📜 QuakeViewer3D Release Notes

v1.3.0 (Latest) 2026-08-28

🗺️ Real-Time Seismic Intensity Observation Map, Global Attenuation Engine & International MMI (v1.3.0)

JMA Live Station Plotting (Live Feed): Real-time integration with P2P Quake API (Code 551) to plot verified observation point intensities (1 to 7) across ~1,800 Japanese municipalities with official glowing 3D spheres.
Global Ground Motion Attenuation Engine: Integrated Si & Midorikawa (1999) and USGS GMPE attenuation formulas to compute real-time intensity and PGA across worldwide cities and radial mesh grids for international earthquakes.
Dynamic International MMI Localization: Automatically switches to Roman numeral Modified Mercalli Intensity scale (II to X+, e.g. MMI VI: Strong) for English and global users for effortless comprehension.
Multi-Layer Penetration Picking (drillPick) & UI Hardening: Ensures seamless camera flyTo navigation even through overlapping intensity bubbles and shockwaves across all 14 language portals.

v1.2.0 2026-08-24

🛡️ Security Hardening, Full 14-Language Sync & SatViewer3D Integration (v1.2.0)

🛡️ Multi-Layer Security & Cloudflare Headers: Implemented comprehensive XSS/SSRF input sanitization and strict security headers (anti-clickjacking, nosniff, referrer-policy).
🌐 Full 14-Language Sync for Live Status & Quake Details: Perfectly localized live auto-update status badges, tsunami threat analysis, and intensity scales across all 14 languages.
🛰️ Sister Service "SatViewer3D" Bi-Directional Integration: Added direct companion links and unified official contact support ([email protected]).
