Earthquake Maps vs PhosphorHertz

eQuake is a modern earthquake tracking app built to make seismic activity easier to follow, easier to understand, and more meaningful at a glance. With a live map, detailed event views, and advanced filtering tools, eQuake helps you follow recent seismic activity with greater clarity and explore events in a more informed way. It does more than display data. It turns seismic information into a cleaner, more readable, and more refined experience. Highlights - Live earthquake and seismic event map - Detailed event information - Filter by magnitude - Filter by date range - Filter by event type - Quickly center the map on your location - View your distance to an earthquake - View your distance to the nearest fault line - Instantly see last update time and event count One of eQuake's standout strengths is its multi-source data approach and advanced map visualizations. The app combines earthquake data from both USGS and EMSC, then refines it with its own merge logic to create a cleaner, more balanced, and more consistent event stream. This helps handle duplicate records more intelligently and delivers a more polished tracking experience. Advanced Map Layers - Active Fault Layer for viewing seismic activity in a richer geological context - Scatter Plot view for reading event distribution with greater clarity - Heat Map view for spotting regional intensity patterns at a glance - Mag Heat view for interpreting density and magnitude impact together eQuake presents earthquake data through a more refined visual language, making it easier to track recent seismic movement, explore events in greater depth, and follow multi-source data through a more elevated experience.

PhosphorHz is a real-time HF radio propagation monitor for amateur radio operators. It pulls live space weather data from NOAA's Space Weather Prediction Center and translates it into band-by-band conditions you can act on — right now, from your location. No guesswork. No stale forecasts. Just the numbers, rendered in a retro CRT phosphor display that would look at home in a Cold War listening post. BAND CONDITIONS See at a glance which HF bands are open, marginal, closed, or blacked out. Conditions are calculated from real-time solar flux, geomagnetic activity, and X-ray flux data — not generic regional forecasts. Each band shows your local status plus path-specific conditions to every DX target you configure. MUF CALCULATION The Maximum Usable Frequency for a 3000km reference path from your QTH, derived from Solar Flux Index, solar zenith angle, and depressed by geomagnetic activity. Individual MUFs are calculated for each great-circle path to your DX targets, because the ionosphere doesn't care about averages. SOLAR INDICES All the numbers that matter, updated in real time: Solar Flux Index (SFI) with 30-day trend chart Planetary Kp Index with 24-hour bar chart Estimated Sunspot Number (SSN) GOES X-ray flux class and latest flare detection Solar wind IMF Bz component NOAA R/S/G scales (Radio Blackout, Solar Radiation, Geomagnetic Storm) Running A-index and solar wind Bt Each index includes a plain-language assessment: is the F2 layer well ionised? Is the geomagnetic field quiet or disturbed? Is the solar wind coupling or shielded? 3D GREYLINE GLOBE A SceneKit globe shows the solar terminator — the boundary between day and night — in real time. The greyline (twilight zone along the terminator) is where lower-band DX propagation is enhanced, and it's rendered as an amber band you can see at a glance. The globe displays coastlines, your QTH position, DX target locations, and great-circle paths coloured by band condition. Drag to rotate. Double-tap to recentre on your station. Hit play to watch the Earth spin. SPACE WEATHER ALERTS NOAA SWPC alerts and warnings filtered for HF relevance. Flare events, geomagnetic storms, radio blackouts — the alerts that actually affect your ability to make contacts, with full detail on tap. DX TARGETS Configure up to five target regions. PhosphorHz calculates path-specific propagation for each one, using great-circle geometry and the MUF at the midpoint of each path. What's open to Japan might be closed to South America — and now you can see both at once. FEATURES Real-time data from NOAA SWPC (public domain, no API key required) Band conditions for 160m through 6m Path-specific propagation to multiple DX targets 3D interactive greyline globe with terminator visualisation Sunrise/sunset times and countdown to next solar event Day/night/greyline status at your QTH Kp index 24-hour bar chart SFI 30-day trend line Full space weather alert log with 30-day history Maidenhead grid locator display Automatic location detection or manual grid entry Green phosphor and amber phosphor CRT themes CRT scanline overlay effect Designed for iPhone, portrait orientation No ads.
