Technological Risks Using technology, Humankind is changing environmental condition and different types and levels of risk situation occur. On the other hand, we have the technical capabilities to try to control these risks.

Natural Disaster
Natural disasters in Brazil are triggered by extreme meteorological conditions and the risks are closely related to land use. Risks can be reduced by simply changing the vulnerability conditions, but it is not so simple.

IMPACT OF NATURAL HAZARDS
CLEAR UNDERSTANDING OF
RISK SCENARIOS
Risk Scenario related to landslide comprises urban
settlements and infrastructure (oil refinery plant,
highways, pipelines of gas, oil and water, eletric
transmission lines and so on).

to infrastructure, exist but
are not effectively available,
for a great number of civil
works

Using Geographical Information
System + Business Intelligence
for Risk Analysis
IPT has a great volume of historical geo-
environmental and technological data from
investigation and analysis which, together
with new data (Big Data) can be effectively
used for Risk Management and Engineering
Planning
Dynamic Risk Analyis to increase the risk control
![Page 31: Natural Disaster Risk Scenario in Brazil - ABC · 2018-03-17 · Natural Disaster Risk Scenario ... (oil refinery plant, highways, pipelines of gas, oil and water, eletric ... products](https://reader034.fdocuments.us/reader034/viewer/2022042419/5f35d9072eb1c423da2c0ffb/html5/thumbnails/31.jpg)
Final Remarks 1. There is a great amount of technical data,
information and products resulted from investigation
and analysis that must be organized to be available
for risk prevention;
2. Risk Scenarios changes dynamically and we need
to use basic knowledge and nowadays technological
advances to proper model, predict and quantify them;
3. Big Data must be continuously collected and
processed by powerful integrated systems in GIS
platform in order to have systematic information
about potential variable risk condition from time to
time and from place to place;
4. Education is an important and cheap way to
enhance the people capability to reduce the impacts
of adverse conditions of the nature.
