Richter magnitude scale

Breaking news: Just yesterday at 4:53 pm, the country of Haiti was Figure 1: Port-Au-Prince flattened by 7.0 earthquake. flattened by a devastating earthquake with a magnitude of 7.0 causing major destruction. The epicentre was 13 km from the capital of Haiti, Port-Au-Prince. The initial estimates for this disaster, placed the death toll around 210,000. Sadly, this estimate was horribly wrong with the death toll rising well above 300,000. There were many reasons for the death rising so high,…

A tsunami is a seismic sea wave. Displacement of water forms a sequence of waves and this generally happens in an ocean or a large lake.Tsunamis are different because normal waves are caused by wind or tides, which is actually generated by the gravitational pull of the Moon and Sun. According to Source 1, the first recorded tsunami was back in 7000-6000 BCE and this was in Portugal but the primary cause is unknown. Since then there have been many tsunamis that have caused damage, two of the…

Deep injection fluid induced earthquakes can be felt and are usually the result of wastewater injection, but recently hydraulic fracturing injections are becoming more common at low magnitudes (Petersen, et al, 2015). A case study was performed in the Horn River Basin, which is located in northeast British Columbia, where seismicity (earthquakes) were monitored before and after hydraulic fracturing (Farahbod, et al, 2015). The Natural…

Introduction On December 26, 2004, at approximately eight in the morning, there was a huge earthquake that struck the Indian Ocean. The magnitude of this earthquake was a 9.3 on the Richter scale. According to this scale, anything over a 9 results in “near-total destruction, waves moving through the earth visible with naked eye. The epicenter was off the coast of Sumatra, Indonesia. According to the California Institute of Technology, this earthquake ruptured the greatest fault length of 1500…

The Signal and the Noise by Nate Silver is about making an assessment based on future outcomes. Prediction is indispensable to our everyday lives. The biggest problem with predicting about the future is even though you are forecasting the future the data it is based off is usually from the past. Just because you are able predict the past doesn’t mean you are able to predict the future. Silver demonstrates in this book how many prediction practices have been flawed and suggest ways that might…

com/weather-earthquake.htm majority of earthquakes take place on the west coast of North, Central, and South America. As well as India, the Philippines, New Zealand, an eastern parts of Africa. The Richter scale is a device that measures the magnitude of an earthquake, one being the least destructive and ten being the worst. That scale is what classifies the quake as a main shock or an aftershock. Aftershocks are other earthquakes in nearby locations due to the main shock, almost like a domino…

are affected each year as a result of earthquakes. Also, earthquakes costs the world economy US$12,106,198,000 per year on average, with most expenses coming from Japanese earthquake damage. The highest magnitude earthquake was recorded in Alaska in 1964, measuring in at 9.2 on the Richter scale. One of the most recent devastating earthquakes occurred in Nepal in March, 2015,…

smaller earthquakes and has some large ones throughout the years. The most remembered earthquake in California history is the Great San Francisco quake of 1906 with a magnitude of 7.8. The death toll here was about 3000 and much of the city was in disaster after many buildings were not ready for the seismic activity of this magnitude. After this event, many codes were to be passed and buildings had to be inspected and passed for structural safety. These codes have been built on for many years as…

phreatic eruption took place. A phreatic eruption is an explosion of steam caused by magma heating groundwater. Many more earthquakes with magnitudes as high as 5.1 on the Richter scale continued. By the end of April, the side of the mountain started to bulge out due to magma pushing up the pipe. The earthquake that caused the volcano to erupt was a magnitude 5.1 earthquake. The entire north face slid away due to the earthquake causing the largest landslide ever recorded. The earthquake exposed…
