Trends in Natural Disasters
The aim of this project is to analyze if there is a relationship between change in average land temperature and the number of tsunamis, number of volcanic eruptions, number of earthquakes with magnitude of 5.5 and higher, and magnitude of earthquakes. We examined how the trends of these events have changed over the years.
Global Temp Changes 1990-2013
There has been an obvious increase in the average land temperature around the globe. More specifically, an increase of about 2°F since 1960. Although this increment has not been steady, it can be seen that the greatest increase in temperature has happened in the most recent years.
Number of Tsunamis over Years
Tsunamis are ocean waves caused by other natural disasters such as earthquakes or volcanic eruptions, that result in the movement of tectonic plates. There has been a general increase in the number of tsunamis over the years around the glove. Even though during some years the numbers are equally low as previously recorded, there has been an obvious increase during recent years compared to the 1990's.
Number of Volcano Eruptions over Years
A volcano is an opening or rupture of the earth’s crust that allows gases, ash and hot lava to escape from below the earth’s surface. Volcanic eruptions are due to increased pressure.
This graph displays the number of fatal incidents recorded in a 23-year period, from 1990 to 2013. The number of volcanic eruptions during this time period is varied, and an increase cannot be established.
Number of Earthquakes over Years
Earthquakes occur frequently in nature, and earthquakes with varied magnitudes around the globe are continuously recorded. For this analysis, we chose earthquakes with magnitudes of 5.5 or higher, during the years 2000 to 2013 for various countries around the globe. It can be seen that the number of earthquakes with a minimum magnitude of 5.5 has increased over the years. Especially during the most recent years, this number has remained relatively high, varying between 9 and 14 events.
