pygmt.datasets.load_japan_quakes()[source]

Load a table of earthquakes around Japan as a pandas.Dataframe.

Data is from the NOAA NGDC database. This is the @tut_quakes.ngdc dataset used in the GMT tutorials.

The data are downloaded to a cache directory (usually ~/.gmt/cache) the first time you invoke this function. Afterwards, it will load the data from the cache. So you’ll need an internet connection the first time around.

Returns

data (pandas.Dataframe) – The data table. Columns are year, month, day, latitude, longitude, depth (in km), and magnitude of the earthquakes.
