Scientists puzzled by recent flurry of quakes in central Idaho
The U.S. Geological Survey has recorded a sequence of quakes rumbling the area, the largest of them being a 4.1-magnitude quake on Thursday, a 4.9 quake on Sunday and a 4.4 on Monday. Smaller quakes have also been recorded, including five on Monday ranging from 2.5 to 3.3 in magnitude. Three of the quakes took place within a 40-minute span starting about 9:12 p.m. Monday. The quakes have ranged from about 6 to 15 miles northwest of Challis in lightly populated Custer County. “People are asking: ‘Is this going to lead to a bigger earthquake?’” said Benz, based in Golden, Colo. “And the answer is we simply don’t know.” He noted the earthquakes are in the same region as Idaho’s largest recorded quake, a 6.9-magnitude in 1983 near Borah Peak, Idaho’s tallest peak at 12,667 feet. Linda Lumpkin, a dispatcher for the Custer County Sheriff’s Office in Challis, said she personally is expecting another big one, but residents in general have become accustomed to the recent temblors.
6.9 magnitude earthquake strikes remote Bouvet Island in South Atlantic
A 6.9 earthquake shook the remote Bouvet Islands in the South Atlantic Ocean Tuesday Morning. Bouvet Island (Norwegian: Bouvetøya, is an uninhabited subantarctic volcanic island and dependency of Norway located in the South Atlantic Ocean at 54°25.8′S 3°22.8′ECoordinates: 54°25.8′S 3°22.8′E. It lies at the southern end of the Mid-Atlantic Ridge and is the most remote island in the world, approximately 2,200 kilometers (1,400 mi) south-southwest of the coast of South Africa and approximately 1,700 kilometers (1,100 mi) north of the Princess Astrid Coast of Queen Maud Land, Antarctica.
Third earthquake strikes Nicaragua in less than a week: fears rampant of ‘big one’
A third earthquake in less than a week struck Nicaragua early on Monday morning, shaking buildings in the capital, Managua, though there were no immediate reports of damage. An official at Nicaragua’s seismological authority said the quake magnitude was 5.6, but its shallow depth had imparted a greater impact. The US Geological Survey (USGS) said the quake struck some 6 km (4 miles) northwest of Managua at a depth of 14 km. The USGS initially registered the quake at magnitude 5.1. Emergency services in Managua were checking for signs of impact, but did not immediately report any damage. Earthquakes also struck Nicaragua on Thursday and Friday last week. The latter, of magnitude 6.6, was felt as far away as El Salvador and Costa Rica.
Note: There are many earthquakes around our planet every day. I just saw these as unusual.
