Read the island in layers
Map, cross-section, and 3D hypocenter views show where quakes cluster beneath Hawaiʻi Island instead of flattening them into a list.
Hawaiʻi Volcanoes & Earthquakes for Mac
Your real-time dashboard view into the 3 active volcanoes, Kīlauea, Mauna Loa, Hualālai and the extinct volcano Mauna Kea. Live island wide HVO cams, alerts, maps and seismic ways to visualize the earthquakes.
Explore recent quakes by depth, region and history in map, list and 3D views built for people of all ages that want to learn more about Hawaiʻi.
A practical island guide for residents, visitors, students and anyone that wants to see the lava flow, feel the ground shake beneath them, avoid the tephera showers or watch a giant lava fountain.

Hawaiʻi Volcanoes & Earthquakes for Mac turns Hawaiʻi Island into a living dashboard. Follow Kīlauea, Mauna Loa, Hualālai, Maunakea, and Kamaʻehuakanaloa with live quake data, depth, history, observatory cams, alerts, and 3D views that reveal what is happening above the island and deep below it.

TimeRecent changes, alerts, swarms, history, and daily awareness.
One island. Many signals.
Quakes, volcano cams, activity context, and alerting come together in one fast visual tool.
Follow volcano signals, not rumors
HVO cameras, activity summaries, weather, tilt context, and dashboards help turn fast-changing Kīlauea and Mauna Loa conditions into something you can scan.
Know what changed today
Alerts for magnitude, depth, swarms, lava activity, and proximity give residents, visitors, teachers, and researchers practical awareness without doom-scrolling.
Map • Depth • 3D
See where swarms gather beneath Hawaiʻi Island.
Earthquakes are easier to understand when you can see how they stack beneath Hawaiʻi instead of reading them as isolated entries in a list. This app makes the island legible with a map view, cross-sections, and a rotating 3D point cloud that reveals the deeper geometry of swarms, rift activity, and offshore clusters.
It is built for the people who keep asking better questions: Where is activity concentrating? How deep is it? What changed in the last 24 hours? How does one area compare with another?
Built for island awareness
This is not just for geologists. It is for island life, field curiosity, education, and anyone who wants more context than generic earthquake alerts provide.
- Residents who want a fast daily read on local activity
- Visitors heading to Volcano, hikes, overlooks, and boat trips
- Educators and students teaching hotspot geology and island formation
- Researchers, photographers, and volcano watchers following swarms and eruption clues
Signals the app brings together
- Live HVO cams for Kīlauea, Mauna Loa, Maunakea, and Hawaiʻi Volcanoes National Park
- Cross-section view for hypocenters, depth, and underground structure
- Rotating 3D point cloud for spatial patterns below the surface
- Magnitude, depth, location, counts, averages, and max-magnitude stats
- Region filters for Hawaiʻi Island, Hawaiʻi Island plus Kamaʻehuakanaloa, and worldwide
- Hundreds of FAQs about Hawaiʻi earthquakes, volcanoes, geology, and island history
From Kīlauea context to daily island awareness
Use the app as a living local dashboard before hiking, visiting Volcano, teaching geology, photographing changing landscapes, or simply keeping an eye on what the island is doing now.
See eruption status, lava-flow context, live observatory notes, and quick-read activity summaries in one place.
Configure notifications for magnitude, depth, proximity, swarms, lava activity, and other changing conditions.
Pair seismic context with weather and volcano views so planning a visit feels grounded in real conditions.
A Hawaiʻi geology tool, not just another alert feed.
Hawaiʻi Volcanoes & Earthquakes for Mac is a practical island companion, a research viewer, and a visual answer to the question almost everyone asks sooner or later: what is happening under Hawaiʻi right now?
