About this app

Explore earthquakes. Keep the evidence.

Seismica brings the USGS earthquake catalog to iPhone, iPad and Mac. Find events in a region, inspect their details, and save a study you can return to later.

SEARCH THE AREA THAT MATTERS

Browse a world map with earthquake markers and active fault lines. Search for a place, use the map's current view, or choose a center and radius. Filter by magnitude, explore the past day, week or 30 days, or select a historical date range.

UNDERSTAND EACH EVENT

See the reported magnitude and its scale, depth, coordinates, origin time and review status. Compare local time with UTC and check when the catalog record was updated. Read available shaking-intensity information, then open the full USGS report inside the app.

SAVE A STUDY

Save an event or a named search with a frozen copy of its records.…

App Store

Version 1.2 · 2026-09-20
• Search using the current map area, a place name, or a center and radius. • Save events and named searches with frozen records you can reopen offline. • Export CSV and GeoJSON with source and retrieval details, and import Seismica GeoJSON studies. • Inspect native event details with magnitude types, UTC time, review status and available intensity data. • More reliable date-range searches, visible refresh errors and clear result limits. • Map preferences and zoom are preserved, and revised catalog records update on the map.

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
