El terremoto durante la Navidad tuvo un inicio extremadamente rápido, pero perdió su fuerza durante los primeros 8 segundos, deteniéndose justo 10 segundos después. Esto salvó a Chile de sufrir un terremoto inmenso, pero, sin embargo, es una noticia preocupante para los sistemas de Advertencia Sísmica Temprana.

Why have there been so many large earthquakes in Ecuador so close together in time? A team of geophysicists aims to answer that question.
A M=7.0 earthquake shook off the coast of Fiji yesterday, and possibly triggered a remote aftershock over 1,000 km away.

Almost anywhere else in the world, a M=7.7 earthquake would be considered large and rare, but today’s shock is exceptional
In last month’s M=7.8 Kaikoura, New Zealand earthquake, at least 9 separate faults ruptured in the largest quake in New Zealand since the 1855 M=8.2-8.3 Wairarapa earthquake.
Thursday’s M=6.5 earthquake should have increased the stress on the Mendocino Fault Zone west and east of the rupture zone. These stress increases nominally would have the potential to trigger more earthquakes.
The European Space Agency (ESA) recently released new satellite imagery, that reveals which parts of the Bay Area are subsiding and those that are being uplifted.

In our judgment, the Norcia, Gorzano, Capitignano Faults could now be the next domino pieces to fall.
A M=5.5 shock preceded the M=6.1 earthquake by little over 2 hours, and so might be deemed a foreshock. After the Amatrice earthquake, the INGV posted a calculation of the stress transferred from the M=6.2 to surrounding faults.
It is likely that earthquakes in 1943 and 2000 contributed stress that brought the fault which ruptured today, closer to failure.
October 20th marks the 9th official Great ShakeOut earthquake drill.

The California Office of Emergency Services (CalOES) issued an advisory stating the recent earthquake swam may have slightly increased the probability of additional earthquakes over the next week.
When large earthquakes strike, media outlets flock to the scene to cover devastation. However, we rarely get a glimpse of how areas or people are doing months or even years after an event.

The earthquake stuck at a relatively shallow depth of 5-7 km (3-4 mi) and was felt over an area about 100 km (60 mi) wide; the closest town is Oliver, 15 km to the west, where it was strongly felt.
Answer: They are the ‘one percent.’
At 5:02 Saturday morning, a Magnitude 5.6 earthquake struck 14km NW of Pawnee, Oklahoma. This was a fairly shallow quake occurring about 6.59 km below Earth’s surface, and it caused strong shaking.
Based on early reports, the USGS estimates that there will be no casualties or major damage. However, some injuries or economic losses may still be possible.
熊本での地震続発を報告してから４ヵ月が経過しました．本年４月14日に発生した最初のM6.5地震から28時間後の16日には，同じ断層帯でM7.3地震が発生しました．この地震で，熊本市，益城町，西原村，南阿蘇村など，日奈久断層帯，布田川断層帯に沿った地域で甚大な被害がもたらされました．以下では，これまで得られたいくつかの知見を紹介します．
It’s been over four months since we wrote about the powerful Kumamoto quake sequence: The 15 April 2016 Mw=6.2 (Mjma 6.5) Kumamoto, Japan, shock, which was succeeded 28 hours later by the very damaging Mw=7.0 (Mjma 7.3) shock on the same fault system. We can now give you a preview of crucial new discoveries by Japanese and other researchers.
At 4:37 am Friday morning, a M=7.1 earthquake struck off the east coast of New Zealand, 166 km northeast of Gisborne. This was a moderately deep quake, occurring about 20 km below Earth’s surface, and it caused moderate to strong shaking on land.
Last week’s M=6.2 Italy earthquake left many parts of the medieval city of Amatrice in ruin. In the old part of the city, most buildings were made of unreinforced masonry, leaving them susceptible to collapse [Guidoboni and Valensise, 2015]. Amatrice was all but destroyed in three large shocks over 19 days in 1703, and so the part of the town that was highly damaged on 24 August 2016 was composed of buildings largely constructed about 300 years ago. In contrast, the newer construction in the east side of the town came through the M=6.2 quake relatively unscathed.
Could this happen again now? As with precursory swarms, progressive earthquake sequences are uncommon.

The M=6.2 Italy earthquake dominated the seismic headlines today, but an even larger quake just a few hours later was largely ignored. While unrelated, both earthquakes are important. Today’s magnitude 6.8 earthquake struck western Burma, 200 km northwest of the capital city of Naypyitaw.
Today’s earthquake, 10 km southeast of Norcia, has a shallow depth of 10 km, and lies in the Central Apennines normal faulting system. It was felt from Rome to Bologna. One can see from the Temblor map that quakes of this size are expected one or two times in a lifetime at Norcia.
