The data I usually use in seismology

As a seismologist, we use many types of data to infer the deformation of the earth, the earthquake source, the site response, etc. This week, I will start to put together a list of data I used before, and links where I usually get the data. I will slowly update the list every week. This will not be a complete list, it will be just the data I used before. Let's start with the seismic catalog data. 

Seismic catalog data

Data description

The seismic catalog data, it is the catalog contains the information of each earthquake. In the most simple version (the catalog data is more complicated), we need the origin time, location, depth, magnitude sorts of information to identify earthquakes. Of course, there is some other information could be in the catalog, for example, the uncertainties associated with the parameters, the stations used to determine the earthquakes, and so on. The catalog data is a spatial and temporal representation of the earthquakes with many other properties. You can also think each earthquake as an object with various properties. 

Data example

They could be easily put into a table, or a CSV file. One example showing below from USGS:

Where to download

There are many organizations/countries keep different catalogs, globally or regionally, but what we usually use is from the USGS earthquake catalog, you can see the API page for how to get access to the data in a programming way.
