Earthquake slip classroom exercise earthquakes can provide a useful context for teaching or reviewing many basic physics concepts, such as sliding and static friction, forms of energy and conversion from one form to another, and the elastic properties of materials. Locating the world series earthquake epicenter p and s waves generated by the world series earthquake traveled away from the epicenter and were recorded at the three locations on the map below click each city on the map to see the seismogram and travel-time graph for that location. The epicenter ofan earthquake is usually determined by examining seismograms from at least three recording stations from these records, the distance to the epicenter of the. Mystery epicenter group #1 1 mark the first arrival of the p‐wave on each seismogram 2 mark the first arrival of the s‐wave on each seismogram.

Part a - epicenter determination the epicenter of an earthquake is the point on earth's surface at or above the earthquake's focus in this exercise, you will determine the location of the. Using the distance to epicenter information above, the map and map scale, plot the location of the earthquake this can be done by drawing circles with the appropriate radius around the cities of record, and identifying where the circles. Explain why earthquakes are common in this region of california 9 of the cities shown on the map, explain why oakland was the last city to receive p-waves from this earthquake.

Locating the epicenter of an earthquake introduction: the epicenter is the point on earth's surface directly above an earthquake seismic stations. Earthquake epicenter introduction an earthquake epicenter is the point on the earth's surface directly above the earthquake focus the epicenter is the geographical location of the earthquake reported on television stations and written reports about earthquakes.
1 earthquakes physical geology 2017 adapted from a lab by jennifer wenner this lab is designed to give you experience exploring seismicity associated with different plate boundaries. Lab worksheet - earthquake 1 if the difference in arrival time for p and s waves at a certain location is 3 min, how far from that if a seismograph is located. 4 next, find the earthquake's epicenter, using the distances just obtained and the procedure below use the scale in figure 2 to set the appropriate radius on your compass. Step 2 after you have table 1 completely filled-in, use the drafting compass to draw circles on map 1 (follow the instructions of your ta) the intersection of the three circles will be the epicenter. The hypocenter or the focus of the earthquake (the epicenter is the place on the surface directly above the focus there is a distinctive pattern of first motion right around the focus, as shown below.
Geodetic data currently to make geodetic observations the usgs uses the global positioning system (gps) and also other techniques ( creepmeters, tiltmeters, strainmeters, magnetometers, pore pressure monitors . To locate the epicenter of the earthquake, a minimum of 3 circles from three different seismic stations must be drawn on the map the intersection of the three circles shows the location of the epicenter on the map. This is a lab to help students explore the triangulation method used to determine earthquake epicenters i created this lab because i wanted a lab that very purposefully made students practice the analysis of seismogram data, calculate pertinent information such as "lag time" from p-wave and s-wave data and use triangulation to determine epicenter.
This feature is not available right now please try again later. The geosphere 05: earthquake epicenter lab introduction: your task will be to locate the epicenter for the earthquake using the arrival time of p-waves and s-waves from several seismic stations. Analyzing the location of earthquake epicenters and estimating earthquake magnitudes i believe that these sets of web-based, interactive exercises nicely compliment the activities in your lab book.
Transcript of lab report format for earthquake epicenter lab conclusion: if you are unsuccessful at locating the epicenter, i wasn't able to get the correct answers locating the epicenter of an earthquake youtube, here is the link to the activity. Make an earthquake students will learn about the different waves generated during an earthquake this experiment will help them visualize how p waves travel through earthquakes. Distance from a city to the epicenter of an earthquake determine the location of an earthquake epicenter using the distance from three different cities to the epicenter of an earthquake.
