19 tremors in three days shake city
The port city has experienced an unusual spike in seismic activity, with 19 mild earthquakes recorded between June 1 and June 3, according to the National Tsunami Warning Center (NTWC) of Pakistan Meteorological Department. The strongest tremor occurred on Sunday evening, measuring 3.6 on the Richter scale. Data released by the NTWC indicates that the quake struck at 5:33pm on Sunday and was the most intense of the recent seismic events. The weakest tremor, recorded in DHA City, measured 2.1 in magnitude. Officials at the Tsunami Center described the situation as unprecedented, stating that Karachi has never before experienced such a high number of localized tremors within such a short span. "There is no historical precedent for this level of seismic activity in the city," an NTWC official noted, calling the trend "highly unusual." Of the 19 recorded tremors, 11 were centered in District Malir, while others were felt in the southwestern parts of Korangi and the northeastern parts of DHA. Though minor, the frequency has stirred fear among people. Authorities have yet to determine the cause behind the sudden cluster of tremors, but monitoring efforts have been intensified. Seismologists are urging citizens to remain calm while staying alert, as further assessment continues. CM cites concern over pre-shocks While calling low-scale tremors "a good thing" due to the release of the earth's energy, Sindh Chief Minister Murad Ali Shah also warned of the possibility of a major earthquake, citing concerns over pre-shocks that often precede larger seismic events. "I studied earthquake engineering long ago these low-scale tremors are actually a good thing - the earth is releasing its energy," he added. Speaking to reporters after inaugurating a rehabilitation centre for children with physical and neurodevelopmental conditions in Karachi, Shah criticised the decision to evacuate inmates from prison due to the tremors.

No major damage reported after magnitude 5 earthquake near San Diego
A magnitude 5.2 earthquake rattled Southern California on Monday morning, but no major damage or tsunami risk was reported. The earthquake hit around 10:08 a.m. local time and was centered near the town of Julian, California, about 35 miles northwest of San Diego, according to the U.S. Geological Survey. It occurred at a depth of about 8 miles, making it relatively shallow. The National Tsunami Warning Center in Alaska pegged the earthquake's intensity at a slightly higher 5.6 magnitude but said no tsunami is expected. The USGS received reports of moderate shaking around the San Diego and Palm Springs region, as well as light shaking as far away as Los Angeles.

Caribbean earthquake appears on Kentucky seismograph
A 7.6-magnitude earthquake in the Caribbean Sea registered on a seismograph in Hardin County Saturday, the National Weather Service in Louisville reported. The earthquake, which originated north of Honduras and southwest of the Cayman Islands, was detected by a seismograph stationed in Sonora, around 50 miles south of downtown Louisville and roughly 1,500 miles from the approximate location of Saturday's earthquake. A tsunami warning for Puerto Rico and the U.S. Virgin Islands was issued following the quake, but there was no danger to the continental United States, the National Tsunami Warning Center said in a statement Sunday. The tsunami threat later passed. The earthquake Saturday occurred "as the result of strike slip faulting in the shallow crust near the boundary between the North America and Caribbean plates," according to a report from the United States Geological Survey. At least 10 earthquakes with a magnitude of 6.0 or greater have occurred in the last century within 250 kilometers of Saturday's quake. An increase in earthquake activity in the New Madrid Seismic Zone, which includes Western Kentucky, was observed in November and December 2024, according to the Kentucky Geological Survey. There are usually two to four earthquakes a year within the zone, which also includes parts of Arkansas, Missouri and Tennessee.

Tsunami warning canceled for Puerto Rico, Virgin Islands after earthquake in Caribbean Sea
A tsunami warning, issued after a 7.6 magnitude earthquake struck the Caribbean Sea Saturday evening north of Honduras and southwest of the Cayman Islands, was lifted after the tsunami threat passed, the National Tsunami Warning Center said Saturday night. "The tsunami threat has passed," the warning center said in a 9:12 p.m. advisory Saturday. "Unusual currents may be noticed in some areas. Exercise normal caution." At the same time, minutes before the warning was lifted, the center said a tsunami of 1.2 inches was measured on the Yucatan Peninsula in Isla Mujeres, Mexico. "While that sounds small, it's evidence and confirmation that a tsunami is occurring due to a significant earthquake," the agency had said, adding there was no tsunami danger for Puerto Rico, US Virgin Islands, or the continental United States. The warning was issued Saturday evening for the U.S. territories of Puerto Rico and the Virgin Islands after a magnitude 7.6 earthquake occurred at a depth of 10 km in the Caribbean Sea around 6:23 p.m. ET, according to the U.S. Geological Survey. It was the result of "strike slip faulting in the shallow crust near the boundary between the North America and Caribbean plates," USGS said. According to the tsunami warning, sea level fluctuations and strong ocean currents could pose a threat along coasts, beaches, in harbors and in coastal waters. The advisory added "sea level readings are not yet available to confirm or evaluate if a tsunami has been generated" and that the agency will update as more information is available. However, there was no threat to the U.S. Atlantic or Gulf Coast after the quake, the tsunami warning system said. The geological survey said, "large earthquakes at this location of the plate boundary are not unexpected" and earthquakes 6.0 and larger have occurred within 250 km of today's earthquake in the current century." The agency said an earthquake with a similar mechanism measuring 7.5 occurred on January 10, 2018. It caused some damage and a small tsunami, according to USGS. "Luckily, the remote location of these earthquakes limits the potential for significant damage due to shaking," the agency said. This story was updated to add new information after an update by the National Tsunami Warning Center. Saman Shafiq is a trending news reporter for USA TODAY.
