00:00National Geophysical Research Institute came here from Hyderabad to Adanki province.
00:13As you know, on Saturday, there was an earthquake of magnitude 3.1 near Adanki province.
00:28After that, with very low intensity, we call these micro-earthquakes,
00:33with very low intensity, with very low energy, some earthquakes occurred.
00:39Because of this, the people here, some of them,
00:43due to fear, some of them, due to fear, some of them,
00:46the state government officials like RDO madam,
00:51the collector's office, our organization,
00:54got information about the situation here.
00:59So, here in Adanki province, basically,
01:04there is something called Seismic Zone Map of India.
01:08In that, it comes under Zone 3 section of Adanki province.
01:14In Zone 3, there is a possibility of earthquakes with moderate energy.
01:22Why? Because there is a fault here.
01:25Gunlakamma Fault.
01:27As you know, there is a river called Gunlakamma here.
01:31So, because Adanki province is very close to that area,
01:35because of this fault, in general,
01:38in the entire Indian continent,
01:41in the north-east direction,
01:44every year, about 5 cm per year, the river moves.
01:51Because of that, some stresses build up internally,
01:55on these faults.
01:57So, in the Gunlakamma Fault here also,
02:00some stress builds up.
02:02After that, because of a little more rainfall,
02:05the energy is released all of a sudden,
02:08in the low-lying areas of the earth.
02:13So, that is called hydrostatic pressure.
02:17So, because of this, we get this sound.
02:22So, what is happening here,
02:25is a phenomenon related to an earthquake swarm.
02:31So, after this 3.1,
02:33all the earthquakes with very low intensity,
02:36this is a very low localized phenomenon.
02:39This localized phenomenon is related to the earthquake swarm.
02:43Another thing is,
02:45what is happening here,
02:48the series produced by the World Meteorological Department,
02:53it was also recorded here earlier.
02:56As you know, in 1967,
02:59the magnitude of the earthquake was 5.4.
03:05Now, even though it is not so intense,
03:08very little energy is released here.
03:11In the middle of that,
03:13even after 1960,
03:15even in 2007,
03:17when this phenomenon happened,
03:19our organization came here.
03:21We established a station in Adyanki Prantham.
03:25Since then, we have been monitoring continuously.
03:29Now, even after the 3.1,
03:31all the small earthquakes are recorded in Adyanki Station.
03:36Similarly, there are more than 1.0.
03:39More than 1.8,
03:41all those with such intensity,
03:43are also recorded in the observatory in Hyderabad.
03:47So, what is all this?
03:49This is an earthquake swarm.
03:52As of now,
03:54this is an earthquake swarm.
03:57This is a process related to the swarm.
04:00So, because of this,
04:02there is a possibility that
04:04such earthquakes will continue for a few days.
04:07That is, with very little energy,
04:09there is a possibility that it will continue for a few days.
04:12As soon as we say earthquake,
04:14we should not be afraid of earthquakes.
04:18First of all, we should not be afraid of earthquakes.
04:21Secondly, we should not be afraid of earthquakes.
04:27We should accept that.
