# 🚀 Plugin Updates Summary - February 3, 2026

## 🎯 Summary

Today's work focused on **enhancing visual visibility and fixing animation issues** for the Lightning Detection and Earthquakes plugins. Both plugins now feature **highly visible colored circle markers** with custom icons, **magnitude/age-based sizing and colors**, **stable positioning** (no drift/movement), and **smooth animations for new events only**.

---

## 📡 Features

### **Lightning Detection Plugin v1.1.0** ⚡

#### Visual Enhancements
- **Colored Circle Markers**: Background color shows strike age (gold → orange → red → brown)
- **Lightning Bolt Icon**: White ⚡ emoji centered on colored circle
- **Size Range**: 12-32px based on strike intensity
- **High Visibility**: White 2px border + box shadow on all markers
- **Stable Positions**: Strikes remain at exact lat/lon coordinates (no movement)

#### Animation Improvements
- **Flash Animation**: New strikes flash with bright gold glow (0.8s)
- **Pulse Ring**: 30km expanding circle for new strikes (2s)
- **No Continuous Animation**: Old strikes remain static (no infinite pulsing)
- **First Load Fix**: No animation on initial plugin enable (only truly new strikes animate)

#### Technical Fixes
- Fixed infinite animation loop (all strikes were animating continuously)
- Fixed "dropping/sliding to the right" bug caused by changing IDs
- Implemented stable index-based seeded random for consistent strike positions
- Added rounded timestamps to IDs (10s intervals) for proper updates
- Increased z-index from 1000 → 10000 for visibility on all map layers

#### Statistics Panel
- Live dashboard showing strike counts (Fresh <1min, Recent <5min, Total 30min)
- Average intensity display
- Positive/Negative polarity breakdown
- Minimizable panel with persistent state (localStorage)
- Updates every 30 seconds

### **Earthquakes Plugin v1.2.0** 🌊

#### Visual Enhancements
- **Colored Circle Markers**: Background color shows magnitude severity (green → yellow → orange → red)
- **Seismograph Wave Icon**: Custom SVG with zigzag waves, epicenter dot, and ground impact triangle
- **Size Range**: 16-40px based on earthquake magnitude (M1-M7+)
- **Enhanced Color Gradient**: 7-color scale from light green (micro) to very dark red (great)
- **High Visibility**: White 2px border + box shadow on all markers
- **Stable Positions**: Earthquakes remain at exact coordinates (no movement)

#### Magnitude-Based Scaling
| Magnitude | Size | Color | Category |
|-----------|------|-------|----------|
| M1-2 | 16px | 🟢 Light Green | Micro |
| M2-3 | 20px | 🟡 Yellow | Minor |
| M3-4 | 24px | 🟠 Orange | Light |
| M4-5 | 28px | 🟠 Deep Orange | Moderate |
| M5-6 | 32px | 🔴 Red | Strong |
| M6-7 | 36px | 🔴 Dark Red | Major |
| M7+ | 40px | 🔴 Very Dark Red | Great |

#### Animation Improvements
- **Flash Animation**: New quakes flash with glow effect (0.8s)
- **Pulse Ring**: 50km expanding circle for new quakes (3s)
- **Shake Effect**: Removed (caused visibility issues)
- **No Continuous Animation**: Old quakes remain static
- **First Load Fix**: No animation on initial plugin enable

#### Data Feed Update
- **Previous**: `2.5_day.geojson` (M2.5+ from last 24 hours)
- **New**: `all_hour.geojson` (All quakes from last hour)
- More responsive to recent seismic activity
- Shows smaller quakes (M1.0+) for comprehensive monitoring
- 5-minute refresh interval

#### Technical Fixes
- Fixed infinite animation loop (all quakes were animating)
- Fixed icon visibility issues (markers were created but invisible)
- Removed CSS `transform: scale()` which caused coordinate issues
- Replaced with `brightness` and `drop-shadow` effects
- Increased z-index from 1000 → 10000 for visibility
- Changed from volcano emoji (🌋) to custom seismograph SVG

