Sub surface Fault

Sub surface fault is a fault located beneath a surface, invisible to people above. While conventional fault is easily detectable by seeing difference in rock type, or displacement over placemarks like fence, road, or cracks at wall, sub surface fault is hard to detect. A subsurface fault might be a fault which is active, but its presence is covered by a layer of sediments / rock of same type - so any displacement made by the fault is 'seems to be invisible'. One way to detect a subsurface fault is by doing a research over seismic data; I mean, firstly we should have a data of earthquake occurence around our area of interest. Then we do a more comprehensive geophysical survey like raw seismic data processing with computer programs. Then we can correllate the result of data processing to the shape of fault and even how it's moving. Another try to know how is the subsurface fault looks like is by doing geoelectrical survey or seismic survey, but it's unlikely to be success if it done in / near a densely populated area.

Conventional fault, Bordeaux, France (wikipedia)

Subsurface fault in Iraq, near Tigris river. This fault is invisible to people above because it is covered with Tigris river's deposits. The corresponding geoelectrical pseudo-resistivity is shown below. These data are obtained after Nabeel Hameed Al Saigh in this paper. We could see that the densest contour is corresponding to change in rock type and thus it may be concluded that there is faulting activity there.

In the case of Haryana earthquake, I really have no idea how the fault is moving. But by seeing the geological map of India, the case seems like that of Tigris River: A subsurface fault covered by Yamuna river deposits has triggered 5.5 M earthquake. Video here, in NDTV (the earthquake movement is not obviously seen but people runs out). Unfortunately, there is no fault plane solution so I can't infer the fault movement. But from seismograph record here I might say that this sub surface fault would be a normal one. For reader, correct me if I'm wrong haha :-).

Radio Blackout affecting Sunlit side of the Earth

In response to the X class flare ( Intensity being estimated) by the Sunspot 1429,A former R3 now R2 Radio Blackout is affecting the sunlit side of the Earth
As seen from this image,the higher frequency signals are being largely attenuated due to the Radio Disturbance as the signals propogate through a disturbed ionosphere..

Mega Solar Flare from Sunspot 1429!!

SEVERE SOLARWX
AKSHAY DEORAS
SEVERE WEATHER FORECASTER

AFTER A BRIEF PERIOD OF QUIET SPACE WEATHER,OUR SUN IS WAKING UP DUE TO THE SUNSPOT AE 1429. The Sunspot is 4 times the size of the Earth.
The GOES X Ray flux is indicating a major Solar Flare in progress and a R3 Radio Blackout is in progress on the Sunlit side of the earth including here in India at the Higher Frequency

Solar disc is rotating and hence the sunspot 1429 will become geoeffective after some days... If it hurls another X class flare then that may be a source of big problem

Stay tuned as the event unfurls
