Hawaii Quake & Volcano Guide1.0.7 - App Store

Aloha!

This real-time earthquake & volcano monitoring app focuses on Hawaii Island’s three active volcanoes: Kilauea, the most active volcano in the world; Mauna Loa, the largest active volcano on Earth: Hualalai, perhaps the most mysterious volcano in Hawaii; the dormant volcano Mauna Kea & the possible next island Kamaehuakanaloa (Loihi)

Built for residents, researchers, educators, travelers, hikers, photographers, emergency planners, and anyone fascinated by Hawaii geology, Earthquakes Hawaii helps you move beyond headlines & see what's happening now.

Track the latest seismic activity with live USGS-based data:
- Live HVO cams for Kilauea, Mauna Loa, Mauna Kea, & Hawaii Volcanoes National Park
- Magnitude, depth, and location for each event
- Fast access to recent events across Hawaii Island & worldwide.

Big Island focus - 3 ways to explore the subsurface:
1. Cross-Section View
Vertical slices through the island show epicenters, hypocenters, & underground structures

2. Spinning Island View
Rotate slowly thru 360 view of Big Island & below to compare surface events, deeper quakes, & cross-sections from different angles.

3. 3D Point Cloud View
Explore using a fast (thanks to Apple Silicon) interactive 3D point cloud of earthquake activity below the island surface to see where events cluster in space and time

Visualization and analysis features:
- 3D globe with depth exaggeration and color-coded magnitude
- Adjustable time ranges including 24 hours, 7 days, and 30 days
- Large, resizable windows for close inspection on laptops & large displays. Perfect app to get the big picture of seismic & volcanic events on, around & below Big Island on big monitors
- Map view, search, useful stats, including counts, average magnitude, & max magnitude by time window
- Kilauea tilt data for additional eruption context
- Region filters for Hawaii, Big Island, Big Island plus Kamaehuakanaloa (Loihi), & worldwide activity

Custom Alerts:
A variety of free notifications can be set to help locals, researchers, photographers & volcano watchers stay aware of changing seismic & volcanic conditions. Swarm activity, tilt, lava flows, fountains, magnitude, depth & proximity, etc. offer clues to events.

Why people use Earthquakes Hawaii:
- Residents want fast local awareness
- Curious visitors want context before exploring the island
- Researchers & students want a clear visual tool
- Educators want a vivid way to explain Hawaiian volcanism
- 471 surprising FAQs about earthquakes, volcanoes, Hawaiian geology, and island history

Earthquakes Hawaii is also a great companion for anyone interested in lava, rift zones, calderas, earthquake swarms, volcanic tilt, magma movement, hotspot geology, & the birth of the Hawaiian Islands. It is a practical island tool, a geology viewer, & a living science window into one of the most active volcanic regions on Earth
Great for island life & field use:
- Check activity before hiking, sightseeing, camping, boating, diving, or visiting Volcano
- Watch earthquake sequences develop near Kilauea, Mauna Loa, or offshore south of Hawaii
- Compare shallow & deep events to better understand where activity is concentrated
- Timeline history of the volcanoes eruptions.
- Use the app as a daily volcano & earthquake dashboard for the Big Island

Whether you are a local keeping an eye on home, a visitor planning an unforgettable trip, or a researcher following seismic clues, Earthquakes Hawaii turns raw seismic data into a clearer, more visual, more useful experience

Built for research, education, exploration, travel, & the question almost everyone asks:
When will Kilauea erupt next?

This is only the beginning. More features are on the way

Version History Most important

* 3D Hypocenter Cloud can work with many more earthquakes simultaneously (Mac)
* Fixed freeze/beachball where the scene stopped rotating and the Map tab would hang
* Drag up now tilts the island toward you (Mac Y-axis was inverted)
* Orbit no longer accumulates weird roll - rotation stays predictable
* Reset View button on the bottom panel (expanded and collapsed) returns to the opening camera angle
* Much faster on M5 chips and Apple Silicon in general with large datasets: smarter clustering, background scene rebuild, hover/tooltip only on the quake under the cursor

Load larger historical earthquake files

* Help > Download & Load for Plum Amazing’s HistoricalQuakes.json (~8 MB) from your CDN; cached locally after first download
* Load from File shows real progress (reading MB > parsing > done), validates file type upfront, and disables controls while loading
* Loaded files no longer get silently replaced when you tap 24h / 7d / 30d
* All button shows every quake in a loaded file
* Time filters for loaded files anchor to the file’s newest event (not “right now”)
* Pill/menu shows the real filename (e.g. HistoricalQuakes.json)

Map & simulations stay responsive with thousands of quakes

* Fixed Map tab beachballing with large imports
* Map caps at 1,000 annotations (highest-magnitude events kept)
* 3D Cloud, Exaggerated Depth, and Cross-Section use adaptive clustering so dense feeds stay interactive

Clearer Live vs Historic data

* Data-source menu split into Live USGS Feeds and Historic (bundled, since 1900)
* Notable relabeled to Notable (live, last 30 days) for clarity
* Live/Historic badge and labels reflect what is actually on screen

Lifetime purchase option (iOS & Mac App Store)

* Paywall adds Lifetime Access ($14.99) alongside Daily and Monthly
* Layout updated to fit the lifetime option
* Buttons sized to match StoreKit controls

Mac window remembers size and position

* Restore window size and location after quit/relaunch

Also worth mentioning

* Cross-Section improvements
* Less clutter with large historical files: finer binning, small clusters render as individual dots
* Help explains slice thickness, xN cluster badges, and why vertical columns can be a grid artifact versus real geology

3D Cloud scope clarified

* Documented: 3D Cloud simulation currently shows Hawaii (textured Big Island) even when Region is Worldwide. Map and List still respect region. This app is mainly about Hawaii but can display events worldwide

Help & Guide expanded

* New sections: switching data sources, loaded-file behavior, cross-section slices, 3D Hawaii scope
* Historical Data card lists bundled datasets with availability checkmarks

Paywall polish

* Headline updated to “3 Options, Daily, Monthly or Lifetime”
* Policy divider moved; Restore button styling aligned with lifetime button color

Under the hood (mostly invisible)

* New QuakeDecimation engine shared across 3D, Depth, and Cross-Sectio)
* 3D scene builds on a background thread, then swaps atomically (smoother with 12k+ events)
* Mac window persistence uses AppKit autosave plus explicit UserDefaults backup

Latest Changes

* 3D Cloud map floor from MapKit snapshot, aligned with the 2D Big Island map
* Depth rods linking epicenter spheres to hypocenter cubes (toggle in panel)
* Epicenter spheres + hypocenter cubes with shaded faces
* Transparent ocean so rods aren’t blocked by a dark surface sheet
* Fixed north–south mirroring of quake positions vs the 2D map
* Unified quake dot sizes (Teeny→Large) across Map, 3D, Cross-Section, Spinning Island
* 3D panel depth rods on same row as dot-size picker (saves height)
* 3D min magnitude filter matches the 2D map
* Mac hover callout: Epicenter / Hypocenter, time, magnitude, depth
* App Store three-plan paywall (Monthly, Yearly, Lifetime) on iOS + Mac
* Lifetime IAP visible on iOS; shared checkout on Mac target
* App version update checker for Apple App Store notifies user of new versions. 1.0.7 May 25 1.0.6 Apr 30
