Bellwork Answer Bank (1 will be used twice) 31 Richter scale Mercalli Scale Small Fault earthquake 1. The ______ ______ is a measure of the actual energy released from an earthquake 2. The ________ intensity scale is a way of measuring earthquakes based on eyewitness and damage reports. 3.The point or location directly above an earthquake’s focus is called the ________ 4. _____ waves are the fastest and are recorded first. 5. _____ waves are slower than p-wave and are recorded second. 6. An earthquake with a Richter magnitude of 6.0 releases ________ times more energy than a 5.0 earthquake

Bellwork Answer Bank (1 will be used twice) Richter scale Mercalli Scale Small felt 62 San Andreas What is the name of the fault we have here in California where major earthquakes are produced? 2. The ______ ______ is a measure of the actual energy released from an earthquake 3. Earthquakes with magnitudes________ usually are not _______. 4. Earthquakes with magnitude _______ can cause severe damage.

Bellwork 1.The_____ is the point in the earth’s interior where earthquake energy is released. 2.The _______ is the point or location directly above an earthquake’s focus. 3.The three types of seismic waves are_____, _____, and _____. 4.______ waves are always recorded first and ______ are always recorded second. 5. What do we call the time delay between the P and S wave? 6. Please Draw and label:

Bellwork Station ____ is located farther from the epicenter because it has a _____ S-P time delay. Station is _____ is located closer to the epicenter because it has a ______ S-P time delay interval 3) The Mercalli and Richter scales can both be used to measure earthquake ________. 4) An earthquake with a Richter magnitude of 5.0 releases _____ times more energy than a 7.0 earthquake. Answer Bank 62 liquid A S-waves magnitude B shorter farther

Bellwork Answer Bank 14 minutes 11 minutes 10 minutes 7 minutes 21 minutes 22 minutes 1. About how long did it take for the first P-waves to reach station A? 2. About how long did it take for the first S-waves to reach station A? 3. About how long did it take for the first P-waves to reach station B? 4. About how long did it take for the first S-waves to reach station B?

Bellwork The radius of each circle represents the______ to the epicenter Seismic station ___ feels and records the earthquake first. Seismic station ___ feels and records the earthquake second. Seismic station ____ is 1200 km away from the epicenter
