Karachi was shaken again on Friday morning by two earthquakes, bearing the total number of tremors in six days to 32.
According to Express News, the epicenter of the first earthquake was in the DHA, while the second comes from the district of Malir.
Earlier last night, residents of the colony of Bhains and the surroundings also felt tremors, causing generalized panic. Many residents rushed out of their homes, reciting the Kalma.
Since Sunday, Karachi has witnessed several earthquakes of low intensity in various localities, which dates back concerns among the population.
The director of the National Tsunami Center in the weather department, Ameer Haider Laghari, warned that the Landhi Faille line should remain active for the next few days.
He explained that movements in the underground tectonic layers generate gradually released energy, resulting in these recurring earthquakes.
Earlier, 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 help balance the local flaw line for the 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.
In an interview NewsAmeer Haider Laghari noted that earthquakes come from natural tectonic changes, 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, look for open spaces for a temporary shelter.
Providing a broader 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 as 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.
