Chinese mainland forecasts quake in Taiwan for first time
The Institute of Care-life China, based in Chengdu of Sichuan province, successfully issued a warning message prior to the recent 5.7-magnitude earthquake that struck Hualien county in Taiwan.
It is the first time the institute has publicly forecast a destructive earthquake in the island.

The quake's epicenter was located at 23.8 degrees north latitude and 121.7 degrees east longitude with a depth of 20 kilometers, according to the mainland's earthquake early warning network.
Some early-warning terminals installed at schools in Fuzhou city, Fujian province, have also received the warning message.

A 200-square-km onsite earthquake early warning system has been set up across 25 Chinese provinces, covering 80 percent of China's active earthquake zones. It has successfully predicted 26 devastating earthquakes, including the 7-magnitude Lushan earthquake, the Ludian earthquake and the Jinggu earthquake.

Major projects and the general public receive earthquake warnings via mobile phones, broadcast, and microblogs, which can reliably predict the occurrence of earthquakes and enable people to take advance precautions.

According to theoretical research, casualties could be reduced by 14 percent if residents have 3 seconds of warning time. Disasters could be reduced by 63 percent if a warning was displayed 20 seconds before a quake strikes.

"We hope the relevant authorities can continue to strengthen cooperation to provide better and more accurate earthquake early warning services," said Wang Tunbo, an expert from the Institute of Care-life China.

Zeker 83 schademeldingen na beving Appingedam
Bij het Centrum Veilig Wonen (CVW) zijn na de aardbeving van dinsdag in Appingedam zeker 83 schademeldingen binnengekomen. Dat meldde het CVW woensdag.

Scheuren

Volgens een woordvoerster gaat het voornamelijk om scheuren in muren en pleisterwerk. Appingedam werd dinsdag getroffen door een aardbeving met een kracht van 2,3 op de schaal van Richter.

Veel inwoners van Appingedam hebben de beving gevoeld. Ook de medewerkers van het CVW, dat is gevestigd in dezelfde plaats, voelden de aardschok. Vooralsnog is er geen schade aan het pand, aldus het CVW. Het Centrum Veilig Wonen heeft sinds het begin van dit jaar de schadeafhandeling van de NAM overgenomen.

Swarm of earthquakes strikes Oklahoma
A swarm of earthquakes have been recorded near several area communities since Monday afternoon.
A 4.0 magnitude quake occurred at 6:29 p.m. Monday 14 miles south-southeast of Medford and 20 miles northeast of Enid, according to U.S. Geological Survey. It was less than a mile deep.
Magnitude 3.0 or greater quakes recorded on Tuesday included:
• A 3.4 magnitude temblor at 4:39 a.m. 20 miles east-northeast of Mooreland and 54 miles west-northwest of Enid. It was 5 miles deep.
• A 3.2 magnitude earthquake at 5:07 a.m. 20 miles south-southwest of Alva and 31 miles east-northeast of Woodward. It was 3.1 miles deep.
• A 3.1 magnitude temblor at 9:31 a.m. 5 miles west-southwest of Helena and 28 miles west-northwest of Enid. It was 3.1 miles deep.
• A 3.8 magnitude quake at 2:48 p.m. 15 miles west of Medford and 26 miles north-northwest of Enid. It was 6.2 miles deep.
• A 3.5 magnitude earthquake at 3:25 p.m. 12 miles west-northwest of Perry and 21 miles east of Enid. It was 1.9 miles deep.
• A 3.0 magnitude temblor at 6:46 p.m. 9 miles east-northeast of Enid. It was 3.1 miles deep

Oklahoma Geologists: Big one is coming
STILLWATER – The frequent small earthquakes occurring in parts of Oklahoma are following a pattern that may culminate in a large earthquake, according to a presentation by Chris Hartnady, Research and Technical Director at Umvoto, an earth sciences consulting firm in South Africa. Hartnady studies the relationship between earthquakes and faults and conducts earthquake hazard assessment.

Of the geologists who converged on Stillwater this week for the Geological Society of America's South-Central Section meeting, he may have traveled the furthest.

Hartnady's presentation — “Recent Triggered (Hydro)Seismicity in Oklahoma: a Cautionary Tale?”— analyzed recent earthquakes in Oklahoma and found cycles of “accelerated seismic release.”
The first cycle started in 2008 when small earthquakes increased in number and intensity over a period of several years. It ended with a 5.6 magnitude earthquake in 2011 that was centered in Prague and released large amounts of energy, he said.

Earthquake activity then dropped off for a period of time but gradually began building again. The state appears to have entered a second ASR cycle as earthquake activity once again shows steady increases.
His analysis shows it possibly leading to a larger event like the Prague earthquake.
“It could be significant,” he said.

His analysis is only a projection and he reminded the audience that projections are unpredictable.
Hartnady said he doesn’t agree with a tendency to minimize risk and reassure the public. He thinks people should be warned about potential worst-case scenarios so they can prepare for them.

Tsunamiwaarschuwing na aardbeving Papoea-Nieuw-Guinea

Bij Papoea-Nieuw-Guinea heeft maandag een aardbeving van 7,7 op de schaal van Richter plaatsgevonden. Er is een tsunamiwaarschuwing afgegeven, meldt het U.S. Geological Survey.
Het epicentrum van de beving lag in de buurt van de stad Rabaul in het noordoosten van het land. Langs de kust van Papoea-Nieuw-Guinea en de Salomonseilanden kunnen 'gevaarlijke tsunamigolven voorkomen', aldus een waarschuwingscentrum in Hawaii. Er is kans op golven tot drie meter hoog.

Volgens eerste berichten zijn er geen gewonden gevallen. Ook zou er nog geen schade gemeld zijn.
