One came with this story about a practical application of big data
analysis as applied to the trove of sensor readings taken by satellites
and by ground-based senosrs. A company called Terra Seismic says that
earthquakes can be predicted 20-30 days before they occur,
by sifting data for thermal, ionic, and other abnormalities in areas
where quakes are considered likely. Says the linked article: "The
company claims to have successfully predicted a number of earthquakes.
For example, on 5th of April 2013, the firm issued a forecast for Japan.
On 12th April 2013, an earthquake hit the identified area and 33 people
were injured. On 4th June 2013, the firm again made a prediction for an
earthquake in North Italy. On 21st June, an earthquake hit the
identified area. On 3rd March 2013, the firm issued a forecast for an
earthquake in Iran. Again, after 35 days, an earthquake hit the
identified area."