## 🔧 Technical Implementation

### Architecture

Both plugins follow the same enhanced pattern:

```javascript
// 1. Create colored circle with icon
const icon = L.divIcon({
  className: 'plugin-icon',
  html: `<div style="
    background-color: ${color}; 
    width: ${size}px; 
    height: ${size}px; 
    border-radius: 50%; 
    border: 2px solid white;
    box-shadow: 0 2px 8px rgba(0,0,0,0.5);
  ">${iconSVG}</div>`,
  iconSize: [size, size],
  iconAnchor: [size/2, size/2]
});

// 2. Create marker with high z-index
const marker = L.marker([lat, lon], { 
  icon, 
  opacity,
  zIndexOffset: 10000 // Always on top
});

// 3. Add to map first (before animation)
marker.addTo(map);

// 4. Animate only NEW events
if (isNew && !isFirstLoad) {
  setTimeout(() => {
    element.classList.add('animation-class');
    setTimeout(() => element.classList.remove('animation-class'), 800);
  }, 10);
}
```

### Data Flow

#### Lightning
```
generateSimulatedStrikes(50) 
  → Index-based seeded random (stable positions)
  → Add rounded timestamp to ID (10s intervals)
  → Age-based colors (gold → brown)
  → Create markers with zIndexOffset: 10000
  → Detect new IDs (previousStrikeIds tracking)
  → Animate only new strikes
  → Update stats panel every 30s
```

#### Earthquakes
```
fetch('all_hour.geojson') 
  → Parse USGS GeoJSON features
  → Extract magnitude, coordinates, properties
  → Magnitude-based sizing (16-40px) and colors (green → red)
  → Create markers with zIndexOffset: 10000
  → Detect new quake IDs (previousQuakeIds tracking)
  → Animate only new quakes
  → Refresh every 5 minutes
```

### Key Technical Solutions

1. **Visibility Issues**
   - Problem: Markers created but invisible
   - Solution: Added `zIndexOffset: 10000` + CSS z-index 10000 !important
   - Result: Icons always appear on top of all map layers

2. **Animation Drift**
   - Problem: CSS `transform: scale()` caused markers to move/slide
   - Solution: Removed transform, used `brightness` and `drop-shadow` instead
   - Result: Markers stay at exact coordinates while animating

3. **Infinite Animation Loop**
   - Problem: All markers animating continuously (CSS infinite animation)
   - Solution: Removed infinite CSS animations, apply temporary class only to new events
   - Result: Only new events animate once, then become static

4. **First Load Animation Spam**
   - Problem: All markers animate on initial enable (no previousIds yet)
   - Solution: Added `isFirstLoad` ref flag, skip animation on first data load
   - Result: Smooth enable with no false positives

5. **Lightning Position Drift**
   - Problem: Simulated strikes moved every minute (seed based on time)
   - Solution: Changed to index-based seed + rounded timestamps in ID
   - Result: Each strike stays at same location, IDs change to show updates

6. **WSPR Console Spam**
   - Problem: Thousands of "[WSPR] Plugin disabled" messages
   - Solution: Added guard to check if controls exist before cleanup
   - Result: Clean console with no spam

## 🎨 User Experience

### Visual Improvements

**Before:**
- Transparent emoji icons (🌋 ⚡) with just text color
- Hard to see on map backgrounds
- Icons moved/drifted across screen
- All markers animated continuously
- Confusing on first load (everything flashing)

**After:**
- Solid colored circles with white icons/SVG
- Highly visible on all backgrounds
- Icons stay at exact positions (stable)
- Only new events animate once
- Clean first load (no false animations)
- Professional appearance with borders and shadows

### Animation Behavior

| Event | Before | After |
|-------|--------|-------|
| Plugin Enable | All markers animate | Static markers appear |
| New Event | Hard to identify | Bright flash + pulse ring |
| Data Refresh | All markers re-animate | Only new events animate |
| Old Events | Continuous pulsing | Static (no animation) |

### Size & Color Scaling

**Lightning (Age-Based):**
- Fresh strikes: Large, bright gold circles
- Aging strikes: Gradually smaller, darker colors
- Old strikes: Small brown circles (fade out)

**Earthquakes (Magnitude-Based):**
- Micro quakes (M1-2): Small green circles
- Minor quakes (M2-3): Medium yellow circles
- Moderate quakes (M4-5): Larger orange circles
- Major quakes (M6-7): Very large dark red circles
- Great quakes (M7+): Maximum size, darkest red
