SAN FRANCISCO - The fourth small earthquake in six days rattled the San Francisco Bay area on Monday, but there were no reports of injuries or damage.
The temblor that struck at 10:07 a.m. had a preliminary magnitude of 2.6 and was centered about three miles northeast of Union City, according to the U.S. Geological Survey. It is considered a "microearthquake" by the USGS.
The quake occurred along the Hayward Fault, which runs underneath the eastern side of the San Francisco Bay and was the site of three other small earthquakes last week.
Two of those quakes had a magnitude of 3.7, and the other had a magnitude of 3.5.
Seismologists said the activity is not unusual for the area and does not necessarily mean the "Big One" will strike soon.

LEWISTON - Residents unnerved by the unexplained deaths of dozens of crows in a neighborhood next to the Promenade Mall hope tests by the U.S. Department of Agriculture will provide some answers.
To residents, it seems almost as though dead crows were falling from the sky. Damien Perreault, 71, said he disposed of 10 dead crows he found on a walk Monday. That didn't count crows dead in the trees.

Six people have died and 60,000 homes have been evacuated in southern Malaysia in the worst flooding in living memory.
But unofficial reports suggest the number of dead may be much higher, the CBC's Jonathan Kent reported Friday.

Animals that hibernate in winter abandoning hibernation: yet another signal that something momentous is happening to the rhythms of the natural world, in the way in which we have always understood them.
It's widely documented that climate change is causing the Greenland and Antarctic ice sheets to shrink. Air temperatures in many parts of the polar regions have increased and waters that surround parts of the ice sheets have warmed up. What most do not know is that until just six years ago, we had no real way of measuring whether the ice sheets were shrinking or growing, or at what rate.
Today, advances in remote sensing, the use of highly sensitive instruments aboard satellites and aircraft, have enabled scientists to examine the mass balance of the ice sheets and to determine just where and how quickly the ice is growing or shrinking. Of particular importance is the mass balance of the ice sheet, which is the difference between how much ice it has lost versus gained over a period of time, and is a direct measure of an ice sheet's contribution to sea level rise.

When the massive tsunami hit the Indian Ocean two years ago and killed nearly a quarter of a million people, Israelis said that was one problem that wouldn't hit them.
But research conducted by Dr. Amos Salamon of the Geological Survey of Israel and colleagues in Italy and the US will report on Thursday that since before the Common Era, there have been two dozen tsunamis documented in the region and 11 on Israel's (illegal) coasts.

Authorities in El Salvador said today they had evacuated 90 people near the Guatemalan border after 193 small earthquakes caused minor damage to homes and widespread panic.
The earthquakes ranged between magnitude 2.3 and 4.3, according to the National Service of Territorial Studies. At least 90 of the tremors were felt by the population.

A series of ash spews has been registered from the crater of the Shiveluch volcano on Russia's Kamchatka Peninsula.
One of the spews reached an altitude of 10 kilometres above the summit, the Kamchatka branch of the Geophysical Service of the Russian Academy of Sciences (RAN) told Itar-Tass on Tuesday.
