SOURCE-AWARE BY DESIGN
One earthquake. Seven source perspectives.
QuakeSense brings together USGS, EMSC, GFZ/GEOFON, GDACS, ISC, GeoNet, and BMKG. It reconciles likely duplicates into a local event while retaining provider identity, updates, revisions, and source provenance. Partial provider failures remain visible instead of being presented as a complete refresh.
Agreement and value ranges
Compare source count, magnitude, depth, location, confidence, and disagreement.
Revision and status history
Preserve preliminary, reviewed, deleted, and superseded observations over time.
Offline and provider states
See cached information, partial refreshes, and provider-health context honestly.
FROM GLOBAL ACTIVITY TO YOUR PLACES
See what happened, what changed, and what it may mean near you.
Now, History, and Map
Switch between My Area, Country, and Global views. Review 24 hours to 30 days of activity, sort history, and explore magnitude-aware clusters on OpenStreetMap.
Personal impact context
Open an event for approximate distance and direction, depth, local and UTC time, source agreement, and an estimated shaking/MMI band with confidence and uncertainty.
Smart Place Profiles
Create Home, Work, Family, Custom, or time-limited Travel Watch profiles with radius, magnitude, MMI, quiet-hours, and critical-override preferences.
Alert Readiness
Check notification permission, channel state, selected place or location, recent source refresh, worker heartbeat, battery restrictions, full-screen eligibility, and other local alert conditions.
Alerts depend on upstream data, network access, Android scheduling, permissions, battery policy, and your settings. QuakeSense does not guarantee immediate delivery.
PREPARE · DURING · AFTER
Preparedness tools for before the shaking starts.
Work through a preparedness checklist, review Drop, Cover, and Hold On guidance, use read-aloud support, keep emergency contacts, follow post-quake checks, and share an explicit “I’m Safe” update.
- Checklist and preparedness score
- Read-aloud protective guidance
- Emergency contacts and post-quake checks
- Family places and user-initiated check-ins
QuakeSense never automatically calls emergency services. Calls and check-ins remain user initiated.
LOCAL-FIRST PRIVACY
Sensitive context stays on your device by default.
The reviewed app requires no mandatory account and contains no behavioral advertising SDK. Private places, household topology, motion samples, health signals, structural images, and local evidence are processed or stored locally unless you explicitly export or send a narrowly scoped item.
- ACCOUNTNo mandatory account or cloud sign-in
- PAYWALLNo ads, subscriptions, purchases, or paywalls in the reviewed source
- LOCATIONNo ACCESS_BACKGROUND_LOCATION permission on the phone
- STORAGEPrecise places, images, evidence, and credentials use local or encrypted app-private storage where applicable
- MOTIONRaw watch motion is transient and not retained or sent by default
- EXPORTExports are explicit, minimized, and redacted where supported
BUILT FOR MORE THAN ONE SCREEN
Phone, tablet, foldable, widgets, and Wear OS.
Four complete interface styles
Choose Flagship, Classic, Original, or Simple. Wider layouts can use navigation rails and dual-pane event views, while foldable layouts avoid the hinge area.
Language distinction: this website offers 31 page variants. The reviewed phone build separately declares 36 locale tags; availability and translation completeness can vary.
Two cache-backed widgets
Near Me and Significant Activity widgets read the local cache for fast home-screen context without creating a second monitoring engine.
Signed context on your wrist
The standalone Wear OS app can fetch signed normalized bulletins over watch networking and can also receive phone synchronization. Use the Seismic Dial, Near Me Tile, watch-face complication, event details, phone handoff, and an “I’m Safe” check-in.
Wear features depend on the watch, sensors, radios, network, permissions, and OEM background behavior. Wave-arrival and proximity output are broad estimates, not guaranteed countdowns or rescue range.
ADVANCED · OPT-IN · CAPABILITY-CHECKED
Local tools for verification, research, automation, and disrupted connectivity.
Advanced tools are optional. They explain permission and battery costs, check device capability at runtime, and are designed to degrade safely when hardware or services are unavailable.
VERIFY / RESEARCH Trace evidence and explore seismic data
- 16 · Provenance Time MachineReplays immutable source observations, revisions, differences, and redacted exports.
- 18 · Evidence VaultBuilds a signed, tamper-evident local ledger with independently verifiable exports.
- 19 · Pocket Seismology WorkbenchExplores selected station waveforms with visible, resettable processing parameters.
- 17 · GMPE & Soil LabShows versioned exploratory ground-motion distributions with uncertainty and site context.
