How to Access and View Detected Events in SeisComP

SeisComP is a widely used software package for seismological data acquisition, processing, and analysis. One of its core features is the detection and cataloging of seismic events. In this guide, we will walk you through the steps to access and view detected events in SeisComP, and explain where the event catalog is stored.

Viewing Detected Events in SeisComP

Using the SeisComP GUI (Scolv)

The Scolv tool in SeisComP is a graphical user interface designed for reviewing and manually locating seismic events. Here’s how you can use it:

1. Launch Scolv:

• Open a terminal and type scolv to start the application.
• Alternatively, you can launch it from the SeisComP graphical interface if available.

1. Browse Events:

• Once Scolv is open, you can browse through the list of detected events.
• Click on an event to view detailed information such as magnitude, location, and origin time.

Using the Command Line Interface

SeisComP provides powerful command-line tools for querying and managing events. Here’s an example of how to list events using the command line:

Open Terminal:

• Open a terminal window.

Run Query:

• Use the seiscomp command to list events. For example:
  bash seiscomp exec scevtls -d mysql://user:password@host/database
• Replace the database connection string with your actual SeisComP database connection details.

Using the SeisComP Web Interface

If your SeisComP setup includes the web interface, you can access it via a web browser to view detected events:

Open Browser:

• Open your preferred web browser.

Navigate to SeisComP Web Interface:

• Enter the URL of your SeisComP web interface.
• Browse to the event list page where you can filter and view events.

Understanding the Event Catalog Location

The event catalog in SeisComP is typically stored in a database. The type and location of this database depend on your SeisComP configuration:

Database Configuration

SeisComP supports various database backends such as MySQL and PostgreSQL. The connection details are specified in the SeisComP configuration files, usually found in /etc/seiscomp3 or a similar directory.

Configuration File (global.cfg)

To find the database settings, open the global.cfg configuration file. Look for entries like these:

database.archive = mysql://user:password@host/database
database.events = mysql://user:password@host/database

These entries specify the connection details for the event catalog database.

Database Tables

Event information is stored in various tables within the database, including Event, Origin, Magnitude, and more.

Steps to Access the Event Catalog

Ensure SeisComP is Running

First, ensure that SeisComP services are running. You can start them using the following command:

seiscomp start

Accessing Scolv

To access Scolv, open a terminal and type:

scolv

Using the Command Line

To list events using the command line, run:

seiscomp exec scevtls -d mysql://user:password@host/database

Web Interface

Open your web browser and navigate to the SeisComP web interface URL, if configured.

Conclusion

By following these steps, you can easily view the events detected by SeisComP and understand where the event catalog is stored. Whether you prefer using the graphical interface, command line, or web interface, SeisComP provides flexible options to manage and review seismic event data.
