Multiple Hazards in Cities: Examples from London, Mexico City and Los Angeles


London has experiences a variety of hazards for a long period of time.

* Royal decree in 1306 banned burning of coal to reduce air

* The Great Fire of London which burned over 13 200 homes

* The little ice age which caused the Thames to freeze over

* The Blitz of WW2 which destroyed many homes and industry

* High tides and storm surges

* Smog, especially in the late 50's.

London is prone to storm surges due to a combination of reasons;

* Rising sea levels

* Down tilting of the south of England (isostatic uplift)

* Long-term subsidence.

Smog has occurred as a consequence of all of the pollutants pumped

into the air around London. Some of the worst were in December 1952,

* Visibility was down to 5m

* Fog had a pH of 1.6

* There were nearly 4000 deaths.

To tackle this problem the following strategies were introduces;

* The 1956 clean air act banned coal fires and provided financial
assistance to households to convert to smokeless fuel

* Houses prompted to convert to oil and gas

* Legislation reducing the sulphur content of oil to 1% also helped.

As a result the pollution in London dropped dramatically and continued

Throughout the 80's.

However the smog's returned in he 90's, but rather due to industry it
was due to the large number of vehicles in London. The government
attempted to reduce he pollution levels in a number of ways;

· Variable speeds on the M25 to reduce traffic jams

· Pedestrianisation of shopping areas

...l coverage from space

* Hazard zonation maps

* The monitoring of active volcanoes all help in managing the crisis
when it has happened.

Flooding is common in the Philippines due to tsunamis and typhoons.

Lowland floodplains can't cope with the huge amounts of water. The
result of flooding e.g. in July 1972, 600 were left dead, 370 647 were
left homeless and 200 000 ha of crop land was destroyed. This resulted
in £20 million of damage to roads, bridges and infrastructure.

Drought is also a problem as there are often several months with very

rainfall (up to 40% less). The last significant drought was in
December 1986 when most of the country was affected. In 1989 a drought
weakened the economy with a loss of agricultural production, just
before the 1990 earthquake and the 1991 eruption.

Luis Valdez's Los Vendidos Essay

- Luis Valdez's Los Vendidos Social science teaches that a person’s self identity is a reflection of that which other people put on the individual, in other words a person’s behavior steams more from what they see of themselves from someone else’s perspective and less from how they see themselves.

Essay on Why is Mexico City in Peril?

- The old city of Tenochtilàn is not what it used to be. To begin with, it has a new name: Mexico City or the doomed city as people would like to put it. But it is not doomed on account of a joint Russian-Chinese invasion. No, it’s doomed because of what it is, and let me tell you, Mexico City is something. To fathom the sheer massiveness of the cities current population and density is to sit in awe and wonder if the people are squashed into large anchovy tins. Many factors led to the sad state that is Mexico’s today....   [tags: Mexico]

Essay on The Rise Of Mexico : Alliances Of Power

- The Rise of Telenovelas in Mexico: Alliances of Power Telenovelas are seen as a genre – a soap-opera style of television with wild theatrics, colorful sets, and a romance-oriented storyline. However, telenovelas are much more inclusive and can be considered a format, rather than a genre, due to the fact that there have been telenovelas that have been mysteries, horror shows, and action-oriented, rather than the traditionally recognized “romance”. A question that I will attempt to answer in this essay is: why did telenovelas become so popular in Mexico when they emerged in the late 1950s....   [tags: Mexico, United States, Spanish language]
