QUETTA, Pakistan – A major earthquake hit a remote part of western Pakistan on Tuesday, killing at least 45 people and prompting a new island to rise from the sea just off the country's southern coast. Tremors were felt as far away as the Indian capital of New Delhi, hundreds of miles (kilometers) to the east, where buildings shook, as well as the sprawling port city of Karachi in Pakistan. The United States Geological Survey said the 7.8 magnitude quake struck 145 miles (235 km) southeast of Dalbandin in Pakistan's quake-prone province of Baluchistan, which borders Iran. The earthquake was so powerful that it caused the seabed to rise and create a small, mountain-like island about 600 meters (yards) off Pakistan's Gwadar coastline in the Arabian Sea. Television channels showed images of a stretch of rocky terrain rising above the sea level, with a crowd of bewildered people gathering on the shore to witness the rare phenomenon. Officials said scores of mud houses were destroyed by aftershocks in the thinly populated mountainous area near the quake epicenter in Baluchistan, a huge barren province of deserts and rugged mountains. Abdul Qadoos, deputy speaker of the Balochistan assembly, told Reuters that at least 30 percent of houses in the impoverished Awaran district had caved in. The local deputy commissioner in Awaran, Abdul Rasheed Gogazai, and the spokesman of Pakistan's Frontier Corps involved in the rescue effort said at least 45 people had been killed. In the regional capital of Quetta, officials said some areas appeared to be badly damaged but it was hard to assess the impact quickly because the locations were so remote. Chief secretary Babar Yaqoob said earlier that 25 people had been injured and that the death toll was expected to increase as many people appeared to be trapped inside their collapsed homes. Local television reported that helicopters carrying relief supplies had been dispatched to the affected area. The army said it had deployed 200 troops to help deal with the disaster. The provincial government declared an emergency in Awaran and the military mobilised medical teams as well as 200 soldiers and paramilitary troops to help with the immediate relief effort. “We have received reports that many homes in Awaran district have collapsed. We fear many deaths,” Jan Muhammad Baledi, a spokesman for the Balochistan government, said on the ARY news channel. “There are not many doctors in the area but we are trying to provide maximum facilities in the affected areas.” Television footage showed collapsed houses, caved-in roofs and people sitting in the open air outside their homes, the rubble of mud and bricks scattered around them. Abdul Qudoos Bizinjo, deputy speaker of Balochistan's parliament, told Dunya TV there were reports of “heavy losses” in Awaran. Damage to the mobile phone network was hampering communications in the area, he said. Awaran district has an estimated population of around 300,000, scattered over an area of more than 21,000 square kilometres (8,000 square miles). Tremors were felt as far away as the Indian capital and even Dubai in the Gulf, while office workers in the Indian city of Ahmedabad near the border with Pakistan ran out of buildings and into the street in panic. In April a 7.8-magnitude quake centred in southeast Iran, close to the border with Baluchistan, killed 41 people and affected more than 12,000 on the Pakistan side of the border. The Red Crescent in Tehran reported no damage from the latest quake. Office workers in Pakistan's largest city Karachi rushed out of their buildings. “My work table jerked a bit and again and I impulsively rushed outside,” said Noor Jabeen, 28. “It was not so intense but it was terrible,” said Owais Khan, who works for a provincial government office. “Whenever I feel jolts it reminds me of the 2005 earthquake in Kashmir,” said Amjad Ali, 45, an IT official standing in the street. The 7.6 magnitude quake in 2005 centred in Kashmir killed at least 73,000 people and left several million homeless in one of the worst natural disasters to hit Pakistan. Balochistan, Pakistan's largest but least populous province, is believed to have substantial gas and oil reserves, but it is violent and unstable. – Agencies
