Peru rattled by 4.9 magnitude earthquake - kills at least 8

© Weatherchannel.com


The small farming town of Misca was rattled by a magnitude 4.9 earthquake Sunday.
At least eight people are dead and four are missing after a shallow 4.9-magnitude earthquake rocked a remote village in Peru on Sunday, according to Dia Correo. Most of the victims were killed after their crudely constructed homes collapsed, the Associated Press reports.

The quake was centered 25 miles southeast of Cuzco in the farming town of Misca in the Paruro region and was a relatively shallow five miles deep.

Spanish-Language news site El Comercio reports that four of the dead are children, including a three-month-old baby. Landslides in the area have made it difficult for rescue personnel to reach those affected.

El Comercio reports that nearly 45% of the homes in the village have been destroyed and power has been knocked out. Displaced residents were moved to a local soccer field for safety, according to RPP Noticias.

Ups and downs: 2013's natural disasters in review

earth changes
According to the "Annual Disaster Statistical Review 2013" published this month by the Centre for Research on the Epidemiology of Disasters (CRED), 2013 is a year with 330 registered natural disasters. This is less than the average annual disaster frequency observed from 2003 to 2012 which is 388, and represents a decrease in associated human impacts of disasters which were, in 2013, at their lowest level in last 16 years.

The death toll of natural disasters still killed a significant number of people totaling to 21,610 but this is largely below the annual average between 2003-2012 which is 106,654.

96.5 million people became victims worldwide, which was also below the 2003-2012 annual average of 216 million. On the side of the economy, economic damages from natural disasters shows, in 2013, a decrease to average levels, 2013 US$ 156.7billion, with estimates placing the costs at US$ 118.6 billion.

Trends in occurrence and victims (deaths and affected)
For the last decade, China, the United States, Indonesia, the Philippines and India constitute together the top 5 countries that are most frequently hit by natural disasters.

In 2013, China experienced its highest number of natural disasters of the last decade. The country was affected by a variety of disaster types, including 17 floods and landslides, 15 storms, 7 earthquakes and one mass movement of geological origin, one drought and one period of extreme temperature.

Comment: In sum, 2013 saw fewer disasters, deaths, victims and economic damages on the whole. However, it saw isolated instances of record-breaking disasters, while floods and storms were responsible for the worst damage in terms of people affected. China and the U.S. continue to be hit the hardest, with China enduring its highest number of disasters in the last decade.

As Pierre Lescaudron describes in his book, Earth Changes and the Human-Cosmic Connection, this apparent decrease in disasters is probably due to an overall decrease in the Earth's electric field (due to a solar-companion-induced drop in the Sun's activity) and an increase in the conductivity of that field (due to the increase in comet dust entering our atmosphere). The result: more frequent, smaller storms (hurricanes, tornadoes, lightning, etc.). This will show up in the statistics as a drop in major natural disasters, but as we can see around us, it doesn't say much about the continued crazy weather the planet has been experiencing the last couple years.

It's the time for floods and storms to do their damage, while cosmically-induced processes perhaps build up for some future, major disasters. Think Chelyabinsk. Think Ebola.

Magnitude 5.0 earthquake jolts Catanduane, Philippines

The Provincial Disaster Risk Reduction and Management Council (PDRRMC) has yet to receive a report regarding possible damage from the magnitude 5.0 earthquake that shook Catanduanes 12:16 a.m. Saturday. PDRRMC in-charge Jerry Beo told the Philippine Daily Inquirer that he has yet to establish communications with local officials in Gigmoto town where the epicenter was located.

The United States Geological Survey (USGS) calculated the epicenter of the quake to be in the vicinity of Barangay (village) Dororian at 13.719 degree north and 124.384 degree east, or around six kilometers south of Gigmoto proper. The island province of Catanduanes is just 200 kilometers west of the Philippine Trench, which has generated large earthquakes in the past.

In the capital town of Virac, many people were roused from their sleep by the earthquake, which they say was preceded by a humming sound. According to subdivision residents Guillermo Castilla and Leo Austero, the shaking was strong enough for them to hear creaking and groaning sounds coming from their houses.

The USGS said earthquakes of this magnitude usually have aftershocks, with the secondary shock waves usually less violent but could be strong enough to do additional damage to weakened structures and may occur in the first hours, days, weeks or even months after the quake.

