Earthquake 3D Animation
Earthquake 3D is a powerful new way to visualize Earthquake information. The app has several Earth display types and includes an Atlas database with over 4000 years of Historic Earthquake information. Individual quake indicator ‘flags’ can be clicked to show detailed information.
Earthquake simulations show how 16 hazard locations could be affected by a Northridge-sized earthquake. This information will improve risk assessment and help protect lives and property.
The magnitude of an earthquake is a measure of the size of the seismic waves created by the event. These waves move through the Earth and are detected by seismographs, satellites, tide gauges, and other instruments. The greater the magnitude, the more energy is produced and the greater the damage caused.
The Japan quake, for example, was a magnitude 9.0 event that generated tsunamis and nuclear crises. Scientists say they could use 3D animations to communicate these temblors more effectively than traditional methods such as peaks on a seismograph or maps overlain with locations and magnitudes of temblors.
This virtual exhibit uses 3D animations to show 16 potential Northridge-sized earthquakes around Southern California. Each animation highlights the likely source fault and shows a ShakeMap of expected shaking levels. The animations also display the expected population losses from each potential earthquake.
The distance of an earthquake can be determined by comparing the speed of P- and S-waves at different seismographs. The distance can also be estimated from the amplitudes of recorded ground motion, but this method requires knowing the location of the epicenter.
A common technique used in the past is to draw circles on a map with radii equal to the difference in arrival times of P and S waves at each seismograph. Ideally, the three circles should intersect at one point, indicating the location of the earthquake.
The Earthquake 3D app allows users to easily triangulate an earthquake using data from 3 or more seismic stations. The app shows the locations of the station on a world map and enables users to easily adjust the circle size. After the station locations are close to each other, the app shows a marker at the intersection point, displaying the latitude and longitude of the epicenter. The app can also be used to visualize Plate Tectonic movement in an easy-to-understand way.
Earthquake 3D is a simple program that gives you a look at the most recent earthquakes in your area. It can also filter the earthquakes by their magnitude and age. The app also allows you to zoom in and out of the 3D model.
The application has an intuitive interface and is easy to use. It also supports multiple users at the same time. The application can even work on a Mac computer.
This video visualizes the locations of all recorded earthquakes over a 15-year period. Each quake appears as a colored circle and its size and color correspond to the earthquake’s magnitude. The visualization is then filtered to show only those earthquakes with magnitudes greater than 6.5, which are known to create tsunamis.
John Carmack’s Quake engine used run-length encoding to prevent the rendering process from calculating all the space outside the player’s view, which greatly reduced its computational load. This method allowed the game to be played on computers with very little memory capacity.
An earthquake simulation can be used to sensitize people against damage caused by an earthquake or for training participants for rescue missions. A realistic simulation requires accurate modeling of the motion response of the objects and their environment. This is done by using a combination of non-linear structural numerical analysis and heuristic based estimation techniques. After an appropriate time history response has been determined, a 3D computer model is created. This model can be mapped with crack, damage and collapse effects on the basis of the characteristic parameters estimated earlier.
The path of the observer/camera assembly in the earthquake scenario is decided based on the purpose of the simulation. This could be either a fixed predetermined path or it could be a real-time process. The movement of the camera assembly is adjusted according to the earthquake motion response at different points on that path. This is achieved by incorporating the base motion data at those points into the model of the object.
