An earthquake with a preliminary magnitude of 6.5 struck early Monday off the coast of Alaska.

The epicenter was about 71 miles east of the village of Chignik, the U.S. Geological Survey reported. The depth was reported at 29 miles deep.

There was no tsunami threat, according to the U.S. Tsunami Warning Center.

Tokyo quake

A powerful magnitude 5.9 earthquake shook the Tokyo area on Thursday night, injuring more than 30 people, damaging underground water pipes and halting trains and subways.

Traffic disruptions continued Friday morning, with local trains delayed and commuters overflowing from stations.

The Meteorological Agency said the quake was centered in Chiba prefecture, just east of Tokyo, at a depth of about 48 miles. There was no danger of a tsunami.

It caused buildings to sway and hanging objects such as signs to swing violently. Chief Cabinet Secretary Hirokazu Matsuno said there were no abnormalities at nuclear power facilities in the area.

Most trains operated Friday morning but with major delays and entry restrictions to avoid overcrowding. There was a long waiting line outside of Shinjuku station in Tokyo, and hundreds of morning commuters were overflowing from the Kawaguchi station.

The Fire and Disaster Management Agency said Friday that 32 people were injured, three of them seriously, from the quake.

Police in Chiba prefecture, where 11 people were injured, said two women in separate locations sprained their ankles when they were thrown to the floor during the quake. A commuter train partially derailed in eastern Tokyo when it made an emergency stop, causing three passengers to fall and get slightly injured, according to the disaster management agency.

20 dead in Pakistan

A predawn earthquake hit southwestern Pakistan on Thursday as most residents slept, leaving at least 20 people dead and damaging hundreds of residential and office buildings, officials said.

The 5.9-magnitude quake, which struck after 3 a.m. local time, inflicted heavy damage on the city of Harnai, in southwestern Balochistan province. After dozens of houses collapsed, hundreds of people were left injured and homeless.

The United States Geological Survey said the quake had a depth of about 5.6 miles, which is considered very shallow and potentially more dangerous because it is closer to the surface. The center of the earthquake was about 60 miles from Quetta, the provincial capital that is near the Afghan border. It is where, in 1935, a 7.7-magnitude earthquake struck, killing up to 60,000 people.

Disaster officials said the death toll from the quake Thursday was expected to rise. The Pakistani military said its troops had reached the area to help with rescue operations. “Army doctors and paramedics, along with necessary medicines, are assisting civil administration for necessary medical care,” the military’s news media wing said in a statement.
