5 The majority of the research shows that the plates move at the average rate of between approximately 0.60 cm/yr to 10 cm/yr. Some sources state that in the North Atlantic, the rate of movement is only about 1 cm (about 0.4 in) per year, while in the Pacific it amounts to more than 4 cm (almost 2 in) annually, while others say that plates, in general, travel from 5 to 10 cm/yr.

6 Warm colours show regions with the highest probability of strong shaking, which tend to be located near, or influenced by, major plate boundaries. Earthquake clustering in mid- continental areas such as New Madrid and Charleston is here interpreted to reflect continuing deformation sufficient to produce frequent large earthquakes.

9 1. What is pyroclastic flow? superheated volcanic dust and gases. 2. How did the pyroclastic flow kill the group of scientists and press? Their lungs were burned by the pyroclastic gases. 3. What is the Pacific Ring of Fire? Active volcanoes that circle the Pacific Ocean. 4. Where are the volcanoes in the Pacific Ocean located? The volcanoes occur along subduction zones around the Pacific ocean.

10 5. What is common along the Pacific Ring of Fire? 6. What causes the frequent earthquakes in the Pacific Ring of Fire? 7. Which areas in the United States are most prone to earthquakes? Why?

12 When Mount Vesuvius erupted cataclysmically in the summer of A.D. 79, the nearby Roman town of Pompeii was buried under several feet of ash and rock. The ruined city remained frozen in time until it was discovered by a surveying engineer in 1748.

15 Hot Spots Volcanoes https://www.youtube.com/watch?v=AhSaE0omw9o Mantle plumes are areas of hot, upwelling mantle. A hot spot develops above the plume. Magma generated by the hot spot rises through the rigid plates of the lithosphere and produces active volcanoes at the Earth's surface. As oceanic volcanoes move away from the hot spot, they cool and subside, producing older islands, atolls, and seamounts. As continental volcanoes move away from the hot spot, they cool, subside, and become extinct.Magmahot spotlithosphereextinct

16 5. What is common along the Pacific Ring of Fire? Earthquake is most common in the Pacific Ring of Fire. 6. What causes the frequent earthquakes in the Pacific Ring of Fire? The Pacific plate is constantly shifting and subducting beneath the continental plates. 7. Which areas in the United States are most prone to earthquakes? Why? Alaska and the Pacific North-West
