About

Since 2021, the SED-ETHZ SeisComP EEW framework includes two EEW algorithms, the Virtual Seismologist and the Finite-Fault Rupture Detector. They are supported by generic pre-processing and post-processing modules. Their architecture is designed to be flexible and extensible to also include other EEW algorithms in the future.

The architecture of the SED-ETHZ SeisComP EEW package is based on a common, generic envelope processing library, compiled within the sceewenv module, that generates real-time envelope values for horizontal and vertical acceleration, velocity, and displacement from raw acceleration and velocity waveforms. The envelopes are uses by two EEW algorithms:

In addition, the sceewlog module creates log output and mails solutions once a new event is fully processed. It also provides an interface to send alerts in real-time.
