Curated Exercise 02 Answers
investigating the relationship between regional earthquakes and volcanic .. Figure Histogram of spatial range between earthquakes and volcanoes. I chose to compare the relationship between plate boundaries, volcanoes and earthquakes. The layers I chose satisfied the fact that magma. The time correlation between the eruptions of Mt Vesuvius and the occurrence of strong earthquakes in Italy has been revised using new and improved catalogs.
Where are volcanoes concentrated?Volcanoes Iceland, Italy and California Reports of earthquakes
Where are volcanoes rarely located? Using your web browser, go to the website of the United States Geological Survey at www. Click on the link "Real-Time Earthquakes.
The file name will be automatically saved as "1. The file contains earthquake location data provided by the United States Geological Survey.

In the Google Earth sidebar, you will see that the data file shows the locations of earthquakes that have occurred within the past hour, past day, and past week. Using the Google Earth navigation controls, locate and zoom into ten earthquakes. Click on the circular icon for each earthquake to retrieve descriptive information about the earthquake.
In your notebook, create a table that records the location, longitude, and latitude of each earthquake.

Where are earthquakes concentrated? Where are earthquakes rarely located? You will now compare the data on the locations of volcanoes to the locations of earthquakes.
The file should open automatically in Google Earth and the data should be displayed along with the earthquake data. Use the data sets displayed on Google Earth to help you answer the following in your notebook: Describe the spatial relationship between the volcano data and the earthquake data. What explanation can you give for this relationship?

Look at the map Legend to learn the meaning of the various symbols and how to use the map scale. What does each of the four kinds of triangles represent? Use the map navigation controls Zoom in andZoom-out and the Legend to help you examine the locations of volcanoes and earthquakes. Previous works [ 61213 ] noted the correspondence between the seismic transient that took place between and three time the annual rate of destructive earthquakes in respect to the previous period and the occurrence of the Little Ice Age LIA.
Previous works have suggested a possible role of the climate, which could affect both the seismicity and the volcanism through variations of the surface loads sea level, ice at the poles and glaciers and consequent changes of the stress field at depth.
A similar mechanism is supported by a number of geophysical models and statistical studies available in the literature [ 28 ], although most of them e. What outlined is a promising field of investigation, although very problematic.
Just to say, there are a number of climate indexes, most of which are not direct measures but reconstructions obtained by correlation with biological, chemical, and geophysical data.
There is no consensus on the beginning of the LIA as well as on its spatial extension global or restricted to a more limited area, for example, the Euro-Asiatic region and its temporal evolution.
All such complicates the assessment of the time correlation, which is just the first step of the task.

The work [ 6 ] reports some graphical comparisons between Italian seismicity, the global sea level, and the global sea level rate, since More robust statistical methods are adopted in [ 12 ] to assess the degree of correlation between Italian seismicity of the last millennium and a reconstruction of the global surface temperature [ 30 ].
It is possible that other, even more local climate indexes are more appropriate. The resemblance among the three curves is remarkable. In the pre period, they have three common oscillations, although with different amplitude.
