How do you use triangulation to locate an earthquakes epicenter with three seismographs?
To locate an earthquake's epicenter using triangulation with three seismographs, first, each seismograph records the time it takes for seismic waves to reach it. By calculating the difference in arrival times of the primary (P) and secondary (S) waves, the distance from each seismograph to the epicenter can be determined. Each seismograph provides a circular area around it, with a radius equal to the calculated distance. The epicenter is located at the point where all three circles intersect.

What effect might an earthquake have on a river that runs perpendicular to the fault?
An earthquake can significantly affect a river running perpendicular to the fault by causing changes in its course and flow dynamics. The seismic activity may trigger landslides, altering the river's path, or create new channels due to sediment displacement. Additionally, ground shaking can lead to changes in the riverbed elevation, which could impact water levels and flow rates. These effects can result in flooding or drought conditions downstream, depending on the nature of the changes.
Why does earthquakes do so much damage to areas far away from its epicenter?
Earthquakes can cause significant damage far from their epicenter due to the propagation of seismic waves, which travel through the Earth's crust and can affect large areas. These waves, particularly surface waves, can lead to ground shaking, structural failures, and secondary effects such as tsunamis or landslides. Additionally, the intensity of shaking can vary depending on local geological conditions, such as soil composition and building structures, amplifying the impact even at considerable distances from the epicenter.
Does Hollywood have any natural disasters?
Hollywood itself does not experience natural disasters specific to its location, but the broader Los Angeles area is susceptible to several, including wildfires, earthquakes, and mudslides.

How many earthquakes occur in the sea every year?
Each year, thousands of underwater earthquakes occur, with estimates often exceeding 20,000. Most of these are minor and go unnoticed, as they are detected only by seismometers and do not pose a threat to land. The exact number can vary depending on geological activity, but the majority occur in tectonically active regions like mid-ocean ridges and subduction zones.
The seismogram from the strong earthquake will show a much larger amplitude and a more complex pattern of waves compared to the relatively weak earthquake, which will display smaller amplitude and simpler waveforms. The strong earthquake will produce pronounced P-waves and S-waves, while the weak earthquake may have less distinct waves. Additionally, the duration of the strong earthquake's seismogram will likely be longer due to the greater energy released. Overall, the contrast in the seismic signatures will clearly indicate the differences in their magnitudes and impacts.
How many people died in the nepal earthquake?
