When Mount St. Helens erupted it took lives and destroyed at least fifty miles of the surrounding area. A volcano is a mountain or hill where a vent forms in the earth’s crust, letting ash, lava, and steam escape. Mount St. Helens included many details common to volcanic eruptions, caused damage and destruction, and how the area has recovered. Volcanoes are classified with the Volcanic Explosively Index (VEI) scale. Mount St. Helens was ranked at a five, the highest is an eight. The volcano erupted

​The claim that is correct is claim 3. The Jalisco Block is convergent to the Rivera Plate and divergent from the North American Plate which best explains the patterns of Earthquakes and Volcanoes on the Jalisco Block. I believe at this claim is correct because fro any plates to be convergent to one plate, they must be divergent to another plate. This case happens for the Jalisco Block. The card that support this statement is card A which tells us that scientists found the same rock on either

Name: Olawale Oluwakoya Media report: The likely cause of recent southeast US earthquakes. The southeastern part of the United States should not encounter too many seismic activities because it is located in the interior of the North American Plate, a good distance away from plate boundaries where earthquakes mostly occur. However the southeast have seen some seismic, the latest was the 2011 magnitude-5.8 earthquake at Virginia. Scientists recently reported in a new study a likely explanation for

Shake Maps Shake Maps provide an alternative way to investigate a seismic event, with an emphasis more on surface strength and its impacts, than in ground- motion modelling. Shake maps rely on the use of the Modern Mercalli Intensity scale (referred to in the rest of this literature review as the MMI scale) to represent the strength an earthquake. MMI is a scale which is used to show the strength of an earthquake, with regards to the damage it causes. This is an area of investigation for the 1906

The San Francisco earthquake was the first time man had ever seen the most disaster city of the state of California had ever seen. Most people think that it took hours and hours but it took a minute. But no one would ever know. And now the greatest disaster ever. But it took so many lives though. You might wondering how earthquakes happen. An earthquake is when the rocks break apart and slide by each other. If the world didn't move and rotate earthquakes wouldn't happen. The falt is where the

A 7.1 magnitude earthquake struck Alaska, which led to explosions due to gas leak in four houses, but there were no reported injuries. Many Alaskans woke up in the middle of the night at 1:30 am local time, about 162 miles from Anchorage in Kenai Peninsula in southern part of the state. About 20 people were evacuated from their homes, and two homes exploded of gas leak several hours after the earthquake, while the other two were destroyed by fire, according to The Sacramento Bee. The evacuated

The Market Street Railway, Sutter Street Railroad, and the San Francisco & San Mateo Railway merged in 1902 to become the United Railroads of San Francisco (URR). The URR was created by the aggressive capitalist consolidator and modernizer named Patrick Calhoun. An early project was to make uniform the rolling stock and track gauges, which led to the abandonment of the last four miles of horsecars that had been the backbone of transportation just a generation earlier. By this stage, the company

On October six a small earthquake shook part of southern California. It started along the Newport-Inglewood Fault near Long Beach, California. The quake itself was weak and not cause any damage to the local. However the significant part about this earthquake is that it originated from ten kilometers underground, or about 6.2 miles. Which was interesting because seismologists report on October seventh. That Rocks at that depth should be too hot and malleable to snag and break. Which is a key cause

Hanger Wire The primary support for the exposed grid system are hanger wires, also known as suspension wires. See Figure 7. Hanger wire has a minimum strength requirement of 12-gauge, galvanized mild steel wire. Hanger wire attaches to main runners within 8" of the perimeter walls and spaced 4' o.c. along the main runner. A hanger wire is required for cross tees when they exceed 8" in length along the perimeter boundaries of the ceiling. There are many methods to attach hanger wires to the structure

Introduction Oklahoma has been on the spotlight for the last few years owing to the increase in earthquakes. Particularly, 2014 served a wake-up call for stakeholders such as government, researchers and oil and gas industry members as a result of a sharp rise in earthquakes reported in the area. The year saw Oklahoma receiving more earthquakes than compared to California, a region that is more culpable to the earthquakes scene. In adition, 2014 also marked the largest earthquake reported in the history
