”

Rather than mitigating natural disasters through man-made structures, this natural approach is more intriguing and more appreciated by everyone, especially farmers. Also it teaches us that we do not need to resort to “fixing building fixing building”, which is what we do a lot as humans. We are learning to work with nature by finding all its potentials.

Drought in New Zealand

New Zealand has been experiencing some extensive drought since February. This summer, (since they are in the southern hemisphere) has been particularly bad for them; the drought situation on North Island, NZ has experts calling it the worst drought in 70 years according to the article below. They attribute this to a high pressure system that has been lingering over the country during this time. As of this week, they are finally getting some badly needed rain. The drought has caused problems for the dairy industry in New Zealand, that relies on grasses and pastureland for cows to eat and produce milk. They are warily optimistic, to finally get some rain, but will continue to monitor the situation over the next six weeks or so, which will determine if things will be good enough for optimal grazing. Milk production for this season could be down 1-2% compared to last season.

This first link has a cool photo comparison, showing satellite images from before the drought in 2009, which was a more normal year for climate, versus April 2013.

Disaster Planning in Kenya

With a new government, people in Narobi must improve natural disaster planning. Because of heavy rains since March, the results of these rains have washed out numerous crops, homes, and bridges, not to mention have flooded many homes. The Red Cross have done all they can to provide shelter, food, blankets, and medicine to people who were negatively affected by the floods, but they can only do so much.

Under the new government, the people in Narobi hope to engage in water harvesting and water management. Kenya’s new vice president, William Ruto, hopes to develop a five-year plan to enable more building of dams and dykes to lessen the effects of the torrential rains.

CaseStudySummary_Payne

Anyone who grew up in the central corridor of the east coast remembers the Blizzard of 1996. Even as a 5 year old I remember running and jumping off the porch into 2.5’ of snow and having to get my dad to pull me out by my arms. It was a dream for any school-aged child, but a detriment to the citizens, government, and economy of the eastern U.S.

The Blizzard of 1996 slammed the northeast corridor for 3 days before it subsided, only to be followed up by smaller storms over the next week. The storm began January 6, 1996 as a low pressure system off the coast in the Gulf of Mexico. Meanwhile, several other low pressure systems were also forming within an inverted trough system. The system moved east-northeastward until it suddenly changed directions on January 7, 1996 as additional low-pressure systems popped up along the Virginia/North Carolina coast. Initially, the storm had been following a route from the Gulf over Tennessee and into the Northeast. But, very low surface pressures formed over eastern Georgia and Cape Hatteras, North Carolina. This coastal front in combination with the low pressure system heading right for it, turned out to be the perfect combination for an intense blizzard. Once the front reached Cape Hatteras, it hit the moist coastal front and became stagnant. Temperatures to the north of the storm had dropped substantially as artic air moved through the region. Before meeting the coastal front and artic air, forecasters had predicted that it would head out into the Atlantic, and then it changed its path—heading straight towards Washington.

[Because the blizzard caused such a ruckus all along the east coast, Virginia and Maryland will be the focus of this blog post. ]

 

On January 3, most areas along the east coast were aware that a winter storm was moving towards the area, yet only the southern-most areas of Virginia were placed under a Winter Storm Watch beginning January 5. At this point in the storm’s development, many forecasters and meteorologists were arguing over the potential direction and impacts of the storm. It was unclear where the storm was exactly headed and what areas should be warned of the impending storm. By January 6 the storm-tracking models began to show that the storm was going to be hitting much farther north along the coast than was originally anticipated, and the entire state of Virginia and most of Maryland (though the northern-most parts of Maryland soon joined)was then placed under a Winter Storm Warning. However the January 6 warnings did not stop there, the storm and coastal front were causing winds to rip across the coast, forcing officials to also issue Gale Warnings and Coastal Flood Warnings. A Blizzard Warning went into effect the morning of January 7. The storm hit the southwest region of Virginia less than 24 hours after the issue of the winter warning and spread quickly to the DC area, dropping upwards of 2 feet of snow as it moved into Pennsylvania and New York. On January 8, as the storm continued its move northward and winds began blowing offshore behind the storm, the region was relinquished of all warnings.

