![]() Videos - Concise video lectures give background information on the Earth and plate tectonics for teaching how earthquakes happen and how they are studied. Significant faults include the Philippine fault that traverses the entire Philippine archipelago for more than 1250 km and has generated at least ten surface rupturing earthquakes for the past 200 years (Perez and Tsutsumi, 2017), the Owen-Stanley fault zone that on land is continuous 510 km-long left-lateral strike-slip fault that forms a. Software-Web-Apps - Stand alone software, interactive web tools, and downloadable apps to help you explore seismic data and earthquake topics. Posters - More than just wallpaper, these eye-catching, educative posters invite students to become minds-on with Earth's internal structure, earthquakes, seismic waves and more! The component parallel to the dip of the fault is called the dip slip. Lessons - A step-by-step guide outlining what students will learn across one or more class periods, through a progression of activities, combined in a learning cycle, to achieve the desired student learning. The strike slip may be characterized as sinistral (or left-lateral) or dextral (right-lateral). ![]() ![]() Interactives - Uses interactive Flash (sfw) to illustrate fundamental concepts that are difficult to convey to learners through other means. Faults that have a small up or downward motion as they move horizontally are oblique-slip. It can count higher than most cats.Į-mail C.E.IRIS offers a range of resources for students, educators and the general public.Īctivities - Bite-sized (5, 15, or 30 minute) demonstrations or student tasks tied to ‘Did You Know?’ questions to engage the learner.Īnimations - Concise animations that illustrate fundamental concepts that are difficult to convey to learners through other means (the real events may be too small, too large, too fast, too slow, or unsafe for the classroom).Ĭourse - A series of lessons that provide the structure for a semester-long undergraduate course.ĭemos - Quick teacher-lead activities (show-and-tell combined with an opportunity for learners to ponder, predict and discuss) to stimulate interest and convey a concept to learners.įact-Sheets- Single page, accessible, discussions of earthquake related topics. If the land moves to the left it is a left-lateral strike slip fault. Two major earthquakes (MW 7.8 and MW 7.7) ruptured left-lateral strike-slip faults of the East Anatolian Fault Zone (EAFZ) on February 6, 2023, causing >59,000 fatalities and 119B in damage in. This cat has just spotted some strike-slip fault motion. Because you have to step to the right to go from one side of the volcano to the other, this is a right-lateral strike-slip fault. This is the remains of a cinder cone that erupted along a strike-slip fault in the southern end of Death Valley, CA. If it requires a jog to the left, it was a left-lateral fault that did the offsetting. If you have to go to your right to make the connection, you have a right-lateral fault. To determine what type you've got, figure out which way a particular object, say a road or a fence, was offset by the fault motion. Strike-slip faults are either right-lateral or left-lateral. Strike slip faults involve motion in a horizontal plane: they are best spotted from the air! This makes them relatively easy to spot in a road cut or mountain side. The MF is a roughly east-west right-lateral strike-slip fault that demarks the boundary between the Gorda Plate to the north and the Pacific Plate to the south. Normal faults, reverse faults, and thrust faults all involve a substantial amount of vertical motion. In normal usage faults with slip-vectors lying within 10 -15 of the dip or strike orientation (not direction) are termed normal/reverse or right-/left-lateral.