Update - Mammoth Lakes earthquakes now exceed 1059 in latest seismic swarm

The Long Valley Caldera is experiencing a large seismic swarm. As magma moves through the earth, it displaces and fractures rock along the way. This movement causes earthquakes that can be recorded with seismometers at the surface of the earth. Seismic monitoring is the most used technique for volcano surveillance. Volcanic earthquakes often provide the initial sign of volcanic unrest. Their signals differ from typical, tectonic, earthquakes because they tend to be found at depths shallower than 10 km, are small in magnitude (< 3), occur in swarms, and are restricted to the area beneath a volcano. Harmonic tremor, or volcanic tremor, is the name for the continuous, rhythmic seismic energy associated with underground magma movement. At Long Valley Caldera, there are currently 61 seismometers that make up the seismic network used to determine earthquake location and energy of movement with time.
The first instrument was installed in 1974 and additional instruments were added throughout the 1980s and 1990s. Between 2000 and 2003, the seismic network was updated to include additional, more modern instruments. More than 200 more earthquakes have erupted in the area in a 24 hour period. Additionally, some earthquakes were now reported at shallower depths. Rodger Wilson, who is following this area for tens of years, hasn't seen this activity since the 1990′s! We have the impression however that the frequency of the earthquakes has seriously declined the last couple of hours. The seismicity at Mammoth Lakes California has even increased compared to this morning. Below all earthquake epicenters during the last 24 hours. Depth of the hypocenters still at +10 km. Earthquake swarms are a regular phenomenon at Long Valley but nobody knows where the magma will move next. We will have to wait and see if this latest swarm indicates a massive movement of magma and might be an early-warning sign that Long Valley might be moving towards an eruption. The last eruption at the volcano is said to have occurred 700,000 years ago and is long over-due. - ER, USGS, TEP

Nearly 3 dozen small quakes in 24 hours - Volcanic unrest at Mammoth Lakes?

In this 2012 photo, runners take to a trail in the Mammoth Lakes region in California's Eastern Sierra.
Nearly three dozen earthquakes have rattled the Mammoth Lakes region in less than 24 hours as the area continues to experience ripple effects of "volcanic unrest," according to the U.S. Geological Survey. The temblors -- all between magnitude 2.5 and 3.8 -- have struck since 9 a.m. Thursday, with the latest recorded at 1:49 a.m. Friday, according to the USGS. The 3.8-quake occurred at 9:21 p.m. with an epicenter six miles from Mammoth Lakes.

Heightened earthquake and ground uplift activity have been measured at Mammoth Mountain and the Long Valley Caldera over the last few decades. At 11,053 feet, Mammoth Mountain in California's Eastern Sierra is a lava dome complex on the southwest rim of Long Valley Caldera, although eruptions haven't occurred for some 57,000 years. The recent swarm of quakes in and around the mountain is being tied to recent "volcanic unrest" marked by gas emissions, tree die-offs and intrusions of upward-moving sheets of rock, according to the USGS.

Fukushima, Japan rocked by two earthquakes in one hour; epicenter near nuclear plants

A pair of moderate earthquakes struck just off the coast of Japan's Fukushima Prefecture Wednesday, close to the nuclear power plants crippled by the March 2011 tsunami. There were no early reports of damage, injuries, or new problems at the nuclear plants. The Japan Meteorological Agency says the first earthquake struck at 9:45 p.m. JST (8:45 a.m. EDT in the U.S.) and registered a magnitude of 5.0. The second quake, a slightly stronger magnitude-5.2 tremor, struck 46 minutes later. Both were centered just off the coast of Fukushima Prefecture, where the Fukushima Daiichi and Fukushimi Daini reactors were severely damaged in the March 11, 2011 tsunami that followed a magnitude-9.0 quake farther offshore.

The damage spawned the worst crisis at a nuclear power plant since the Chernobyl disaster in 1986, and prompted Japan to shut down most of its nuclear power plants. Tokyo Electric Power Company (TEPCO) has been working to contain radioactive materials in the years since. TEPCO said there were no new abnormalities caused by Wednesday's quakes, nor any changes to radioactivity levels at the monitoring post there, according to public broadcaster NHK. The company said there were no reported abnormalities at its Tokai Daini nuclear power plant, farther south along the coast of Ibaraki Prefecture. The plant has been shut down since 2011.

Comment: There has been a lot of seismic activity lately. See the following Sott Worldview map of recorded earthquakes in the past month alone:

Sweden earthquake 'was strongest in 100 years'

Sweden earthquake

This graph shows the moment of impact in Hassela, which is 13 kilometres from the earthquake's epicentre.
An earthquake measuring 4.1 on the Richter scale shook parts of central Sweden on Monday and experts have revealed it was the strongest in a century.

The quake hit in the afternoon between the towns of Mora and Sveg.

"There was a bloody great bang, it was like a bomb," Åke Hedman near Ljusdal told the Aftonbladet newspaper. "It was as if there was a lightning bolt directly above me - only ten times worse," the 57-year-old added.

Björn Lund, a seismologist at Uppsala University, said the earthquake is the strongest Sweden has seen since 1904 when an area by the Koster islands was hit by an earthquake measuring 5.5 on the scale.