Following the storm, NOAA conducted a Service Assessment on the response of emergency officials, media and forecasters in regards to how well they prepared citizens before the blizzard hit the area. According to the report, the National Weather Service Forecast Office had a false alarm rate of 0%, meaning that every area (at least for the Virginia, Maryland and DC region) that was forecasted to be hit by the storm was, indeed, buried by snow. In addition to national forecasts, local governments acted unusually quickly and organized grassroots clean-up crews, hiring locals to man the 300+ snow removal equipment rented by VDOT shortly before the onset of the snow.

VDOT workers already on payroll took the days prior to the storm off to secure shelter and subsidence for their families, allowing them to work long hours once it was time to clean-up after the blizzard. Meteorologists and storm-watchers bunked in their offices to assure that they could keep the public up-to-date on the on-goings of the storm. The report also notes that following the blizzard of 1993, VDOT, the Virginia government and the National Weather Service began working together to prepare for storms such as this which allowed them to better communicate and coordinate needed services.

In the end, the blizzard caused the DC Metropolitan region to shut down for 3 days, including the federal and local governments. With the entirety of the region under at LEAST a foot of snow, airports and metros were at a standstill for almost a week. Most businesses including many flat-topped grocery and retail stores had to close until the snow was cleared from their rooftops for fear that the roof may collapse in on customers. This had a huge negative impact on the economy, as businesses in the area were already suffering from loss in sales.

In total, 18 people died in Virginia during the storm, 3 from hypothermia, 1 from a tree falling atop his car, and 10 from heart attacks while shoveling snow. Maryland saw 13 death from snow shoveling and 1 from a metro accident due to snowy conditions.

Following the blizzard, the region experienced smaller snow-storms which made clean-up difficult. Winds carrying the snow would blow 5-8 foot drifts into road ways and yards. The additional weight of the snow caused more collapsed roofs and damaged to properties.

Chinese Earthquake Relief Workers Battle Landslides

After a disastrous earthquake in the Sichuan province of China has led many in need of help, the only problem is that rescuers have been hampered by clogged roads, debris and landslides as they search for survivors of the powerful earthquake in mountainous southwest China that has left at least 192 dead. Huge boulders blocked rescue vehicles along roads leading to some of the worst-hit areas, and some areas were only accessible by foot along broken passes through the rough terrain. Survivors including the elderly were carried out on the backs of neighbors as well as by helicopter, as rescuers were also bolstered by thousands of civilian volunteers who rushed to the area to help. State broadcaster CCTV showed orange-suited emergency workers making desperate dashes past cliff-edges, trying to avoid sudden landslides in a region weakened by more than 2000 aftershocks. Industrial diggers clawed through debris including the mangled remains of cars and motorbikes crushed by tumbling rocks, to clear roads also clogged by huge queues of traffic.

The 6.6-magnitude quake which hit Sichuan province on Saturday has left another 23 missing and more than 11,000 injured, while some 17,000 families have lost their homes. Forecasts of rain in the disaster area raised fears of more deadly landslides that could cause further mass movements.  This situation is a perfect example of how a natural disaster can create conditions that are prime for more natural disasters. Being weakened by the earthquake Chinese citizens are now more vulnerable to these landslides because of the damage already done to the local infrastructure.

Mulch fire in Maryland

Investigators are still trying to determine what caused this fire that started on Wednesday night. A huge pile of mulch 500 feet wide and 50 feet tall caught fire in a rural part of Prince George’s County, Maryland. It took firefighters about 12 hours to put it out while they battled awful conditions for fire fighting. They were dealing with high winds that would blow embers and start additional small brushfires and the landfill is located very far from water sources. They had to use 9 tanker trucks to haul water from a mile away. They also used a massive hose to get water from a nearby school. The article says that these types of fires are common because the mulch is decaying and releasing heat. Workers are putting soil on top to hopefully prevent the fire from starting up again. Officials say that they will continue to monitor the situation. Luckily nobody was injured and the fire didn’t spread into nearby lands. It could have been much worse.

Heavy Rain Floods Northern Vietnam


Torrential rains as well as heavy winds poured into the Vietnamese Lam Binh district (province of Tuyen Quang), Xin Mân (Ha Giang) and Si Ma Cai (Lao Cai). This caused heavy flooding and according to the preliminary assessment of the Steering Committee, which helps towns in the prevention and fight against floods. It has been reported that 74 houses were destroyed and dozens of rice and vegetable crops have been ravaged. A similar occurrence has happened to 16 other towns on the Mân Xin District. There have been no reported deaths or injuries, however the storm has cause severe damage to a radio station and local school building.
