The Science Fair<\/strong> <\/a>is the largest popular science event organized by the Czech Academy of Sciences since 2015. The event took place at the PVA Expo Prague Let\u0148any from Thursday, June 5, to Saturday, June 7, 2025. Admission was free. Over 100 exhibits were on display, including 40 from the Czech Academy of Sciences’ research institutes, universities, and other scientific institutions and companies. This year, the three-day event attracted over 58,000 visitors.<\/p>\nWe sincerely thank everyone who actively contributed to the preparation of the exhibit and who were available to visitors at the Institute of Geophysics (GF\u00da) booth during the event.<\/p>\n
Our exhibit was titled “Dynamic Planet Earth \u2013 A Journey to the Depths”<\/strong> and was divided into several stations focused on seismology.<\/p>\n
\nCreate Your Own Earthquake<\/strong> \u2013 During an earthquake, you can feel the ground moving beneath your feet, buildings shaking, and often hear a rumbling sound. Earthquakes are measured using seismometers. Visitors could try stomping on the ground to see how these sensitive instruments work.<\/p>\n
\nShake Table<\/strong> (also known as a seismic vibration table) \u2013 This device is used in research and engineering to simulate the effects of earthquakes on various structures. The table replicates the movements occurring during real earthquakes, enabling testing and evaluation of the resilience of buildings, bridges, infrastructure, and other structures to seismic waves. Children and adults could build their own structures and test whether they would withstand earthquake waves.<\/p>\n
\nEarth Projection<\/strong> \u2013 On a circular screen, we projected how seismic waves travel around the globe, where earthquakes most frequently occur, and what the Earth’s interior looks like\u2014from the crust to the core. Viewers could see animations of mass movements within the Earth’s mantle and the structure of the entire Earth.<\/p>\n
\nWave Propagation Animations<\/strong> \u2013 On a monitor, we showed how waves from major recent earthquakes spread across Europe, recorded by stations from the AdriaArray project. These included earthquakes in Morocco (2023), Turkey (2023), Myanmar (2025), and Slovakia (2024).<\/p>\n
\nSeismic Experiments<\/strong> \u2013 At this station, we demonstrated how different types of seismic waves propagate and how they can be recorded using standard mobile phone applications. We simulated earthquakes using a manually operated vibration table that can be easily built at home. We also demonstrated the effect of waves of different frequencies on buildings of different heights (resonance test) and possible methods of isolation. Additionally, we showed the effect of liquefaction of sediments during earthquakes.<\/p>\n
\nBanging Map<\/strong> \u2013 Here we simulated determining the location of an earthquake. The map featured five sensors (stations) that recorded the arrival time of waves generated by striking the map with a hammer. A connected display showed waveforms from all the sensors and the calculated position of the strike on the map.<\/p>\n
\nBuild Your Own Seismograph<\/strong> \u2013 Visitors could assemble a simple horizontal seismograph from prepared parts and take home a seismogram recorded on paper.<\/p>\n
\nMemory Game<\/strong> \u2013 On a touch panel, visitors could play a memory game (pexeso) with historical depictions of earthquakes and volcanoes.<\/p>\n
