Karachi: 32 mild tremors recorded since June 1, says chief meteorologist
Karachi [Pakistan], June 8 (ANI): The port city has been experiencing a series of mild earthquakes for over a week, with 32 tremors recorded since June 1, Geo News reported, citing Chief Meteorologist Amir Haider Laghari's statement. According to Chief Meteorologist Amir Haider Laghari, the earthquakes had magnitudes ranging from 1.5 to 3.6 on the Richter scale. The most recent tremor, recorded on Friday at 8:32 am, had a magnitude of 1.5. The earthquakes have been reported from various areas, including Quaidabad, Gadap, Malir, DHA, and Korangi. The depth of the tremors varied from 2 km to 188 km, as per Geo News. The Pakistan Meteorological Department has confirmed the tremors, with the first recorded earthquake having a magnitude of 2.7 and a depth of 2 km, centered around 20 km south of the defense area. Meanwhile, the second quake was at a depth of 8km and had an epicentre around 7km northwest of Malir. According to Geo News, explaining the reasons behind such continuous tremors, Laghari had earlier told Geo News that the Landhi Fault Line had become active after several decades and is currently going through a normalisation phase. He had said that mild quakes may continue for up to a week due to the gradual release of energy, which helps prevent a major earthquake. The shallow depth of recent quakes makes them more noticeable. The official advised that buildings on fault lines should withstand tremors up to magnitude 6.0. He also noted that the cracks reported in some houses are likely due to structural issues. Another fault line near Thana Bula Khan is contributing to seismic activity. Notably, Pakistan is one of the most seismically active countries in the world, being crossed by several major faults. As a result, earthquakes in Pakistan often occur and are destructive. Pakistan geologically overlaps both the Eurasian and Indian tectonic plates. Balochistan, the Federally Administered Tribal Areas, Khyber Pakhtunkhwa, and Gilgit-Baltistan provinces lie on the southern edge of the Eurasian plate on the Iranian Plateau. Sindh, Punjab, and Pakistan-occupied Jammu and Kashmir provinces lie on the northwestern edge of the Indian plate in South Asia. However, this region is prone to violent earthquakes, as the two tectonic plates collide. (ANI)

Karachi hits 27 tremors in 4 days as 7 more felt
Listen to article A series of mild tremors continued to shake parts of Karachi for the fourth consecutive day on Wednesday, with seismic activity traced to the reactivation of the Landhi fault line, according to officials. Data released by the National Tsunami Center of the meteorological department revealed that 27 earthquakes had been recorded across five locations in the city since Sunday. Though the quakes were of light to moderate intensity on the Richter scale, their shallow depth caused them to be widely felt by residents in several areas. Malir experienced the highest number of tremors, with 11 incidents reported, followed by 11 in Defence Housing Authority (DHA). Three were recorded in Qaidabad, while Korangi and Gadap reported one tremor each.

Tsunami Center Director Amir Haider Laghari said the tremors were the result of underground energy being gradually released along the fault line. 'This slow discharge of energy is a natural process and helps reduce the likelihood of a major earthquake,' he said, noting that the Landhi fault line had become active after remaining dormant for decades. He added that the shallow depth of the tremors was responsible for the strong vibrations felt at the surface. Providing broader context, Dr Adnan Khan, Associate Professor and Geologist at the University of Karachi, told Express Tribune that these were minor tremors and not a cause for alarm. He explained that Karachi is situated on a passive tectonic margin, far from any major fault line, making large, destructive earthquakes highly unlikely in the region. 'These tremors are classified as mild, resulting from minor tectonic movements and stress accumulation deep within the Earth's crust,' Dr Khan stated. He also linked these movements indirectly to Himalayan tectonic activity, where the northward shift of the mountain range—by 4 to 5 cm annually—can generate distant tectonic pressures, occasionally manifesting as low-intensity quakes even in far-off areas like Karachi.

While no loss of life or property damage has been reported so far, experts have warned that the tremors may persist for several more days. Authorities continue to monitor the situation closely and have advised the public to remain alert and follow safety precautions.
