A series of floods and mudslides occurred in January 2011 in several towns in Rio de Janeiro, Brazil. Over 900 people were killed, with the worst impacts in Nova Friburgo and Teres坦polis where over 400 and 378 people died respectively. The disasters were triggered by over 26cm of rain falling in under 24 hours, more than an entire month's worth of rain. Whole families and homes were buried by cascades of mud and debris. The Brazilian government provided emergency relief funding and assistance with reconstruction efforts.

CASE STUDY - Non cyclonic storm and landslide in Brazil 2011 I-Abstract A series of floods and mudslides took place in January 2011 in several towns of the Mountainous Region (Regi達o Serrana), in the Brazilian state of Rio de Janeiro. Casualties occurred in the cities of Nova Friburgo, Teres坦polis, Petr坦polis, Bom Jardim, Sumidouro and S達o Jos辿 do Vale do Rio Preto. The floods caused at least 903 deaths, including 424 in Nova Friburgo and 378 in Teres坦polis. While local media claims that the combination of floods, mudslides and landslides in Rio de Janeiro became the worst weather-related natural disaster in Brazilian history, some contend that a similar weather-related tragedy that took place in the same state in 1967 was much deadlier, and that an estimated 1,700 people lost their lives on that occasion. In a 24-hour period between 11 and 12 January 2011, the local weather service registered more rainfall than what is expected for the entire month. Flooding of many areas in the region followed immediately. The disaster caused widespread property damage and the supply of public utilities such as electricity, running water and phone lines was affected. Around 2960 people had their homes destroyed. President Dilma Rousseff declared that an emergency R$ 780 million (U.S. $466.2 million) would become available for reconstruction workers. Acting governor Lu鱈s Fernando Pez達o sent reinforcements to the affected region and requested urgent federal assistance in machinery, helicopters and manpower. 3
II-Problem Statement The causes of landslides are usually related to instabilities in slopes. It is usually possible to identify one or more lansdslide causes and one landslide trigger. The difference between these two concepts is subtle but important. The landslide causes are the reasons that a landslide occurred in that location and at that time. Landslide causes are listed in the following table, and include geological factors, morphological factors, physical factors and factors associated with human activity. Causes may be considered to be factors that made the slope vulnerable to failure, that predisposethe slope to becoming unstable. The trigger is the single event that finally initiated the landslide. Thus, causes combine to make a slope vulnerable to failure, and the trigger finally initiates the movement. Landslides can have many causes but can only have one trigger as shown in the next figure. Usually, it is relatively easy to determine the trigger after the landslide has occurred (although it is generally very difficult to determine the exact nature of landslide triggers ahead of a movement event). In meteorology, a cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure. . All large-scale cyclones are centered on low- pressure areas The largest low-pressure systems are extratropical cyclones of the largest scale Warm-core cyclones such as cyclones and subtropicalcyclones also lie within the synoptic scale Mesocyclones, tornadoes and dust devils lie within the smaller mesoscale Upper level cyclones can exist without the presence of a surface low, and can pinch off from the baseof the Trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, 4
III-BACKGROUND INFORMATION Torrential rainstorms, which began yesterday, triggered a series of deadly mudslides in at least three mountaintop towns to the north of Rio. Dozens of people were buried alive as they slept, among them children. The mountains saw 26cm (10in) of rain fall in less than 24 hours. The worst hit area was Teres坦polis, a popular hillside tourist town around 60 miles north of Rio where at least 130 residents were buried under cascades of terracotta mud and debris. Whole families were buried alive while at least 2,000 people were reportedly forced from their homes. "My friend has lost 15 relatives today," said Andreia Mattos, who was spending her 45th birthday outside the city's morgue last night surrounded by masked doctors and weeping locals desperately seeking information about missing relatives. "It wasn't just the poor who were hit - it was mansions, everything. It all came down. 5
IV-FINDING During my unfortunate lull in posts an extraordinary landslide disaster has of course unfolded in Brazil, killing at least 700 people, and possibly more than a thousand. The trigger has been very heavy rainfall associated with the current La Nina conditions, although the underlying cause is likely to be a combination of people living in the wrong places and damage to the environment as a result of human activities. The epicentre has been the three towns of Nova Friburgo, Teresopolis and Petropolis, located to the north of Rio de Janeiro. So lets take a look at Nova Friburgo. A 7.0 magnitude earthquake shook the remote border region of Acre in the Brazilian Amazon at around mid-day yesterday. Telephone lines are down and there are reports of minor damage to houses. As yet, no serious casualties have been reported. Tremors were felt in the town of Cruzeiro do Sul, in the state of Acre, Brazil, News Tremors were felt in the town of Cruzeiro do Sul, in the state of Acre, Brazil, image by earthquake.usgs.gov. According to data from the U.S. Geological Survey the quake originated in the town of Pucallpa, in a sparsely populated central-eastern region of Peru on the border with Brazil, some 600 km (370 miles) from the Peruvian capital Lima. Shock waves were felt up to 210 km (130 miles) from the epicenter, in the town of Cruzeiro do Sul in the state of Acre. However, seismologists are not anticipating major damage because the earthquake occurred almost 145 km (90 miles) 6

Next to her crying women leafed nervously through an A-4 notepad filled with pictures of unidentified corpses, bloated, mud-soaked limbs and babies whose smooth faces had been frozen into peaceful gazes by their sudden deaths. Written on the pad's frontcover were the words: "Victims of the natural disaster - 12.1.11". The Guardian counted at least 8 babies among the photographs, as well as toddlers, teenagers and elderly women. 7

A team of workers in the operation had prior experience with the 2010 Rio de Janeiro floods and 2010 Haiti earthquake Analysts have commented that President Rousseff through her management of the crisis "passed... her first big test", but that the structural challenges that make certain (poverty-stricken) areas particularly hard hit in times of environmental disaster, still need to be addressed. At last i want to conclude that the these disasters are a part of nature and one cannot stop them only prevent them by being ready beforehand. 8
