Mw6.4 / 210km deep Earthquake in Afghanistan caught by GlobalQuake - Jan 11, 2024

Replay of an automatically detected earthquake in the GlobalQuake application. EMSC report: ==== What are the triangles? ==== Triangles represent seismic stations that are constantly monitoring ground movements at the certain location. At default, they have blue color and if any movement is detected, their color changes accordingly to the shaking intensity from green, yellow to red and they also flash to catch attention. ==== Why are some triangles upside down? ===== Seismic stations are divided into 3 main types in GlobalQuake based on which values they measure: accelerometers (upside down triangles) measure ground acceleration, seismometers (regular triangles) measure ground velocity and square stations measure ground displacement. ==== Why is the magnitude displayed in GlobalQuake different than from official sources? ==== GlobalQuake uses fully automatic earthquake parameters estimation system, which is completely independent on official sources. This means that information is sometimes provided faster, but can possibly be less accurate. ==== When will the next earthquake hit? ==== Earthquakes can strike at any time without any warning and nobody can predict when the next one is going to occur. Anyone who makes earthquake predictions is a scammer that abuses human fear and the fact that some locations are naturally more likely to experience earthquakes. ==== What is displayed when earthquake is detected? ==== Detected Earthquakes are shown as a cross with 2 colored circles spreading evenly from the epicenter. Blue color represents the predicted location of a so-called P-waves, which are weaker but much faster than S-waves, that are displayed as orange or red circles. You can read more about seismic waves here for example: If the program is not sure about the earthquake information, then a “?“ mark will be showed instead of cross in 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. ==== More FAQ ★ How do I install GlobalQuake? → Head to the GitHub repository at and follow the instructions there. All you need is to install Java version 17 or 21 and download latest version of Globalquake ★ What it the quality (S, A, B, C, D) ? → The quality expresses how much is GlobalQuake confident with 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 completely different spot that GlobalQuake is showing. ★ To be continued... ==== 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!
