In total, 19 light earthquakes have been recorded since Sunday evening, an unprecedented event in the history of Karachi City.
The early tsunami alert cell Karachi has published official data, confirming that the strongest earthquake was 3.6, while the weakest was recorded at 2.1 magnitude.
Among these, 11 tremors were recorded in the District of Malir, while the others were felt in the southwest part of Korangi and in the northeast regions of DHA.
Experts attribute repeated seismic activity to changes in underground tectonic layers. These tremors are caused by the liberation of energy generated by the seismic movement of low level below the surface of the earth.
In response, residents of several streets and districts of Malir and Quaidabad chose to stay outside, to set up temporary shelters and tents in open areas. Women gathered on Monday to recite the Holy Quran, praying for security.
Commissioner Karachi Syed Hassan Naqvi urged residents to stay calm and not to believe in rumors circulating on social networks.

According to the National Tsunami Center (Pakistan Meteorological Department), these tremors are not a sign of warning for a major natural disaster, but rather a natural geological process. This activity can actually help balance the local flaw line for years to come.
Ameer Haider Laghari, head of the National Tsunami Center, explained that the quidabad flaw line remains active and that the situation could continue up to a week.
The first earthquake of the year in Karachi was recorded on March 31, recording 4.7 magnitude with a depth of 19 kilometers. On the other hand, this last sequence has shown a coherent scheme, in particular in Malir and Quaidabad, where nine earthquakes of low intensity to moderate occurred in two days. Several parts of the city felt the tremors.
Chronological details of seismic events include:
-
Sunday, 5:33 p.m. – Maîtrude 3.6, depth 10 km, epicenter: Qaidabad
-
Sunday, 10:29 p.m. – Ambalization 3.2, depth 10 km, epicenter: qaidabad
-
Sunday, 11:45 p.m. – 3.1 AMBALLAGE, Depth 10 km, epicenter: 40 km south -east of Malir
-
Monday, 1 h 06 – Ambalization 3.2, depth 12 km, epicenter: City of Gadap
-
Monday, 11:04 am – Maîtrude 3.2, Epicentre: Qaidabad
-
Monday, 12:17 pm – Maîtrude 2.2, depth 29 km, epicenter: Southeast Malir
-
Monday, 1:11 p.m. – Maitritude 2.4, depth 188 km, epicenter: 11 km east of Malir
-
Monday, 1:38 p.m. – Ambalization 2.9, depth 5 km, epicenter: near Dha
-
Monday, 9:49 p.m. – 3.0 -legged outpar, depth 13 km, epicenter: 30 km east of Dha
In an interview NewsAmeer Haider Laghari noted that earthquakes come from natural tectonic offsets, where the energy accumulated on earth is gradually released – causing seismic activity. He stressed that this is a global geological process, occurring in certain regions more frequently than others.
He recalled similar tremors in northern Pakistan, where the activation of a flaw line triggered panic in Islamabad and in neighboring areas for several days.

Laghari assured that Karachi earthquakes are of low intensity, and each subsequent tremor was less intense than the previous one. He also clarified that these are not replicas, because these minor earthquakes generally do not produce replicas – these are independent seismic events.
He warned that Malir, Quaidabad and the surroundings could continue to feel tremors for two more days for a week. Pakistan is in a shallow earthquake area, which means that most earthquakes occur at low depths.
He also highlighted other fault lines active in the region, including the Landhi Faille line, Thana Bula Khan and the Faille line of the Kirthar Kirthar beach plaque foundry.
As a precaution, he informed that residents of structurally weak buildings should evacuate quickly during the tremors. People must avoid standing near the walls and instead, are looking for open spaces for a temporary shelter.
Offering a wider context, Dr. Adnan Khan, associate professor and geologist at the University of Karachi, said EXPRESSION that these are minor tremors and not a cause of alarm.
He explained that Karachi is located on a passive tectonic margin, far from any major flaw line, which makes large earthquakes very improbable in the region.
“These tremors are classified as light, resulting from minor tectonic movements and stress accumulation deep in the earth’s crust,” said Dr. Khan.

He also linked these movements indirectly to the Himalayan tectonic activity, where the gap towards the north of the mountain chain – from 4 to 5 cm per year – can generate distant tectonic pressures, sometimes manifesting itself like earthquakes of low intensity even in distant areas like Karachi.
Dr. Khan also highlighted human factors that can play a subtle role in the modification of underground stability, in particular the incineration of industrial waste and excessive extraction of groundwater, which can both influence local seismic behavior over time.
Although the scientific consensus remains that these tremors are harmless, Laghari and Dr.Khan stressed the importance of awareness of basic security.
Dr. Khan also advised citizens to stay calm during any tremor tremor and immediately move to open areas, remaining away from walls, foundations or large structures.
Meanwhile, at least 216 prisoners escaped from the Malir district prison in Karachi on Monday evening after earthquakes led to a temporary evacuation of the detainees, confirmed the Superintendent of Arshad Shah prison on Tuesday.
According to Shah, the prisoners exploited the confusion during the evacuation to flee. In response, the security forces, including the police, the rangers and the body front (FC), were quickly deployed to guarantee prison and prevent other escapes.
The Sindh Inspector General Ghulam Nabi Memon reported that 78 of the escapees had been resumed, while a major research operation is underway to find the remaining fugitives.
The safety of the establishment has since been tightened, the rangers taking care of the perimeter and the police strengthening security inside the prison.
