Were there more earthquakes in October than in September 2017?
As in the September earthquake data with a magnitude greater than 4.5 on the Richter scale, for the 30 days prior to 2nd of November was downloaded.
Up-to-date earthquake data is available from the USGS site (United States Geological Survey). From this data, we create two visualizations/maps.
The FIRST is an interactive, but static, map showing some 377 earthquakes with a magnitude greater than 4.5 on the Richter scale. This is 81 less than the 458 in September.
Further, using the widgets (map tools) we can determine that the strangest in October was M6.8 when we compare it to M8.1 in September.
The map can also determine that there were 30 earthquakes in the range M5.4 – 6.8. Compare that to 49 earthquakes in the range M5.2 – 8.1 in September.
The SECOND map is also an interactive, but this time animated, map again showing earthquakes with a magnitude greater than 4.5 on the Richter scale.
The greatest number of earthquakes in October was on the 31st of October with 31 earthquakes.
The greatest number of earthquakes in September was on the 8th of September with 55 earthquakes.
The timeline at the bottom of this map is animated showing the earthquakes in a time sequence as they happened. You can pause the timeline, and then the time cursor can be moved manually. As a result you can see earthquakes occurring by day.
