ℹ️ WHAT IT MEASURES
EHZ: High-sensitivity vertical geophone (ground velocity in counts).
ENZ/ENN/ENE: Triaxial strong-motion accelerometers (vertical, N-S, E-W in m/s²).
🟢 WHAT IS NORMAL (AMBIENT)
Quiet background is a thin line (±20–150 counts, <0.0003 m/s²). Footsteps/stairs cause isolated sharp micro-spikes (<0.4s). Passing trucks cause narrow 8–15 Hz wave trains lasting 5–10s.
⚡ WHAT AN EARTHQUAKE LOOKS LIKE
Begins with a sharp, high-frequency P-wave arrival on EHZ/ENZ, followed seconds later by powerful rolling horizontal S-waves on ENN/ENE (3–5x larger amplitude) that slowly decay over tens of seconds.
ℹ️ WHAT IT MEASURES
Real-time 128-bin FFT power spectrum from 0 Hz (bottom) to 50 Hz (top) scrolling over time. Deep Navy = quiet; Yellow/Red = intense seismic energy.
🟢 WHAT IS NORMAL (AMBIENT)
Quiet ambient background is solid deep navy. Heavy diesel trucks create narrow streaks around 8–14 Hz. Greek Theatre concerts appear as low-bass bands around 25–45 Hz. Cal Stadium crowds create 2–8 Hz acoustic hum.
⚡ WHAT AN EARTHQUAKE LOOKS LIKE
A sudden, blazing vertical wall of yellow/red fire spanning all frequencies (0.5 to 25+ Hz), with intense low-frequency resonance (1–5 Hz) that persists across the waterfall for tens of seconds.
🌈 High-Definition Spectrogram & Synchronized Waveform (0–50 Hz)
Continuous STFT energy distribution aligned with real-time ground velocity waveformℹ️ WHAT IT MEASURES
Traditional seismological 24-hour rotating drum record. Each horizontal row is 1 full UTC hour (60 minutes left-to-right). The bottom row is the current hour with the red live stylus needle.
🟢 WHAT IS NORMAL (AMBIENT)
Nighttime quiet hours show clean, thin horizontal lines. Daytime human activity shows gentle thickening (1–2 mm). Hours before station startup remain clean blank paper.
⚡ WHAT AN EARTHQUAKE LOOKS LIKE
A dramatic, spindle-shaped packet with large vertical deflections that may cross multiple rows. Local quakes show sharp onset; distant regional quakes show wide, smooth rolling spindles with gold USGS magnitude pins.
24-Hour Helicorder Drum Record
Continuous 24-hour strip record (1 hour per row). Quakes appear as multi-minute packet bursts crossing rows.
ℹ️ LEFT: STA/LTA (INSTANT TRIGGER)
Compares fast 0.5s sudden ground velocity against 10s background average. Normal is ~1.0x. Sharp P-waves spike vertically past the 6.5x Trigger Threshold.
🟢 RIGHT: RSAM (60-MIN HOME ENERGY)
Real-Time Seismic Amplitude Measurement: Demeaned RMS ground vibration per minute. Cyan/Green (<2x baseline) = your home's quiet ambient baseline (~20–45 counts). Amber (2–5x) = footsteps, wind, or passing delivery trucks. Red (>5x baseline) = true seismic tremors or earthquakes.
🏠 YOUR HOME'S NORMAL BASELINE
Living directly on the Hayward fault zone means your home has natural background hum (wind, doors, HVAC). The engine continuously tracks this dynamic baseline so normal everyday living stays in the green/cyan zone!

3D ground particle motion vector trajectory combining North-South, East-West, and Vertical strong-motion accelerometer axes.
🟢 WHAT IS NORMAL (AMBIENT)
Small random isotropic cluster or jitter centered at (0,0). Local footsteps appear as tiny vertical loops.
⚡ WHAT AN EARTHQUAKE LOOKS LIKE
P-Wave: Elongated linear needle pointing directly along the back-azimuth toward/away from the epicenter. Rayleigh Waves: Retrograde rolling elliptical loop in the vertical plane.

