Seismology is an independent app. It is NOT affiliated with or endorsed by any government agency or public entity, and it does not officially represent one or provide government services. It only republishes data already published by the official agencies listed in full at the end of this description. Seismology brings together, in one app, earthquake reports from seven official seismological agencies — USGS, CSN, SSN, EMSC, GeoNet, JMA and SGC — plus tsunami bulletins from the three NOAA tsunami centers, and notifies you the moment an earthquake happens near you. And now, free: Family alerts, to know your family is OK after an earthquake. REAL-TIME INFORMATION Push notifications when an earthquake happens near you, based on the distance to the epicenter or the intensity estimated for your location. FAMILY ALERTS, FREE Create your family group and invite them on WhatsApp. If an earthquake is likely felt strongly where one of you is, the app asks them "Are you OK?" and tells the others; you can also tap "Ask my family" anytime. Everyone answers with one tap from the notification: "I'm OK" or "I need help". The whole family sees everyone's status on a board. Your family never sees your location. Requires signing in with Google, Apple or Microsoft. Not an emergency service. ON YOUR IPHONE The earthquake on your Lock Screen and in the Dynamic Island: how many felt it and how your family is doing. "Felt it" and "I'm OK" right there, from Control Center or with Siri. Widgets by location and for your family. INTERACTIVE MAP See all recent earthquakes on a map with markers sized by magnitude and colored by depth. Tap one for its magnitude, depth, time, distance from you and the agency's official report. COMMUNITY COMMENTS Post how you felt the quake and read what others in the area are reporting. FILTERS AND SEARCH Filter by agency, minimum magnitude and distance. Search earthquakes from the last 30 days, or the full history with Pro. PRIVACY No account is needed for the main features. Your location is used to show nearby earthquakes; for alerts, it is sent to our server, which decides which ones to send you. FREE, WITH OPTIONAL PRO The app and its main features are free. Seismology Pro, an optional subscription, adds alerts for several locations, the estimated intensity at your location, the full earthquake history and no ads. Seismology does not predict earthquakes and is not a replacement for official early-warning systems (ShakeAlert in the US, SASMEX in Mexico, JMA in Japan). It is an informational app showing events that have already occurred, as reported by the official agencies.

The quake meter is an app which uses the seismograph or seismometer in your phone to measure the strength of vibrations, tremors, earthquakes, and even the vibrations of the human body or any other objects around you. - High-Accuracy Seismometer: Detect vibrations from earthquakes to human movements with precision using your phone's built-in seismograph. - Seismic Wave Detection: Track seismic activities like earthquakes and volcanic eruptions using your phone’s accelerometer. - Detailed Graphical Analysis: Visualize seismic movements on graphs, displaying data across three dimensions for in-depth understanding. - Real-Time Mercalli Scale Readings: Get instant updates on ground motion intensity, with average and max values easily accessible. - Customizable MMI Chart: Tailor MMI charts to display seismic data over your chosen time frames for personalized insights. - Instant Alerts for Seismic Shocks: Stay informed with alerts on sudden accelerations or seismic events, keeping you prepared. - Effortless Data Autosave: Automatically save crucial seismic data in CSV format for detailed post-event analysis. - Comprehensive History Access: Review and share your seismic data history, complete with easily accessible CSV files. - Secure Cloud Storage: Safeguard your seismic data in the cloud, accessible on different devices via social accounts or email. - Apple Watch Compatibility: Seamlessly control your seismic measurements from your Apple Watch device, ensuring minimal interference. - Shareable Insights: Capture and share screenshots of your seismic findings with friends, spreading awareness and knowledge. Using the accelerometer in your phone, our app allows you to detect and record seismic waves generated by earthquakes, volcanic eruptions, avalanches and any other sources of seismic activity. Once the activity is measured, the graph feature presents a record of the ground motion at the point of measurement. Any ground movement or object is presented as a function of time along three Cartesian axes, with the z- axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface. During a span of measurement, you will track average and max values and see current corresponding Mercalli scale descriptions. You can set up your app to display current acceleration, XYZ or Mercalli scale values on the main screen. What’s more, you can find a second chart on the screen with MMI values which can be customized to display different lengths if you want to see shorter or longer time periods. The app allows you to take a screenshot of the whole view to share it with friends. The alerts feature notifies you about sudden acceleration changes or seismic shocks. Go to the settings screen and setup values you want to get notified after. Autosave allows you to save your data when shocks pass through the setup threshold. You can later view the saved CSV file to see the exact measurements during that time. The history screen allows you to see your saved data with date, time, avg, and max values along with a CSV file from the whole span of measurement. You can also share the data as you please. Keep your data safe with our cloud services, which allow you to create accounts and store your data.. Log in using your social media accounts or email to different devices to see and share your data. Our app comes with a brand new application for Apple Watch devices. You can easily control your measurements with your watch without having to touch your phone. Controlling the measurements with the watch avoids interference!
