Aardbevingen #16

quote:

Noodtoestand uitgeroepen op Grieks eiland
Op het Griekse eiland Kefalonia, dat gisteren werd opgeschrikt door een aardbeving, is de noodtoestand uitgeroepen. Dat heeft de Civiele Bescherming vandaag meegedeeld.
De aardbeving, die een kracht van 5,8 op de schaal van Richter had, veroorzaakte geen slachtoffers, maar richtte wel materi�le schade aan. Naast beschadigingen aan gebouwen, is er ook sprake van grondverschuivingen, waardoor er schade aan de wegen is. Ook de elektriciteitsvoorziening is onderbroken.

Het epicentrum van de beving bevond zich op zes kilometer van Argostoli, de hoofdplaats van het eiland. Er werden ook een twintigtal naschokken met een magnitude van 4,5 geregistreerd.

6.7-magnitude earthquake strikes off Nicobar Islands - USGS

(Reuters) - A 6.7-magnitude earthquake struck off Nicobar Islands on Friday, the U.S. Geological Service reported.

The quake hit at a relatively shallow depth of 6.2 miles (10 km) about 68 miles (110 km) southeast of Mishap, Nicobar Islands, in the Indian Ocean, the agency said.

Experts in Chile Fear Catastrophe as 300 Quakes Hit in One Week

Chile's northern coast has been hit by more than 300 earthquakes in the past week in what seismologists warned Tuesday could be the precursor to a long-overdue disaster.

Most of these quakes have been too small to be felt on land, but people living near the city of Iquique have experienced the rumbling of up to a dozen tremors per day.

Experts analyzing this flood of data are worried the increased seismic activity could be a sign the region is about to experience its first devastating quake in 137 years. The last event, a magnitude-8.5 quake in 1877, killed thousands of people and created a deadly tsunami that reached Hawaii and Japan.

"It is very unusual activity and we are trying to find out what is causing it," said Mario Pardo, deputy head of the seismology center at the University of Chile.

"We usually get around 10 earthquakes per day in this area [many of them very small], but now we have been getting up to 100 per day," he told NBC News via telephone from the country's capital Tuesday.

Pardo told NBC News that seismologists are particularly concerned about this cluster of quakes because press reports following the 1877 event said there was a similar "swarm" of tremors beforehand.

"We have been waiting for a big one in this area for some time - this is a place where we are expecting an earthquake of over 8.5 magnitude," he said.

Paulina Gonzalez, an expert at the University of Santiago, backed up this analysis. "The latest string of quakes is noteworthy because the last one happened in this seismic zone more than 130 years ago. It's a zone where quakes should happen more often, and they haven’t in a very long time," she told The Associated Press.

New earthquake strikes Nicaragua
(Reuters) - An earthquake struck Nicaragua early on Monday, damaging at least seven houses in and around the capital Managua, but there were no immediate reports of deaths or serious injuries.

The quake follows two others late last week. An official at Nicaragua's seismological authority said that the magnitude was 5.6 and that the shallow depth of its epicenter had caused a greater impact.

The U.S. Geological Survey (USGS) said the quake struck some 6 km (4 miles) northwest of Managua at a depth of 14 km. The USGS registered the quake at magnitude 5.1.

Government spokeswoman Rosario Murillo said there were initial reports of two houses in Managua collapsing and five others in Ciudad Sandino, just outside the capital.

President Daniel Ortega told local radio no deaths had been reported due to the quake because residents had quickly left their homes when it started. He added that some people were reportedly injured, but did not give details of how many.

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.

Seismic earthquake swarm puzzles geologists in Idaho

(Reuters) - Hundreds of low-level and medium-sized earthquakes have struck central Idaho since last month, puzzling geologists who wonder whether the ruptures portend a much larger temblor to come or are merely the rumblings of a seismic fault previously thought to be dormant.

The recent earthquake swarm, beginning on March 24 and climaxed by a 4.9 magnitude tremor on Saturday, has produced no reports of injuries or severe damage but has rattled nerves in a region where Idaho's most powerful known quake, measured at 6.9, killed two children in 1983.

Saturday's earthquake was the strongest recorded in the state since 2005 and was followed on Monday by a magnitude 4.4 event that struck 10 miles north of the small ranching community of Challis, Idaho, according to the U.S. Geological Survey.

The Challis tremor knocked pictures and animal mounts from walls, rattled dishes off tables and was felt by residents in neighboring Montana more than 100 miles from the quake's epicenter, officials said.

The latest seismic surge, including 100 small to moderate quakes on Monday alone, has galvanized government scientists, who planned to install special seismometers in the area as early as Tuesday to more closely track the activity.

The likelihood of a severe earthquake coming on the heels of the recent swarm is low, but much is perplexing about the series of tremors, said Bill Phillips, a geologist with the Idaho Geological Survey at the University of Idaho.

Such earthquake swarms typically are associated with the movement of molten rock below ground, which geologists credited for the recent quake cluster at Yellowstone National Park, or they are linked to an active fault, he said on Tuesday.

"What has many of us scratching our heads is the present-day swarm doesn't appear to be on the big, active fault in the area that ruptured in 1983 and caused the largest earthquake in Idaho," Phillips said.

He was referring to the magnitude 6.9 temblor that struck Mount Borah, Idaho's tallest peak, killing two children in Challis and damaging hundreds of homes and businesses.

