GEOLOGY

Detailed explanation-1: -What resources do scientists use to predict when and where future catastrophic events may occur? Scientists map historic catastrophic events caused by natural processes to help predict future events. They also use current technology such as weather tracking technology, doppler radar, etc. to collect data.

Detailed explanation-2: -Terrain models (3D digital representations of the Earth’s surface) are important for predicting potential disaster scenarios. Without terrain models, we can’t know where it might flood, how severe a landslide might be, or how quickly an avalanche can move.

Detailed explanation-3: -Satellites give weather scientists a “big picture” overview of weather development, which is useful in storm tracking. Tornadoes, however, are trickier to predict since they are much faster-moving events; meteorologists use Doppler radar to measure moving objects such as hail or rain within developing supercell clouds.

Detailed explanation-4: -Seismic sensors (seismometers) and vibration sensors (seismoscopes) are used to monitor for earthquakes (and downstream tsunamis). Radar maps are used to detect the signature “hook echo” of a tornado (i.e., a hook that extends from the radar echo). More items •11-Nov-2019
