Classroom exercise: 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]

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
