There
is no gain saying the fact that the people of Kaduna state have been
living in fear following the recent earth tremor that occurred in Qei
and Jaba area of Jaba Local Government Area of the state. It also
happened in in Kwoi and surrounding villages of Nok, Sanbah and Chori in
Jama Local Government Area of Kaduna State on Sunday 11th and Monday
12th September, 2016.
In a swift reaction to the incident on
Wednesday, the National Space Research and Development Agency (NASRDA)
attributed the cause of the recent tremor in Jama Local Government Area
of Kaduna State to Passive sources. NARSDA, which spoke through its head
of media and corporate communications, Dr, Felix Ale said that the
nature of the source will soon be determined after the completion of yet
another on-going thorough and further investigation of the incident by
experts in the Space Agency.
The current findings, according to
NARSDA was the outcome of a preliminary report by the team of experts
immediately deployed to the affected communities from one of the
activity centres of the Space Agency: The Centre for Geodesy and
Geodynamics for on the spot assessment and to carry out a survey and
investigation on the incident.
The team which was led by the Head of
Seismology division of the Space Agency, Dr. Ofonime Akpan, established
that the Seismological Station of NASRDA located at Kujama in Kaduna
State accurately recorded the unfortunate incident which made it easy
for collation of data and early release of preliminary reports on the
incident.
The analysis showed that the first event
occurred at 12:28:16.50 seconds GMT on Sunday 11th September, 2016 and
the event had an epicentre located Latitude 9.825N and Longitude 7.885 E
while Local Magnitude was 2.6 and Moment Magnitude was 3.0 and Focal
Depth was 10km. The report further revealed that the second event
occurred on Monday 12th September, 2016 at 03:10:48.80 seconds (GMT)
with Local Magnitude of 2.6 and Moment Magnitude of 2.9 with Focal Depth
of 10km while the epicentre was Latitude 10.879N and Longitude 7.188E.
This was followed immediately by another
event at 03:11:20.00 seconds (GMT) located at an epicentre of Latitude
9.927N and Longitude 7.297E, Local Magnitude 2.9 and Moment Magnitude
3.0. The reports revealed that the time of occurrence of these events
and intensities of the locations as reported by inhabitants of the
communities which included cracks on walls of buildings, falling off of
ceiling fans and other items corresponded with the results of analysis
carried out by the team of experts from NASRDA’s Centre for Geodesy and
Geodynamics.