Real-time early warning trigger log and external USGS earthquake feeds within 500 miles of Berkeley.
🟢 WARNING SEVERITIES
INFO: Minor micro-trigger or distant event. ADVISORY: Local vibration exceeding STA/LTA 6.5x. WARNING: Potential felt shaking (>M2.5 or PGA >0.02 m/s²). CRITICAL: Severe shaking (>M4.5).
⚡ USGS THEORETICAL ARRIVALS
Calculates exact P-wave (~6.0 km/s) and S-wave (~3.5 km/s) travel times through California crust to provide countdown seconds before shaking arrives.

ℹ️ WHAT IT MEASURES
Geospatial tracking of earthquakes within 700 miles on an interactive map showing Western North American active fault zones (San Andreas, Hayward, Cascadia Megathrust, Wasatch, Walker Lane).
🟢 REAL-TIME PROPAGATION
When an earthquake occurs, animated wavefront rings expand outward at P-wave speed (6.0 km/s) and S-wave speed (3.5 km/s) directly toward your home station in Berkeley.
⚡ WHAT TO LOOK FOR
Gold circle = USGS epicenter. Blue circle = P-wave (fast compression). Red circle = S-wave (damaging shear). Station marker shows arrival countdown timer.

Separates ambient seismic energy into 5 distinct environmental frequency bands to monitor local activity in the Berkeley neighborhood.
🟢 CAL STADIUM & GREEK THEATRE
Cal Stadium (100 yds): Crowd roar & stomping (2–5 Hz band).
Greek Theatre: Concert acoustic sub-bass coupling (25–45 Hz band).
⚡ TRAFFIC & INDOOR ACTIVITY
Trucks / Buses: 8–14 Hz rolling road vibration.

ℹ️ WHAT IT MEASURES
Real-time deep learning emulation computing instantaneous P-wave probability P(P) and S-wave probability P(S) curves on incoming waveform streams.
🟢 AUTOMATIC PICKS
When P(P) > 0.6, the engine flags a precise P-wave arrival timestamp T_P. When P(S) > 0.6, it records T_S.
⚡ WADATI DISTANCE CALCULATION
Using the arrival time difference (T_S - T_P), the engine derives epicentral distance: Distance ≈ 8.0 × (T_S - T_P) km.
ℹ️ WHAT IS THIS GRAPHIC?
This is a Power Spectral Density (PSD) chart. It breaks down the total vibration of your sensor into every individual frequency from 0.1 Hz (slow 10-second ground swell) up to 50 Hz (rapid 50-times-per-second tremors). The Y-axis measures energy power in decibels (dB).
🟢 WHAT THE RED & BLUE LINES MEAN
These are the USGS Peterson Global Noise Benchmarks. The Blue Line (NLNM) is the quietest deep underground mine on Earth; the Red Line (NHNM) is the maximum noise ceiling of busy cities. Being inside the shaded area means your station has healthy, normal background noise.
🌊 WHY DOES THE GREEN LINE MOVE?
The green line is your live sensor! It moves in real-time as the world breathes:
• 0.1–0.5 Hz (Left): Pacific Ocean surf swell hitting the Northern California coast.
• 0.5–10 Hz (Middle): Fault zone resonance & earthquake energy.
• 10–50 Hz (Right): Highway 24 traffic, trucks, and building AC vibrations.
🚨 WHAT TO WATCH FOR
Normal: Green line rests peacefully inside the corridor.
Footstep / Truck: Green line shoots above the Red line only at 15–30 Hz.
EARTHQUAKE: The green line surges above the Red line across ALL frequencies simultaneously!
ℹ️ WHAT IT MEASURES
Pitch-shifts and time-compresses inaudible infrasound seismic waves (1–10 Hz) into the human audible audio spectrum (50–1000 Hz).
🟢 WHAT YOU WILL HEAR
Quiet Ambient: A gentle deep resonant oceanic purr.
Heavy Truck: A low roaring growl passing from left to right.
Cal Stadium: A vibrating rumble.
⚡ EARTHQUAKE SONIFICATION
An earthquake sounds like a dramatic acoustic snap (sharp P-wave click) followed by a deep rolling thunderous explosion (S-wave rumble).
