Makran province experiences low to moderate earthquakes with low frequency, very long repeat time and down to 20Km focal depth
. The intensity of earthquakes is in the middle to high levels.
where [F.sub.2] is the required focal depth
in the investigated specimen.
If the structure generates a subwavelength long focal depth
and satisfies the limiting conditions of side lobe intensity of less than 15%, it is chosen as the initial structure during the optimization procedures.
An epicenter of magnitude (Less than) 4.9 with focal depth
of 5 km is located just to the south of MandiBaha- ud-din.The event probably originated from some structure within the cover sediments of the shield.
East of Gebel Marawa Zone: This zone, north east of Gebel Marawa zone, is located along Kalabsha fault and the focal depths
of the events are shallow (between 3 and 7 km depth).
Based on the dip angle and location of the focal depth
, subduction zones was divided into interplate (megathrust) and intraslab (benioff) zones.
more distant stations), only low impact on epicenters, but dominant influence on focal depth
Geological Survey (USGS) said the earthquake's magnitude was 6.2 and its focal depth
was 203 km in Ashkasham area of Afghanistan.
According to the Website of Pakistan National Seismic Monitoring Centre, the epicentre of the quake was in Nepal (Location Coordinates 28.13 N, 84.63 E) with focal depth
of 12 km.
The mean errors of the analytical locations are, respectively, 0.95 km for the epicentral coordinates and 1.15 km for focal depth
; the mean root mean square (RMS) is 0.16 s.
The shallowness of the earthquake (10 km focal depth
) and frequent aftershocks contributed significantly to the destruction.
Figure 4 shows that the 1993 focal depth
started with more than 10 km for foreshocks, no foreshock having less than 10 km depth.
Determined focal depth
is h = 3[+ or -]1km for both events.
The epicenter of the quake was located on 20 km away from the east Bannu while the focal depth
The tremblor was recorded west of Athens at 6.02 am (0402 GMT) in the Corinthian Gulf, with assessments giving it a focal depth
of 5 kilometres, the National Observatory of Athens said on its website.
