The intensity of shaking during an earthquake diminishes as the depth increases. That's why the 4.8-magnitude earthquake that hit California at a depth of 19.2 miles Monday had a lower impact.Richter scale, widely used quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. Magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph.Earthquakes are natural phenomena which cannot be controlled, but their effects can be minimised. This study proposes a state-of-the-art review of the main effects of earthquakes on civil engineering structures and provides possible mitigation solutions to reduce seismic vulnerability. The main aspects reviewed include the liquefaction in dams and tunnels, the cracking and tilting of roads and ...

The Earthquake Risk Reduction in Buildings and Infrastructure Program addresses these needs by (1) developing key measurement science tools to mitigate seismic risk to new and existing buildings and infrastructure systems and (2) supporting the nation through development of improved building codes and new design approaches.USGS Earthquake Hazards Program, responsible for monitoring, reporting, and researching earthquakes and earthquake hazards.

Oct 18, 2023 · Earthquake intensity and magnitude measure different things and are often misunderstood, and it is shaking that links them. Earthquake intensity is a measurement of damage. Earthquake magnitude is a measurement of the "size" of the quake - typically related to the amount of energy released. There is one magnitude for an individual quake, but ... Measuring earthquake intensity. Seismologists used to assign magnitudes to earthquakes using the Richter scale. Recently, scientists have begun to use the more precise moment magnitude scale, which measures the total energy released by a quake.The earthquake struck below the North Pacific, 130 kilometers (81 miles) east of Sendai, the largest city in the Tohoku region, a northern part of the island of Honshu. The Tohoku earthquake caused a tsunami. A tsunami—Japanese for “ harbor wave ”—is a series of powerful waves caused by the displacement of a large body of water.
