T1 catches it. Scope explains it.
geoshake.org · Live Map · API · Downloads
Desktop tool for deep analysis of earthquakes captured by the GeoShake network. Open source (GPL-3.0-or-later). Runs locally on Windows, macOS and Linux.
Feeds on the public map.geoshake.org APIs: pick a network event, an official catalog earthquake (AFAD/USGS/EMSC) or a single station trigger — waveforms download automatically (SAC, 3-axis, m/s²). Or open local SAC files offline.
- Waveform grid with band-pass presets; gaps stay gaps (never zero-filled)
- Spectrogram + Welch PSD per trace
- P/S phase picking: STA/LTA auto-suggestion + draggable cursors, S-P → epicentral distance (Vp=6, Vs=3.5 km/s)
- Ground motion: PGA / PGV / significant duration, station & event magnitude (GeoShake anchored-attenuation v1, UNCALIBRATED), approximate MMI (Worden 2012)
- Verification: side-by-side with the official catalog (Δt, Δepicenter, ΔM), distance-sorted record section
A real M3.4 event (AFAD, 2026-08-18, Halkapınar, Türkiye) captured by station GEO-FVYSA:

Prebuilt packages: grab the latest from Releases — Windows (zip), macOS (zip, Apple Silicon) and Linux (tar.gz). The builds are unsigned for now, so the first launch needs a one-time unlock:
- macOS — move the app to Applications, then either run
xattr -dr com.apple.quarantine "/Applications/GeoShake Scope.app"in Terminal, or try to open it once and allow it under System Settings → Privacy & Security → Open Anyway. - Windows — accept the SmartScreen prompt (More info → Run anyway).
From source — requires uv (Python 3.12 is provisioned automatically):
git clone https://github.com/GeoShake/scope.git
cd scope
uv sync
uv run geoshake-scope

Tests never touch the network. Be polite to the public API: the tool caches every downloaded SAC on disk and endpoints are IP rate-limited.
Scope analyzes what GeoShake T1 stations record: a compact seismic station that sets up over Wi-Fi in minutes and streams ground motion to the network 24/7. Get one, put it on your floor, and your own earthquakes show up here.
