Tsunamis are ocean waves triggered by large earthquakes that occur near or under the ocean, volcanic eruptions, submarine landslides, and by onshore landslides in which large volumes of debris fall into the water. Scientists do not use the term "tidal...
Although earthquake magnitude is one factor that affects tsunami generation, there are other important factors to consider. The earthquake must be a shallow marine event that displaces the seafloor. Thrust earthquakes (as opposed to strike slip) are far...
Although both are sea waves, a tsunami and a tidal wave are two different and unrelated phenomenona. A tidal wave is the wave motion of the tides. A tidal wave is a shallow water wave caused by the gravitational interactions between the Sun, Moon, and...
To view a map of latest earthquakes or report a felt earthquake, check the Real-time Earthquake Map. Make sure you're Control Panel settings are allowing you to see earthquakes of all magnitudes. If you find an earthquake on the map near your area, click...
Go to the Earthquake Hazards Program Real-time Earthquake Map.  There are three columns which make up the real-time earthquake map.  The left column comprises the list of earthquakes, the center column is the map itself, and the right column is the...
The actual rupture duration on the fault (the time it took for the earthquake to take place on the fault and rupture the entire length) was approximately 3 to 4 minutes. The exact length of time that people felt the shaking varied from place to place,...
Felt earthquakes on Mount Hood (Oregon) occur every 2 years on the average. Seismic monitoring, in effect since 1977, indicates a generalized concentration of earthquakes just south of the summit area and 2-7 kilometers below sea level. A seismic swarm...
The occurrence of this earthquake will have produced a redistribution of tectonic stresses along and near the boundary between the India plate and the Burma plate. In some areas, this redistribution of stresses will be such as to shorten the time to the...
Volcano eruptions have occurred shortly after earthquakes and they may be linked, but scientists are still debating the topic. Notably, an Andean volcano (Cordon Caulle) began erupting 2 days after the magnitude 9.5 1960 Chile earthquake. Eruptions of...
Theoretically yes, but realistically the answer is probably no. The magnitude of an earthquake is related to the length of the fault on which it occurs. That is, the longer the fault, the larger the earthquake. A fault is a break in the rocks that make...