- 20 · QuakeQLRuns bounded, allowlisted local rules and backtests—without scripts or remote plug-ins.
Limit: the on-device GMPE engine works in Android Kotlin but was not yet packaged as Kotlin Multiplatform or Rust/NDK. Research output is exploratory and cannot override official policy.
REVERSIBLE AUTOMATION Stage, verify, test, then act locally
- 6 · QuakeScript BusPublishes signed, expiring real/drill/test envelopes to configured local consumers.
- 7 · Two-Phase InterlockStages idempotent PREPARE, COMMIT, and CANCEL transitions after source checks.
- 10 · Chaos LabExercises rules and adapters with isolated scenarios, virtual time, and readiness reports.
- 8 · Hue Evacuation WaveGuides approved routes with reversible, bridge-local light sequences and fallbacks.
- 9 · Home Digital-Twin DiffCompares encrypted Home Assistant snapshots and separates changed, stale, and normal states.
Limit: automation is reversible by default. Locks, garage doors, gas, electrical systems, elevators, and other high-consequence actuators remain blocked unless a certified external controller owns the real interlock. Home Assistant support exists; production Google Home integration was not implemented in the reviewed version.
OFFLINE RESILIENCE Carry small, explicit rescue context
- 11 · Delay-Tolerant Rescue CapsulesStore and forward encrypted, expiring assistance messages without relaying earthquake warnings.
- 12 · NFC Rescue PassportWrites user-approved public details plus a signed encrypted record to compatible media.
- 13 · Rubble BreadcrumbRecords an explicitly started approximate inertial trail with drift and uncertainty shown.
- 14 · Acoustic Through-Rubble ModemRuns a visible, user-initiated low-rate audible send/receive session with decode confidence.
- 15 · Structural Change ComparatorCompares repeatable surface captures for visual change without judging structural safety.
Limit: the acoustic modem is audible, not ultrasonic, and representative field validation was incomplete. The structural comparator reports only “visual change detected” or “not reliably compared”; it never labels a building safe or unsafe.
COMPATIBLE WATCH Haptics, check-ins, and beacon fallbacks
- 1 · Haptic Wavefront ClockProvides broad, uncertainty-labelled arrival and intensity bands through compatible haptics.
- 2 · Safe-Route HapticsFollows signed, expiring prepared-route packs with eyes-free waypoint cues.
- 3 · Gesture TriageUses explicit-session on-device gesture inference with read-back and cancellation.
- 4 · Entrapment SentinelSends an unverified assistance summary only after arming and a cancellation window.
- 5 · Rotating Rubble BeaconAdvertises short-lived BLE rescue identifiers with network, haptic, or audible fallbacks.
Limit: availability varies by watch hardware and permissions. Entrapment and gesture messages are unverified signals, range is not guaranteed, and the app never automatically calls emergency services.

- It does not predict earthquakes or replace official warning systems.
- It does not guarantee alert delivery, arrival time, intensity, route position, radio range, or rescue outcome.
- It does not automatically call emergency services.
- It does not provide a structural-safety verdict.
- It does not continuously track phone location in the background.
- Hardware, radios, sensors, health access, bridges, brokers, and upstream providers vary by device and configuration.
- The reviewed release had working Home Assistant paths but no production Google Home adapter.
- The reviewed audible modem lacked a representative field-validation matrix.
- The reviewed release had no recorded physical Wear OS watch validation.
CLEAR ANSWERS
Frequently asked questions.
Is QuakeSense an official earthquake-warning service?
No. QuakeSense is an informational and preparedness companion built on public seismic data. Follow alerts and instructions from your local authorities.
Does QuakeSense predict earthquakes?
No. It reports and reconciles published seismic observations and calculates local estimates with stated uncertainty.
Do I need an account?
No mandatory account or cloud sign-in exists in the reviewed app.
How does QuakeSense use location?
Location supports My Area, selected places, distance, impact context, and explicit route or rescue tools. The phone app does not request background-location permission. An explicit nearby provider query may send its coordinates directly to USGS or EMSC.
Can QuakeSense call emergency services for me?
No. Emergency calls, check-ins, and messages remain user initiated. Advanced assistance signals are labelled unverified.
Does it work without the phone on Wear OS?
The standalone Wear app can use watch networking for signed bulletins and can also synchronize with a paired phone. Individual features still depend on the watch’s hardware, permissions, network, and OEM behavior.
Is QuakeSense free?
The reviewed source contains no ads, in-app purchases, subscriptions, or paywalls.
