PRESTo - Documentation and User Manual. PRESTo User Manual▲. PRESTo v. 1. 0by Luca Elia. What is PRESTo?▲PRESTo is a free and open source software platform for Earthquake Early Warning (EEW) that integrates recent algorithms for real- time, rapid earthquake location, magnitude estimation and damage assessment, into an easily configurable and portable package. It is under active experimentation in Southern Italy on the Irpinia Seismic Network (ISNet) (Satriano, Elia et al.
The software is mainly targeted at: managers of seismic networks, civil protections, owners of seismic sensors, companies providing seismic sensors and data- loggers and scientists in the field of seismology and earthquake engineering who are interested in characterizing within seconds (if supported by an adequate network infrastructure) the damaging potential of an occurring earthquake, with the possibility to provide personalized alarm messages to any number of end- users. PRESTo in fact continually processes the real- time streams of ground motion recorded by the seismic stations (e. P- waves arrival detection. These data are normally streamed in real- time from the stations using a Seis. Com. P server via the Seed. Link protocol, but they can also be read from files (in SAC format), in order to provide a simulation mode whereby waveforms of past events can be played back into the system. While a (real or simulated) event is occurring, the software promptly performs event detection and provides location and magnitude estimates as well as shaking predictions at target sites.
The earthquake location is obtained by an evolutionary, real- time probabilistic approach based on an equal differential time formulation. At each time step, the algorithm uses information from both triggered and not- yet- triggered stations. Magnitude estimation exploits empirical relationships that correlate this parameter to the filtered peak displacement (Pd) measured over the first 2- 4 s of P- and S- waves signal. Finally, peak ground- motion parameters at remote sites can be estimated through ground motion prediction equations once location and magnitude are available. Alarm messages containing the evolutionary estimates of source and target parameters, sent over the internet, can thus reach vulnerable infrastructures at a distance before the destructive waves, enabling the initiation of automatic safety procedures. This manual provides an end- user guide to the deployment of PRESTo in a seismic network and to its configuration, as well as a description of the algorithms currently implemented, which are summarized in Table 1.

Technology▲PRESTo is written in C++, a programming language that provides optimal speed performance (a key element for an early warning system) without sacrificing the code expressiveness, thanks to its object- oriented nature. The code is easily portable to different operating systems, thanks to the SDL library (Simple Direct. Media Layer), used for abstracting low- level operations, and the Open. GL libraries, a de facto standard for scientific and interactive visualization. Executables are currently available for Windows, Linux (Ubuntu) and Mac OS X. The software is organized into a main thread that implements the core processing procedures activated during an event, and some additional processing threads that handle the continuous tasks, such as waveforms acquisition, using the Seed.
Link protocol, and their processing. Running PRESTo▲Quick Start Guide. You’ll find more detailed instruction below. Anyway, for reference, here’s a quick round- down of the steps needed to run your first PRESTo simulation as quickly as possible, under Windows (Linux and Mac are similar). Extract the PRESTo distribution archive in its own directory, e.
C: \PRESTo. The archive includes an example earthquake occurred in ISNet. The waveforms for this event are stored in C: \PRESTo\data\ISNet\example, along with the "real" source parameters (example_real. ISNet Bulletin). To simulate the earthquake open a command prompt, and type. C: \> cd C: \PRESTo. C: \PRESTo> PRESTo. ISNet example. A window should open up, showing the waveforms streaming from every station (vertical components).
Eventually the earthquake should be detected and processed. PRESTo can then be terminated by closing its window, or pressing Shift- ESC. The results of the simulation will be found in the C: \PRESTo\data\ISNet\example directory. To configure PRESTo for your seismic network and run your first simulation using the waveforms recorded at your stations. Open the PRESTo\data directory. Copy the ISNet directory to network- name, where network- name is a name of your choice for the seismic network (with no spaces), and open the network- name directory.
Create 3. D travel- time grids for P- and S- waves at all your stations and targets, using the Non. Lin. Loc software. This will require their coordinates and a suitable 1.
D velocity model. The file names will be: layer.< P|S>.< station>. Place them in the time directory (delete the ISNet ones first).
Edit the list of location grids for all stations and targets at the top of rtloc. Place the SAC files in earthquake- name, where earthquake- name is a name of your choice identifying the event (with no spaces). The filename extensions must be ". SAC"). The station name is read from the header (KSTNM). The component is assigned according to the last letter of the component name in the header (KCMPNM) i.
Z", "N" or "E". Otherwise the component name is guessed from the filename (i. Z.", ". U.", ". UD.", ". N.", ". NS.", ". 1." means North- South; and ". E.", ". EW.", ". 2." means East- West).
Edit the details of the stations in stations. The conversion factor from counts to m/s. The sensor constant converts from e. Volts (V ⋅ s. 2/m), and the data- logger constant converts from Volts to counts (V/count).
If the SAC files are already in m/s. If they are in cm/s.
Launch PRESTo (PRESTo. It should process the event, or a dialog box will pop- up pointing out a configuration error to fix. In that case edit the configuration files as appropriate and re- launch the application for the new parameters to take effect.
Optionally, you can change the map background by replacing map. The exact longitude and latitude ranges are given in the log file, along with Google Maps links appropriate for your location grid. The root directory (e. C: \PRESTo) contains the executable (PRESTo. The following chapters discuss how to configure the software. To run the program open a command prompt and use the following syntax. C: \PRESTo> PRESTo.
Network- name is the name of the network, the description of which must be found in a data\network- name directory. Earthquake- name is the optional earthquake to be simulated, using SAC files from directory data\network- name\earthquake- name.
Simulation Mode. When an earthquake name is provided as second parameter, e. C: \PRESTo> PRESTo. ISNet example. PRESTo will run in simulation mode, and will perform the playback of all the SAC files it finds in data\network- name\earthquake- name (data\ISNet\example in this case). It will open up a graphical window like the one below: A log file named data\network- name\earthquake- name\earthquake- name. SAC files in the earthquake directory must have ".
SAC") extension. The station name is read from the header (KSTNM). The component is assigned according to the last letter of the component name in the header (KCMPNM), if it is either "Z", "N" or "E". Otherwise the component name is guessed from the filename (i.
Z.", ". U.", ". UD.", ". N.", ". NS.", ". 1." means North- South; and ". E.", ". EW.", ". 2." means East- West). Make sure there is only one file per component per station, or PRESTo will complain about duplicate component. Real- time mode. If no earthquake- name parameter is provided, for instance. C: \PRESTo> PRESTo.
ISNet. PRESTo will run in real- time mode, streaming ground motion data from the internet via the Seed. Link protocol, using the stations specified in the network description. It will open up a graphical window and start a log file in data\network- name\date_time_realtime. User interaction. Click on an element in the window (waveforms, map, magnitude graph) to zoom it in/out.
Click on the "m/sn" button to toggle the seismogram units between counts and acceleration (or velocity). In playback mode only, click on "Pause" to pause the simulated time, or on "Restart" to restart the simulation. In addition the following keys can be used: Key. Description. Shift- ESCTerminate the program (same as closing the window)PPlayback only: toggle pause (same as pressing the on- screen button). Shift- P (or Ctrl- P) will advance simulated time in half second steps.
