Extremely dangerous earthquake in Nagano, Honshu, Japan – At least 20 injured
Last update: November 22, 2014 at 5:41 pm by By Armand Vervaeck
Update 17:20 UTC : The number of injured has increased to 20
Update 16:43 UTC : In the 16:23 update we did talk about a Thrust type earthqauke. This was confirmed by the following report : In Joetsu, the road has been lifted about 50cm (Kiyosato District Kaminakajo district)
Update 16: 39 UTC : The latest reports are mentioning 11 injured
Update 16:23 UTC : The damage looks rather limited if we take the strong Magnitude into consideration. One of the main reasons is the earthquake type. Based on the USGS beach-ball below we are looking at a thrust focal mechanism (2 plates pushing towards each other. The resulting movements are far less dangerous than transform earthquakes (the type which hit China today). An additional reason to have weaken the shaking is the location it occurred, the rocky Japanese Alps. This kind of underground does not transmit the earthquake waves like it would be the case in for example a sediment valley.
Update 16:12 UTC : As we are after midnight in Japan, rescue operations take more time. In some parts of the epicenter area the power is down. There are also reports of broken water pipes, a ruptured fuel tank leaking 1000 liter of oil. Collapsed walls etc. It will take at least 5 to 6 hours (early morning) before we will get a good picture of the damage.
Update 16:01 UTC : So far at least 4 people injured
Update 14:38 UTC : As could be expected, multiple landslides have been notices (these are the Japanese Alps). One of these landslides is blocking the Shirasawa tunnel who links Nagano with Hakuba
Important Update 14:27 UTC : Several buildings collapsed and people possibly buried in Nagano Prefecture. (Source NHK Japan) Update : 4 houses should have been collapsed. No further news at the moment.
Update 14:17 UTC : The Nagano Fire Department is reporting several injuries and a building collapse after 6.8 quake this evening.
Update 14:13 UTC : Kyodo News Reports that Hakuba Village (famous for the 98 olympics) has seen a building collapse.
Update 14:11 UTC : Image of a convenience store in Nagano
Update 14:06 UTC : The city of Nagano has not sustained damage so far (this would be seen almost immediately). Power is still on in Nagano based on the webcam we are looking at. So far we have reports of 2 people who have been injured in Hakuba (ambulance under way).
Update 14:01 UTC : Below the theoretical shaking map of USGS based on a M6.2 Magnitude (JMA Japan reports M6.8)
Update 13:51 UTC : The Nagano prefecture authority has reported that the Kashiwazaki-Kariwa nuclear power plant sustained NO damage but has been shut down as a precautionary measure.
Update 13:47 UTC : Shaking of the Nagano earthquake (ni mention of distance from the epicenter)
Update 13:43 UTC : until now only reports from items falling from shelves. No structural damage so far (too soon to be final of course) (thx to @RobertSpeta living in Japan)
Update 13:37 UTC : Prof. Max Wyss who specializes in theoretical calculations of injured and fatalities based on many parameters expect for this earthquake 0 to 10 fatalities and 0 to 100 injured. He has used the GFZ data (M6.2 at 10 km for his calculations).
Update 13:31 UTC : We expect the whole Nagano prefecture at risk for damage and injuries.
Update 13:30 UTC : EMSC and USGS are reporting a M6.2 Magnitude bur JMA Japan maintains his M6.8 Magnitude at 10 km.
Update 13:24 UTC : Shaking values who may lead to damage. Landslides are almost a certainty! Of course NO tsunami risk because the earthquake happened below mainland Honshu
Update 13:22 UTC : JMA Japan has a theoretical shaking of -6 We at Earthquake-report.com consider 5+ already as probably damaging. The earthquake happened at a shallow depth below Eastern Honshu

Dangerous damaging earthquake in Sichuan, China (Xinduqiao most at risk) – at least 2 people killed and 48 injured
Last update: November 22, 2014 at 5:21 pm by By Armand Vervaeck
Update 16:54 UTC : The earthquake toll has further increased to 2 people killed and 48 injured
Important update 15:03 UTC : The current status is 1 person killed and 22 injured. A lot of relief material has been sent to the hardest hit areas. We expect this number to increase in the following hours.
Update 12:10 UTC : Below the shaking map published by the Chinese Seismological agency. To be noticed a far great strong shaking area than the USGS (M5.8) map below.
Update 11:55 UTC : Apparently there are NO big buildings collapsed, neither in Xinduqiao nor in Tagong, which is very good news. No images yet from the epicenter area. We expect also landslides to have occurred as this is a mountainous area.
Below the seismic map of the greater epicenter area. Combined with the beach-ball below and the faults on this seismic map, we can now say that the ground movement went from South-East to North-West
Update 11:21 UTC : Beijing News reported that in Xinduqiao town residents said that many houses collapsed, mostly older Tibetan houses, more recently build houses have only been damaged. Currently, NO no rescue personnel arrived as yet, some areas have still electricity, communications are on and off.
Update 11:18 UTC : The earthquake was even felt as far as Chongqing
Update 11:14 UTC : Some walls of Kangding Airport are showing cracks. 3 trains lines are delayed because the railway personnel has first to inspect the rails.
Update 11:10 UTC : Unconfirmed reports are mentioning that one 73 year old man from Kangding was killed due to the earthquake. The exact reason has not been reported.
Update 10:59 UTC : People living in the wider earthquake area (including Kangding) are on the streets and are afraid to go inside again.
Update 10:56 UTC : Medical teams have been sent to the epicenter area. China has probably the best managed earthquake response teams in the world. Part of the response is by the Chinese Army. A lot of specialized material can be put into work within 24 hours (heavy material, telecommunications, field hospitals, etc etc)
Update 10:23 UTC : The first reports from the biggest nearby city Kangding are hopeful. No widespread collapses houses and only 1 injured person because of broken glass. Specialized teams are now rushing to the villages closest to the epicenter. We keep you informed when new reports are coming in. The earthquake was strongly felt in Kangding (39 km from the epicenter)
Update 10:13 UTC : The earthquake was felt strongly in Chengdu (based on Chinese readers reports). Chengdu is the capital of Sichuan province. The Chengdu districy has a population of 16 million. Chengdu itself is however not an important risk for this earthquake.
Update 09:59 UTC : ER calls the below village as most in danger as it is located closest to the epicenter (approx. 6 km). The epicenter (breaking itself is located on the edges of the high mountain chain (which is normally good news).
Update 09:50 UTC : Further bad news for this earthquake. The beach-ball shows a strike-slip earthquake type, the most dangerous one with a mainly horizontal movement. Older houses and buildings can be severely damaged by this type of earthquake.
Update 09:43 UTC : Below the map as reported by the Chinese Seismological Agency. The upper dot is today’s epicenter, the lower dots other +M5 earthquakes this year. important to say about this map is that the earthquake is NOT an aftershock but a mainshock.
Update 09:37 UTC : The Chinese authorities are reporting a Magnitude of 6.3 at a depth of 18 km. These data are confirming our earlier expectations. Damage and injuries almost certain, hopefully no fatalities.
Update 09:25 UTC : Prof. Max Wyss who specializes in theoretical calculations of injured and fatalities based on many parameters expect for this earthquake 0 to 200 fatalities and 50 to 500 injured. Let’s hope that he is wrong this time or that only his minimum values will be reached.

