An active volcano is one that is currently erupting or shows signs of erupting in the near future. A dormant volcano no longer shows signs of activity, but has erupted in recent history (Figure 8.19).An earthquake occurs when two blocks of the Earth suddenly slip past one another. The surface where they slip is called the fault or the fault plane. The location below the Earth’s surface where an earthquake begins is called the hypocentre, and the location directly above it on the surface of the Earth is called the epicentre.Recent Earthquake Incidents in Bangladesh.

With the constant influx of online information, it’s easy for our bookmark folders to become cluttered and disorganized.Most earthquakes occur along the boundaries between the Earth’s tectonic plates. The crust of the Earth is divided into plates. When a plate collides with or slides past another plate, this causes earthquakes.An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. Earthquake. The surface of the Earth is made up of tectonic plates that lie beneath both the land and oceans of our planet. The movements of these plates can build mountains or …Locating an Earthquake P and S waves travel at different speeds. This is key to locating where an earthquake occurs. Scientists use the time difference between the arrival of the P and S waves to determine the distance to an earthquake epi-center. If the earthquake is close by, the time lag between the arrival of the P and S waves will be short.An earthquake is the shifting of the Earth’s plates, which results in a sudden shaking of the ground that can last for a few seconds to a few minutes.
