How deep was the focus of the Haiti earthquake?
Assuming that you are referring to the earthquake that occured in January 2010, the focus or hypocentre (the point within the Earth where the rupture actually occurred) was located at a depth of 13 km below the surface. Please see the related question for further information.
Exact location of current Haiti earthquake?
The epicentre of an earthquake this the point in the earth where the earth moved (fractured) to cause the shaking of the ground. The 2010 Haiti earthquakes epicentre was located 15 miles WSW of Port-Au-Prince and was at a depth of 8.1 miles. it was a 7.0 magnitude earthquake.
What fault did the Haiti earthquake occur on?
Haiti is sandwiched north and south between two fault lines: the Septentrional Fault and the Enriquillo-Plantain Garden Fault. The epicenter of the Haitian earthquake of 12 January 2010 was 10 miles south of the capital Port Au Prince, directly on the Enriquillo-Plantain Garden Fault , at a depth of about 5.2 miles underground.
What is the focal depth of the Great Sumatra Andaman Earthquake?
The focal depth of an earthquake is how far beneath the earth's surface the hypo-center of the earthquake.Because of its location in the Indian Ocean, however, its focal depth is measured as 30 kilometers below mean sea level, rather than being measured at the seabed.
Why did the Haitian earthquake cause so much damage?
The earthquake was so destructive for a number of reasons:The earthquake occurred at shallow depth - this means that the seismic waves have to travel a smaller distance through the earth to reach the surface so maintain more of their energy in particular this meant that the surface waves (which cause the vast majority of the damage during an earthquake ans which are the most rapidly attenuated and and have significant reductions in amplitude as the depth of the earthquakes focus increases) produced by the earthquake maintained a large amount of their energy maximising the damage they cause.The earthquake occurred in close proximity to a populated area. This again means that there is very little attenuation of the seismic waves (i.e they still have most of their energy and so are more destructive when they arrive).The buildings in Port-au-Prince and other areas of Haiti were in very poor condition in general and were not designed or constructed to be earthquake resistant.Please see the related question for further information.
Where was the epicentre and hypocentre of the earthquake in Haiti on January 12 2010?
The earthquake's epicentre (the point on the surface directly above the earthquake rupture zone) was 25 km WSW of the Haitian capital city, Port-Au-Prince. According to the US Geological Survey the exact co-ordinates were 18.457°N, 72.533°W. The hypocentre (the point within the Earth where the rupture actually occurred) was located at a depth of 13 km below the surface. Please see the related links and question.
How powerful was the Christchurch earthquake?
The Christchurch earthquake that occurred in 2011 had a magnitude of 6.3. It caused widespread damage to buildings, infrastructure, and resulted in numerous casualties. The overall impact was significant due to the shallow depth of the quake and its proximity to urban areas.
What is the depth of focus of an earthquake whose magnitude is 7.2 below sea level?
The depth of focus of an earthquake with a magnitude of 7.2 can range from 10 to 700 kilometers below the surface of the Earth. At this depth, the earthquake originates within the crust or upper mantle, releasing energy that can cause significant shaking and damage near the surface.
Why was the death toll so high in the Haitian 2010 earthquake?
Haiti's a very congested country, there are small buildings and houses as far as the eye can see. A 7.0 earthquake would crush any small structures in it's vicinity. Plus there were at least 52 aftershocks ranging from 4.5 up.The earthquake was so destructive for a number of reasons:The earthquake occurred at shallow depth - this means that the seismic waves have to travel a smaller distance through the earth to reach the surface so maintain more of their energy.The earthquake occurred in close proximity to a populated area. This again means that there is very little attenuation of the seismic waves (i.e they still have most of their energy and so are more destructive when they arrive).The buildings in Port-Au-Prince and other areas of Haiti were in very poor condition in general and were not designed or constructed to be earthquake resistant.
What information do you need to completely describe where an earthquake started?
To completely describe where an earthquake started, you would need the coordinates of the earthquake's epicenter, the depth at which it originated within the Earth, and the fault line or tectonic plate boundary where the earthquake occurred. This information helps to pinpoint the exact location and provide insight into the geological context of the earthquake's origin.

What is the maximum depth of natural earthquake?
