EEW Evaluation

Performance Evaluation Summaries

Two descriptions of performance summaries include:

• CISN Testing Document
• CTC Group Evaluation Collection

We separate the summaries into "Event" Summaries and "Catalog" Summaries where catalog means any set of earthquakes, and the summary must make it clear what criteria were used to define the catalog.

ShakeMap Data

We are currently working with the ShakeMap stationlist txt file. We may convert to the stationlist xml files, but it was easier to parse the column oriented to start.

We have identified several formats to the ShakeMap. Two main formats are the CI: and NN: events, and ECX events. ECX events have their pgv and pga values in different columns than the others, so this type of ShakeMap report must be checked for while parsing.

ShakeMap files also have

Processing Flow

Current design is based on processing one or more trigger reports. Currently two types of trigger reports are supported CIT On Site, and ETH Virtual Seismologist.

1. Init CISN Station list, ANSS EQ catalog, ShakeMap catalog
2. For each Trigger File
   1. Mapped to One or More ANSS Events and observed data from ShakeMap
3. For each event in trigger file
   1. write event summary
   2. Add to catalog summaries
4. write catalog summaries
