The distance from the earthquake to the observation point is estimated using the arrival time difference of the P-wave and S-wave information needed to determine the distance from the focus of an earthquake to the seismic receiving station.
The distance from the epicenter of an earthquake to the seismic station is determined by the time difference between the first arrival of the P and S waves. This is known as the S-P interval.
Requires triangulation to determine the exact location. Three seismometers are required. A circle is drawn from each of the three different seismometer sites, with the radius of each circle equal to the distance from that seismic receiving station to the epicenter.

Answer:
Explanation below
Explanation:
Asia and the Pacific region have continued to remain the world's largest producer of fish. Various researchers have identified certain benefits of consuming seafood, which have caused greater demand for them. Apart from being ideal source of vitamins, fish is also rich in Omega 3 fatty acids, which can help prevent high blood pressure, cancer and heart diseases. Seafood also strengthen the immune system through their antioxidants.
Rapid advances in fishing technology have led to the dramatic increase over the last 50 years in how many fish we are able to catch. Most people in the fishing business now use factory ships, in place of fishing vessels. These ships are can stay at the sea for several weeks and they have all the necessary equipment that can be used to either freeze of tin fish that they catch using their hunting ships.
The factory ships need to get full before they can return to base and this has caused over a 7% growth in catches every year.
Answer:
lithosphere
The geosphere is considered to comprise the entire earth solid atmosphere. The earth is also into two parts the interior and the exterior core, the mantle and the crust.
