What do you mean by the focus of an earthquake?
GeologyThe focus is the place inside Earth’s crust where an earthquake originates. The point on the Earth’s surface directly above the focus is the epicenter. When energy is released at the focus, seismic waves travel outward from that point in all directions. What is the focus of an earthquake class 7? Focus is the location

What happened in the Alaska Earthquake 1964?
GeologyThe four minute duration of shaking triggered many landslides and avalanches. Major structural damage occurred in many of the major cities in Alaska. The damage totalled 300-400 million dollars (1964 dollars). The number of deaths from the earthquake totalled 131; 115 in Alaska and 16 in Oregon and California. What caused the tsunami in Alaska
Are aftershocks bigger than the earthquake?
GeologyAftershocks are smaller earthquakes that occur in the same general area during the days to years following a larger event or “mainshock.” They occur within 1-2 fault lengths away and during the period of time before the background seismicity level has resumed. Are aftershocks stronger than earthquakes? Aftershocks are sometimes just as hazardous as the
What type of fault is Wasatch Fault?
GeologyThe Wasatch fault is called a normal fault, because the slip is mostly vertical – the mountain block (Wasatch Range) moves upward relative to the adjacent downward-moving valley block. The 240-mile-long fault is sectioned into 10 segments averag- ing 25 miles in length. Each segment can rupture independently. What kind of fault is in Utah?
