THey know most of the times. They don't know it when it happpens so suddenly, etc.
Scientists use instruments called seismometers to detect and record seismic waves emitted by earthquakes. By analyzing the timing and intensity of these waves at different monitoring stations, scientists can triangulate the epicenter of the earthquake and determine its exact location.
Scientists in Haiti knew that an earthquake was inevitable due to the country being located along the boundary of the Caribbean and North American tectonic plates, which were building up stress over time. This tension was released in the form of a devastating earthquake on January 12, 2010, with a magnitude of 7.0.
Scientists use seismic waves to find an earthquake epicenter. By analyzing the arrival times of primary (P) and secondary (S) seismic waves at different seismic stations, scientists can triangulate the epicenter of the earthquake.
Scientists compare earthquake magnitudes using the Richter scale or the moment magnitude scale to understand the differences in seismic activity. These scales measure the energy released by an earthquake, with higher numbers indicating stronger earthquakes. By analyzing these measurements, scientists can determine the severity and impact of earthquakes.
Earthquakes are unpredictable and can happen at any time. However, it is impossible to know exactly when or where the next earthquake will occur. It is important to be prepared and follow safety precautions in earthquake-prone areas.
Probably not, but they did know that japan is on the ring of fire (the border between two plates) so earthquakes are more likely to happen.
The Benefits of knowing when an earthquake is going to happen is that scientists can warn everyone in advance.
Seismographs
California sits an a variety of fault lines and it is only a matter of when, not if, a big earthquake will occur. Scientists say it's a certainty. They just don't know the exact time it will happen.
There will, no doubt, be an earthquake in 2012 but no one can know when or where it will happen, or how severe it will be.
Scientists use instruments called seismometers to detect and record seismic waves emitted by earthquakes. By analyzing the timing and intensity of these waves at different monitoring stations, scientists can triangulate the epicenter of the earthquake and determine its exact location.
We do not know. Earthquakes are not predictable.
hey think about it do you think scientists always know what's going to happen in the future? i dont think so so stop asking these kinda stupid questions
Earthquakes happen when the Earth's crust shifts violently. So if we know that an earthquake has happened in California, then scientist know that the crust under California is unstable, therefore making earthquakes more likely to happen there. Earthquakes can happen anywhere, but the tend to happen repeatedly in certain spots
By the way earthquake waves refract as they pass through it.
This earthquake happen in januray 22,2009
a earthquake happens whaen a plate moves that what happen when we had the christchurch earthquake happened.