Idaho sits at the center of a seismic belt in the intermountain West that runs from northwestern Montana to southern Nevada and contains thousands of faults in the Earth's crust, said Michael Stickney, director of earthquake studies at the Montana Bureau of Mines and Geology.

Carl Alexander, disaster coordinator in Challis, said schools have stepped up earthquake drills, and he has requested that emergency responders in Idaho and Utah be available if disaster strikes.

Alexander is advising local residents to keep bottled water and canned goods on hand just in case "a big shaker" should strike.

"It does make your heart race a little bit to see your windows vibrating," he said of the recent tremors.

Rare earthquake warning issued for Oklahoma

Mile for mile, there are almost as many earthquakes rattling Oklahoma as California this year. This major increase in seismic shaking led to a rare earthquake warning today (May 5) from the U.S. Geological Survey and the Oklahoma Geological Survey.

In a joint statement, the agencies said the risk of a damaging earthquake — one larger than magnitude 5.0 — has significantly increased in central Oklahoma.

Geologists don't know when or where the state's next big earthquake will strike, nor will they put a number on the increased risk. "We haven't seen this before in Oklahoma, so we had some concerns about putting a specific number on the chances of it," Robert Williams, a research geophysicist with the USGS Earthquake Hazards Program in Golden, Colorado, told Live Science. "But we know from other cases around the world that if you have an increasing number of small earthquakes, the chances of a larger one will go up." [Watch 2500+ Oklahoma Earthquakes Since 2012 (Video)]

That's why earthquakes of magnitude 5 and larger are more frequent in states such as California and Alaska, where thousands of smaller temblors hit every year.

This is the first time the USGS has issued an earthquake warning for a state east of the Rockies, Williams said. Such seismic hazard assessments are more typically issued for Western states following large quakes, to warn residents of the risk of damaging aftershocks, he said.

The geological agencies took action after the rate of earthquakes in Oklahoma outpaced that of even California for the first few months of 2014. (California regained the lead in April.)

View galleryRare Earthquake Warning Issued for Oklahoma
Oklahoma earthquakes.
"The rate of earthquakes increased dramatically in March and April," Williams said. "That alerted us to examine this further and put out this advisory statement."

While Oklahoma's buildings can withstand light earthquakes, the damage from a magnitude-5 temblor could be widespread. Oklahoma's last major earthquake was in November 2011, when a magnitude-5.6 earthquake centered near Prague, Oklahoma, destroyed 14 homes and injured at least two people.

"Building owners and government officials should have a special concern for older, unreinforced brick structures, which are vulnerable to serious damage during sufficient shaking," Bill Leith, a USGS senior science adviser for earthquakes and geologic hazards, said in the joint statement.

While scientists haven't ruled out natural causes for the increase, many researchers suspect the deep injection wells used for the disposal of fracking wastewater could be causing the earthquake activity. Fracking, short for hydraulic fracturing, is a method of extracting oil and gas by cracking open underground rock.

Ongoing studies have found a link between Oklahoma's high-volume wastewater injection wells and regions with an uptick in earthquakes.

According to the USGS, the number of quakes magnitude-3 and stronger jumped by 50 percent in the past eight months in Oklahoma. Some 183 earthquakes of magnitude 3 or greater struck between October 2013 and April 14, 2014. The state's long-term average from 1978 to 2008 was only two earthquakes of magnitude 3.0 or larger per year.

If the earthquakes are caused by wastewater injection, then the activity could continue or decrease with future changes in well usage in the state.

"We don't know if this earthquake rate is going to continue," Williams said. "It could go to a higher rate or lower, so the increased chances of a damaging quake could change in the future."

April was een uitzonderlijk actieve maand op het gebied van zware aardbevingen.

Dat blijkt uit een video die het Amerikaanse Pacific Tsunami Warning Center (PTWC) publiek maakte.
Gewoonlijk worden er iedere maand gemiddeld een � twee middelmatige tot zware bevingen geregistreerd. Vorige maand lag dat aantal opvallend hoger. Liefst dertien bevingen met een kracht van 6.5 of hoger op de schaal van Richter schudden de aarde dooreen in april. Het PTWC spreekt van een record. Vijf van de dertien zware aardschokken waren bovendien zo krachtig dat het Centrum achteraf een tsunamiwaarschuwing uitvaardigde.

Op 1 april was het al prijs. Het noorden van Chili werd toen getroffen door een beving met een kracht van 8.2. Bij dat natuurgeweld kwamen zeker zes mensen om. In de weken die volgden werd het land opnieuw door elkaar geschud. Ook de Solomoneilanden, ten oosten van Nieuw-Guinea in de Stille Oceaan, kregen het zwaarder te verduren dan normaal. Op 12 april sloeg daar een beving toe met een kracht van 7.6 op de schaal van Richter. Een dag later werd de eilandengroep getroffen door een nieuwe schok met een kracht van 7.7. Op 19 april beefde de aarde wederom in de regio. De aardschokken eisten meerdere doden en vernielden honderden huizen op de eilanden.

Ook in Nicaragua, Mexico en Canada waren de bevingen in april heftiger dan normaal.

De video hieronder bundelt alle seismische activiteit vanaf begin dit jaar in een animatie. De piek in april is duidelijk zichtbaar op de plattegrond. Het filmpje besluit met een overzichtskaart met daarop alle aardbevingen in heel de wereld van de afgelopen vier maanden, oftewel sinds de start van het jaar.
