Earthquakes

ATHENS (AP) — Authorities say a very strong earthquake with a preliminary magnitude of 6.5 has struck southwestern Greece. At least three people have been injured, and there are reports of a further five people trapped in a collapsed house. Emergency services say two people were slightly injured in the province of Ahaia by a falling roof, and one on the island of Lefkada by falling rocks. It flattened about 70 houses in the provinces of Ahaia and Ilia, severely damaged another 30 and left 230 more with damage and cracks, the Interior Ministry said Monday. The quake also damaged the air traffic control tower at a nearby military airport.

JIANGYOU, China (AP) -- A "relatively strong" aftershock shook a massive quake-formed lake Sunday that had been threatening to flood more than a million people, sending landslides tumbling down surrounding mountains, a state news agency reported. The effect of the 20-second quake on the Tangjiashan lake was not immediately known, Xinhua News Agency said. The dam of unstable mud and rocks was under surveillance following the aftershock. The Tangjiashan lake, created when a landslide dammed the Tongkou River, has become a priority for a government working to head off another catastrophe even as it cares for millions left homeless from the May 12 quake that killed nearly 70,000 people.

RENO, Nevada (AP) -- A months-long swarm of earthquakes picked up again Sunday as a string of minor temblors rattled Reno, Nevada, causing downtown high-rises to sway and knocking items off walls and shelves. There were no immediate reports of injuries or major property damage after about 20 minor quakes reported on the western edge of Reno over 12 hours ending about noon. Magnitude-3.9 and 3.6 quakes struck within a couple minutes of each other shortly before 11 a.m. and were preceded by 3.2 and 3.0 quakes early Sunday, said researchers at the seismological laboratory at the University of Nevada, Reno. The swarm, which has produced thousands of mostly minor quakes, had prompted some residents in the densely populated quake zone to spend nights outside in campers and trucks. Nevada is the third most seismically active state in the U.S. behind California and Alaska.
