Volcanos and tsunamis are natural disasters that most probably generated by earthquakes and south America is considered the most effected region recorded in the past. South America has suffered many earthquakes throughout the history and witnessed huge loss in terms of economy, man force and resources etc.
In the recent years, the western and the northern part of the south America has witnessed some tremendous earthquakes across the continent through which the economy of the state has drastically move downwards and caused huge damage of billions of dollars.
The agency of USGS that take accountability of seismic activity of the continent stated their proposal that in order to overcome the damages from the past and upcoming in the future can be compensate and prevented by making discussion’s that should be based on proper knowledge and research that where the earthquakes can occur in future and how often they might be occur and how strong their magnitude would be.
Part of South America Likely to Experience Earthquakes Volcanoes and Tsunamis: USGS research
In order to determine that which part of south America is most likely to experience earthquakes, volcanos, and tsunamis the agency USGS has conducted thoroughly research in collaborating with the management of the south America continent and succeeded in developing the models and strategies to enhance the efficiency of emergency planning effort of nationwide.
While if we have a look on the local research studies that had been conducted on the basis of damages caused by earthquakes then the study based on five methodology principles which are follows as:
- The newest updated catalog of USGS .
- Record of the USGS over the past 30 years in collaboration with the local scientists/researchers of the south America continent and new models with mapped faults.
- The latest USGS ground seismic motion models that have applied in the hazard maps.
- USGS PAGER susceptibility models (“PAGER” full abbreviation is the Prompt Assessment of Global Earthquakes for Response, and it is a system that provides mortality and economic loss that possess estimates following significant earthquakes worldwide)
- All the applied methods in the U.S. building codes.
The local study research of the south America continent is hardly evaluated and uniformed about the earthquakes that caused shaking hazards and risk, but it is the first report through which the management have succeeded in standardizing applicable methodologies and models to take over the risks and hazards.
It is because of the report that the management is able to reduce the inconsistencies throughout the continent, and to target the regions that are in sake of high hazard and risk within the continent.

It has been concluded from the research that over 160 million people (or can be said that the third of the total population of South America) live in the areas that effected with considerably higher seismic hazards, principally inside the northern and western portions of the continent.
These are the sites where earthquakes caused shaking of grounds resulting tsunamis are termed as most common areas.it does not mean that only the coastal areas are at risk of hazard. Countries such as Venezuela, Colombia, Ecuador, and Peru could also face high hazard and risk
Chile also faces high hazard, but the vulnerability of buildings is much lower compared with the northern countries due to modern and stringent building codes.
Hence it is dictated from the research that the areas of northern and western part of south America where the seismic activities are not in favorable range is at stake of experience earthquakes, volcanos, and tsunamis.
