Exercise/Example: the biggest Earthquake in the UK this Century

The Problem

GeoJSON is a json-based file format for sharing geographic data. One example dataset is the USGS earthquake data:

In [1]:
import requests
quakes = requests.get("http://earthquake.usgs.gov/fdsnws/event/1/query.geojson",
                      params={
                          'starttime': "2000-01-01",
                          "maxlatitude": "58.723",
                          "minlatitude": "50.008",
                          "maxlongitude": "1.67",
                          "minlongitude": "-9.756",
                          "minmagnitude": "1",
                          "endtime": "2018-10-11",
                          "orderby": "time-asc"}
                      )
In [2]:
quakes.text[0:100]
Out[2]:
'{"type":"FeatureCollection","metadata":{"generated":1548076002000,"url":"https://earthquake.usgs.gov'

Your exercise: determine the location of the largest magnitude earthquake in the UK this century.

You'll need to:

  • Get the text of the web result
  • Parse the data as JSON
  • Understand how the data is structured into dictionaries and lists
    • Where is the magnitude?
    • Where is the place description or coordinates?
  • Program a search through all the quakes to find the biggest quake
  • Find the place of the biggest quake
  • Form a URL for an online map service at that latitude and longitude: look back at the introductory example
  • Display that image
