OpenEEW package for Python

The OpenEEW package for Python contains a collection of tools for working with OpenEEW, including:

• Downloading and analyzing accelerometer data
• Real-time data processing
• Detection algorithms

Currently it provides a client to simplify downloading data held as an AWS Public Dataset. See here for information about how data is organized.

More features will be coming soon.

Some additional resources:

• Package documentation
• OpenEEW GitHub repository

Installation

The package can be installed using pip (for a suitable version of Python):

pip install openeew

Usage

Here is an example of how the package can be used to download data for a chosen date range.

First import the AwsDataClient class:

from openeew.data.aws import AwsDataClient

We initialize a data client object by specifying the required country, either mx for Mexico or cl for Chile:

data_client = AwsDataClient('mx')

To get a list of current devices:

devices = data_client.get_current_devices()

To get data for a specific (UTC) date range, first specify the start and end dates:

start_date_utc = '2018-02-16 23:39:00'
end_date_utc = '2018-02-16 23:42:00'

Then call the get_filtered_records method:

records = data_client.get_filtered_records(
  start_date_utc,
  end_date_utc
  )

We can also get the data as a pandas.DataFrame:

from openeew.data.df import get_df_from_records

records_df = get_df_from_records(records)

It is also possible to specify a list of device IDs:

records = data_client.get_filtered_records(
  start_date_utc,
  end_date_utc,
  ['001', '008'] # optional list of device IDs
  )

A single device ID can be passed as a string:

records = data_client.get_filtered_records(
  start_date_utc,
  end_date_utc,
  '001' # optional single device ID
  )

We can change the country if we want. So if we now want to look at Chile data:

data_client.country_code = 'cl'
