Earthquakes
The 6.0-magnitude earthquake at 10.56 a.m. local time (0256 GMT) was centered less than a kilometer (mile) from the western coast of Dalupiri Island, which is part of the Babuyan Islands in the Luzon Strait north of Luzon island in the Philippines. It struck about 113 kilometers (70 miles) deep, making it an earthquake of intermediate depth, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
There were no immediate reports of damage or casualties from the area, which is mostly uninhabited. The United States Geological Survey (USGS) measured the earthquake at only 5.4 on the Richter scale but at a much shallower depth of just 20 kilometers (12 miles).
The Philippines is on the so-called 'Pacific Ring of Fire', an arc of fault lines circling the Pacific Basin which is prone to frequent and large earthquakes. Volcanic eruptions also occur frequently in the region.
The quake hit 40 kilometres from the border and was centred 34 km (21 miles) NE (44°) from Ensenada, 45 km (28 miles) NNE (25°) from Maneadero, 59 km (36 miles) SSE (155°) from Tecate, and 78 km (49 miles) SE (128°) from Tijuana (all Baja California, Mexico).
The earthquake was recorded at a shallow depth of 11.3 km (7.0 miles). It was followed six hours later by a magnitude 2.6 earth tremor.

Minor tremors were felt for a few seconds at 12:27 p.m. Tuesday. No injuries were reported, and area law enforcement agencies said they didn't receive calls from people calling about the tremors.
A geophysicist with the agency, Julie Dutton, says she doesn't think many people would have felt the earthquake.
The earthquake was centered in Gray Court, about 30 miles south of Greenville.

The U.S. Geological Survey's Earthquake Center confirmed an earthquake with a preliminary magnitude of 3.4 struck about one mile west of Pierre at 2:45 p.m. CDT. There were no immediate reports of damage, but people in the city reported hearing multiple booms and feeling buildings shake.
Eric Stasch, operations manager at U.S. Army Corps of Engineering's Oahe Dam, said an initial check indicated the quake had caused no damage to the massive earthen structure. Officials planned to conduct a more thorough check of the Missouri River dam, located about five miles upstream from Pierre, later Tuesday.
The three motion detectors at the dam were not tripped by the earthquake, Stasch said.

Work continues on the 20-foot sinkhole that formed at Hicks and Dundee roads in Palatine after a torrential rainfall more than two weeks ago.
Fixing the 15-by-20-foot opening at the northwest corner of Hicks and Dundee roads quickly proved complex because of the utilities involved, as well as the discovery of buried bracing material from when the sewer line was originally built, Public Works Director Matt Barry said.
The sinkhole formed July 23 about 30 feet below the surface when a sewer line collapsed in the wake of a torrential downpour - 5.43 inches of rain in three hours.
Barry said he went to the scene Monday and found crews still in the excavating phase, so it's premature to say how much longer repair work will take.
A spokesman for the U.S. Geological Survey said the earthquake occurred about 11:45 p.m. Saturday. No injuries were reported.
Geophysicist Paul Caruso told The Dallas Morning News that the late-night quake was a magnitude 2.6.
The epicenter was six miles west-southwest of Dallas, and it was felt as far away as Greenville, according to reports to the agency's Web site.
Caruso said experts "don't expect significant damage or injuries until the magnitude is in the 5.5 range."

The magnitude 3.1 earthquake struck at 2:16 a.m. in a sparsely populated, mountainous area about eight miles northwest of Grapevine, Calif., and 78 miles northwest of downtown Los Angeles, according to the preliminary report of the quake. There are no reports of damage.
According to the U.S. Geological Survey, a magnitude 2.0 quake hit about 2:34 a.m. Sunday. It was centered about eight miles southeast of Oklahoma and had a depth of 3.1 miles.
The survey reported another earthquake about 8 a.m. located 13 miles northeast of Norman. That quake had a magnitude of 2.3 and also had a depth of 3.1 miles.
Geologists say earthquakes of magnitude 2.5 to 3 are generally the smallest felt by humans.

The current epicenter area can be called as very unusual.
We have NO trace of any historic important earthquakes in the past.
For a lot of people it will be a unique experience.
EMSC reports a magnitude of 4.3 at a depth of 30 km (can be compared as the same intensity as USGS).
