The largest known British earthquake occurred near the Dogger Bank in 1931, with a magnitude of 6.1. Earthquake belts; About 95% of the energy released by earthquakes originates in a few relatively narrow zones that wind around the globe. Seismographs are machines that detect and measure seismic waves caused by earthquakes. The fault surface can be vertical, horizontal, or at some angle to the surface of the earth. Faults allow the blocks to move relative to each other.

Faults can be as short as a few metres and as long as 1000km. This Science quiz is called 'Earthquakes' and it has been written by teachers to help you if you are studying the subject at middle school. Day 3: Magnitude: watch video Perspective, answer the preliminary questions before watching: The 4 types of Seismic Waves. 8 th Grade 8. Rates of Earthquake Occurrence. Mention statewide and local awareness programs (such as the ShakeOut) that help communities prepare and practice for such events. The strength, or magnitude, of an earthquake, is measured using the Richter scale. Locating an Earthquake with Recent Seismic Data. Scientists identify four types of faults, characterized by the position of the fault plane, the break in the rock and the movement of the two rock blocks. Major earthquake zones include the Circum-Pacific belt, Mediterranean Sea region to the Himalayan complex, and the oceanic ridge system. An earthquake is a shaking of the ground caused by the sudden breaking and movement of large sections (tectonic plates) of the earth's rocky outermost crust. Sometimes there can be short offsets between parts of the fault, and even major faults can have large bends in them. Dissecting a Tropical Cyclone Module 3. 2. Elastic rebound Earthquake mechanism Slippage at the weakest point (the focus) occurs. Spaghetti Fault. Stop at Magnitude. A. This module explains how earthquakes occur. 2 Introduction • Earthquakes represent the vibration of Earth because of movements on faults. This video was recorded by a surveillance camera and shows a street scene in Katmandu during the magnitude 8 earthquake in Nepal. UNDERSTANDING TYPHOON Activity 1. Faults Faults are blocks of the earth’s crust that meet together. The frequenct at which the least amount of energy is necessary to cause a specific object to vibrate. Take this quiz on 8th-grade science and share with friends too. 3 fault to fault answer card assessment 1. earthquake is the sudden and violent shaking of the ground. Tsunami! The Himalayas are a hotspot for earthquakes. The fault rupture from an earthquake isn’t always a straight or continuous line. Quakes measuring around 7 or 8 … Science – Grade 8 Alternative Delivery Mode Quarter 2 – Module 1: Faults and Earthquake First Edition, 2020 Republic Act 8293, section 176 states that: No copyright shall subsist in any work of the Government of the Philippines. C. 1 . Various studies have placed it at 9.4 9.6 on the moment magnitude scale. Learn vocabulary, terms, and more with flashcards, games, and other study tools. B. Joists. Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving. An M6 earthquake releases 7.8 x 10 13 joules, and an M7 radiates 2.1 x 10 15 joules. (v) To provide earthquake proof structures it is necessary to have a knowledge of the location and earthquake potential of faults. A fault is a fracture or zone of fractures between two blocks of rock. Katmandu 2015 Earthquake. 2 fault finder images with faults answer card activity no. 7th grade Science; 2 Earthquakes. Use the information below and your chapter 11 in your textbook (p. 300-322) to answer … A perfect review and reinforcement tool that is a two pages worksheet consists of 10 questions on earthquakes. Make an Earthquake! A Model of Three Faults. P waves, or primary seismic waves, are the fastest moving waves. JumpStart’s ‘Natural Calamity: Earthquakes’ is a free, printable earth science worksheet that helps 4th graders improve their earthquake vocabulary. It occurred in the afternoon (19:11 GMT, 15:11 local time), and lasted approximately 10 minutes. For more information, visit shakeout.org. 11. It resulted from a displacement, or movement, of the Fault by 6 metres. What Is an Earthquake?

Fortunately, it was 60 miles offshore but was still powerful enough to cause minor damage to buildings on the east coast of England. Vibrations (earthquakes) occur as the deformed rock “springs back” to its original shape (elastic rebound). The boundary between the earth's crust and mantle that causes earthquake waves to change speed. This PPT is 6 slides long, and includes important information about Earthquakes, such as Fault zones. An earthquake is the result of a release of stored energy in the Earth's crust that creates seismic waves. Using an informative video presentation, viewers learn how scientists reference history and GPS technology to predict future occurrences. Plug magnitude values of 5.0, 6.0, and 7.0 into the equation above. Activities. The edges of the tectonic plates are marked by faults (or fractures). Detect an Earthquake . _____8. The scale that measures an earthquake based on its type of damage is called: This is of particular importance in locating sites for dams and reservoirs, hydropower structures, underground power, nuclear power stations, tunnels, public buildings, school and college buildings etc. Earthquake Videos Be careful since some of these can be disturbing - not necessarily for student eyes. answer card activity no. This relationship was only meant to work for fairly big (M > 5) earthquakes. The 1960 Valdivia earthquake or Great Chilean earthquake of 22 May is the most powerful earthquake ever recorded. The key information covered on this PPT includes: Normal, Reverse, Strike-Slip Faults, Divergent, Convergent, Transform Boundarie Faults may range in length from a few millimeters to thousands of kilometers. Earthquakes occur on faults - strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. 1 before and after images before an earthquake images after an earthquake answer card activity no.

Most faults produce repeated displacements over geologic Q. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other. They travel through solids, liquids and gases. A. Moho. Playing educational quizzes is a fabulous way to learn if you are in the 6th, 7th or 8th grade - aged 11 to 14.