Update November 16 : Based on our research, 9 people have been injured by this earthquake
Update : The northern part of Sulawesi has got his part of the damage. Collapsed walls and cracks in walls have been reported in Manado
Update : As could be expected a lot of aftershocks are raging in the area, most of them luckily far out of the coast
Update : Below the spectacular Geofon seismogram as recorded in Sulawesi
Update : Following the theoretical data from USGS, a maximum shaking of MMI V (moderate shaking) was expected from this earthquake.

Update 14:24 UTC : We expect the city of Qotbabad to be in the damage zone (radius 20 km from the epicenter)
Update 14:20 UTC : the population density in this desert area is very low and thus only 2700 people can be affected by this dangerous earthquake (radius 20 km). In this area we think that slight damage will be likely

Dangerous earthquake in Northern Ecuador (border with Colombia)
Last update: October 21, 2014 at 8:56 am by By Armand Vervaeck
Update : Although we mentioned earlier that this earthquake was not linked to volcanic activity, the Carchi authorities have now confirmed that the earthquake was volcanically triggered.
Important update : INGEOMINAS has raised the alert level of the Chiles – Cerro Negrp volcanoes from yellow to orange at these long-dormant, twin volcanoes as seismicity has surged (over 1500 events!) over the past 24 hours (including a magnitude M5.6 earthquake).
Update : One house was apparently damaged in the capital of Carchi province, Tulcan. No more reports about the fear for a missing person in the landslide. Let’s hope that this was a false alert.
Update : Picture below shows a landslide due to this earthquake (image courtesy Army Ecuador). The governor of the Crachi province in Ecuador may decide to suspend the classes in some schools.
Update : No reports of damage so far, only an Ecuadorian official report of 1 person missing after a landslide in Cerro Negro.
Update : IGEPN (Ecuador) mentions a Magnitude (Richter) of M5.9 at a depth of 6 km only. Although no direct volcanic link was reported, the epicenter was located in the direct vicinity of the border Colombian volcanoes Cumbal and Chiles.

Final Update : As expected by ER NO structural damage has been detected but a lot of in-house, in-office etc damage like collapsed ceilings, fallen hanging objects, products fallen from shelves etc. Reason : the deep hypocenter. If shallower, structural damage may have been caused.
Are you one of the people who felt the shaking of this earthquake AND/OR are you aware of any damage (at your place or elsewhere)? If yes, may we kindly request you to let us know what you have felt and if you have damage or not. Please use the form below.
Update 18:40 UTC : Below the first damage pic from Alaska. Bill Falsey will not be the only one posting such images.
Update 18:25 UTC : The theoretical Pager expects a MMI VI strong shaking (updated) for the Anchorage area, which reflects better what we receive as IHFI reports.
Update 18:09 UTC : Based on the first received experience reports we fear that slight damage will be possible. Max. theoretical shaking should be MMI V (moderate shaking). Moderate shaking is mostly harmless.
Update 18:07 UTC : ER is not expecting any damage from this earthquake mainly for 2 reasons: a) a too deep hypocenter (breaking point) which makes that the earthquake is felt in a wide radius but b) the distance from populated areas

Tectonic Plates Moving Faster: Study September 12, 2014
This aerial view of the San Andreas Fault shows how an untold number of slips have altered the landscape.
Scientists say they have found that Earth’s tectonic plates are now moving faster than at any other point in the last 2 billion years.Plate tectonics is the prevailing geologic process that shapes the planet.
It triggers most of the world’s strongest earthquakes and many volcanic eruptions, along with building mountains and moving continents.
While earlier research seemed to reveal that the massive tectonic plates are actually slowing down as Earth’s core cools, New Mexico Institute of Mining and Technology geochemist Kent Condie and colleagues say they have evidence of faster plate movements.
Writing in the journal Precambrian Research, the team says they looked at how often new mountain belts form when plates collide, and compared it to magnetic data from volcanic rocks.
That allowed them to determine where the rocks formed and how quickly the continents had moved.
