==== What are the colored circles? ====

Circles represent seismic stations that are constantly monitoring ground movements at a certain location. At default, they have a blue color and if any movement is detected, their color changes according to the shaking intensity from green, yellow to red and they also flash to catch attention.

==== Why is the magnitude displayed in GlobalQuake different from that of official sources? ====
GlobalQuake uses a fully automatic estimation system for earthquake parameters, which is completely independent of official sources. This means that information is sometimes provided faster, but can possibly be less accurate.

==== When will the next earthquake hit? ====

Earthquakes are unpredictable events that can occur without prior notice. It is important to understand that current scientific knowledge does not allow for precise prediction of earthquake occurrences. Individuals claiming to predict earthquakes should be approached with caution.

==== What is displayed when an earthquake is detected? ====

Detected Earthquakes are shown as a cross with 2 colored circles spreading evenly from the epicenter. The blue color represents the predicted location of so-called P-waves, which are weaker but much faster than S-waves, which are displayed as orange or red circles. You can read more about seismic waves here for example: https://www.sciencelearn.org.nz/resou...

If the program is unsure about the earthquake information, a "?" will be shown instead of a X at the epicenter.

Old earthquakes are displayed as smaller circles with their radius proportional to the estimated magnitude and their color depends on their depth, magnitude, or age, depending on the current settings.

If the earthquake is estimated to be strong enough that it might be felt at some location, a colored hexagonal overlay will be shown according to the estimated intensity in MMI scale. https://en.wikipedia.org/wiki/Modifie...

==== More FAQ ====

★ How do I install GlobalQuake?
→ Head to the official GlobalQuake website at https://globalquake.net/download and follow the instructions there. All you need is to install Java version 17 or 21 and download the latest version of GlobalQuake

★ What is the quality (S, A, B, C, D)?
→ The quality expresses how confident GlobalQuake is about the earthquake it has detected. If the quality is high (S, A), then the earthquake is very likely detected at the correct location with the right depth and reasonably close magnitude. Quality of C or D likely means that the detection isn't very accurate and the actual earthquake might be at a completely different spot than GlobalQuake is showing.

★ What magnitude type is used?
→ GlobalQuake uses its own magnitude formulas that were made to best fit official readings. Therefore, the magnitude is neither mB, Mw, or anything like that. We simply call it "GlobalQuake magnitude" or Mgq.

==== DISCLAIMER ====

Do not use GlobalQuake as Your primary way of receiving Earthquake Early Warnings!!
There is no guarantee that the application will display the appropriate warning in case of a severe earthquake in your area!

Please keep in mind that we are not seismologists nor scientists and everything is made out of pure enthusiasm and based on long-term experience with observing earthquakes.
