Philippines struck by 3 earthquakes in 20 minuets

The Philippines experienced a earthquake swarm this afternoon at about 3 pm Philippines time. The earthquakes occurred on the island of Luzon near the city of Batangas. Luzon is the largest and most populated island in the Philippines. The third earthquake to hit was the strongest measuring  5.9 mm. The USGS said the quake was at a depth of 42.7 km (27 miles). After the earthquakes the residents fled the coastal city for higher ground because they feared the earthquake could produce a Tsunami. “Residents in the coastal villages in two towns have evacuated to safer ground after the earthquakes,” Lito Castro, head of the provincial disaster council, told local radio. “The people were afraid the earthquakes would generate a tsunami.” I find this fact interesting because if the earthquake occurred in a non coastal location peoples reaction to the earthquake would possibly be different. The people of the Philippines are aware of the  of earthquakes causing tsunamis so they immediately know to flee to higher ground. ” The area is still experiencing aftershocks. Fortunately, so far there are no reports of casualties.

Botswana earthquake: Tremor felt as far away as South Africa and Mozambique

A very strong earthquake struck Botswana just a while earlier. The depth was very shallow. There is still little news I could find this early, but a shallower earthquake would definitely cause more damage. Source was http://bnonews.com/news/index.php/news/id5801

An additional Source indicated the magnitude was 6.8 and the strongest ever recorded there.  http://www.express.co.uk/news/world/787427/earthquake-botswana-largest-ever-south-africa

The earthquake, which struck at 7:40 p.m. local time on Monday, was centered about 44 kilometers (27 miles) east of Gope, or about 229 kilometers (142 miles) northwest of Gaborone. It struck at a shallow depth of about 10 kilometers (6.2 miles).

The U.S. Geological Survey (USGS) put the preliminary magnitude of the earthquake at 6.5, making it the largest earthquake on record to have struck Botswana. The European-Mediterranean Seismological Centre (EMSC) puts the preliminary magnitude at 6.7.

Shaking has been felt across southern Africa, with reports of tremors being felt in the capital Gaborone and neighboring countries, including in Johannesburg and Pretoria in South Africa. Shaking has also been felt in Zimbabwe and Mozambique.

There was no immediate word on possible damage or casualties but we’e working to gather more information.

Monday’s earthquake is the largest earthquake on record to have struck Botswana, surpassing a 5.9-magnitude earthquake that struck the same region in September 1952.

4.1 Magnitude Earthquake strikes Oklahoma

Initially rated as a 4.4, U.S. Geological Survey officials have downgraded an earthquake which struck a northern, remote area of Oklahoma this past Wednesday at 10:37am. Shaking was most felt by Grant County, in between Medford and Deer Creek, about 95 miles north of Oklahoma City. Grant County Emergency Management director, Brandon Fetters, stated that the quake “struck an isolated area and there are no reports of injuries or damage.”

In recent years, thousands of earthquakes have been recorded in the state of Oklahoma. Many can be linked to the underground injection of wastewater from oil fracking operations. Due to the upswing in somewhat low magnitude earthquakes, environmental and policy regulators have directed oil and natural gas producers to close up several water disposal wells and/or reduce the injected volume of fluids.
As a result of oil and natural gas companies’ endeavors, further internet research shows these startling statistics in Oklahoma alone:

  • “15 earthquakes in the past 7 days
  • 113 earthquakes in the past 30 days
  • 1,410 earthquakes in the past 365 days”

Additionally, an earthquake tracker link has been provided at the bottom, which logs the locations, magnitudes, and times of all of Oklahoma’s earthquakes. Just on the first page of the earthquake statistics, it appears that Oklahoma has experienced at least one low-magnitude earthquake every day for the past ten days.

Russia stuck by 6.6 magnitude earthquake

Earlier today a 6.6 mm earthquake occurred off of Russia’s east coast near the Kamchatka peninsula at 11:00 am EST  (4 am UK time). The focus of the earthquake was at a depth of 22.8 km. There was the possibility of a 1.5m Tsunami but Russia’s emergencies ministry later recalled the warning.

Earthquake hits Lahad Datu

Today an earthquake hit Lahad Datu. It is reported as a magnitude of 4.2. The earthquake with an 8km depth was also felt in Kunak, Tawau, Sandakan and other surrounding areas. There are not yet any reports if anyone has been injured however it was reported by Azmi Daud from the Sabah Meterological Department that it was a weak earthquake with the implication that there is no need to worry.

Geospatial data and analysis for disaster relief

This post is an excerpt from Geospatial Data and Analysis, by Aurelia Moser, Jon Bruner, and Bill Day. If you click on the link below, it will take you to the post, but it also has a link to read more from this book and contains some really cool and useful information!

This post talks more about the recovery process of disasters and how technology has advanced to allow disaster relief agencies to use geospatial data that goes down to the level of individuals, as well as maps showing key infrastructure and up-to-date damage assessments created on the fly, in order to manage response efforts. Ten years ago, geospatial data was not rich enough to map these real-time movements of people and resources, but now that smart phones are ubiquitous around the world, this is something that is available and is being used very heavily in recent disasters.

A few examples are mentioned in the post about how drones are being used more and more and that their videos can be transformed into 3D models. Skycatch is the main industry behind this development. It originally sold this transforming software to construction companies working on very large projects, but it ended up joining the relief effort following the Nepal earthquake in 2015. “Data from the drones was used to identify damaged buildings, map paths for heavy equipment, and plan for the restoration of heritage sites.”

These are just a few of many advancements in technology we have made (and an idea of what else we can do with this technology) with regards to enhancing the relief and recovery processes following disasters and catastrophes.

Small Earthquake(s) in Mt. Gambier

 

“Humans make great seismologists — we are pretty sensitive. We feel every little bump that goes off.”

There were two earthquakes felt by the residents in Wandilo, Australia, a city located north-west of Mount Gambier. The tremors were so small, they went undetected by the seismograph. Rather, the scientists in charge of the Geoscience Australia website learned about the earthquakes from residents who reported it on the webpage. The scientists estimate that the initial tremor could be felt about 25 kilometers away from the estimated epicenter.

The second earthquake, occurring at roughly 5pm (local time) may have just been a secondary quake linked to the first one. The data from the monitors will let them know if it was a true, independent case or not.

This is the second (and possibly third) earthquake of the year for this area. The first occurrence was in early February.

Nepal Government Bulldozes a still In-Use Relief Camp from 2015 Earthquake

Although not a natural disaster in and of itself, Nepal’s decision to destroy a relief camp housing 2,000 people in bamboo and plastic huts certainly is tied to its mitigation efforts from an earthquake which devastated Nepal in 2015. The political move served as a final bid to force displaced people to return to their home villages and rebuild, as many of them still lie in ruins almost two years later.

The earthquake killed 9,000 people and claimed nearly one million homes. Over the past two years, reconstruction has moved at a snail’s pace, with Nepal’s government’s attention divided between recovery management and an ongoing political crisis. Police in riot gear stood outside of the bulldozed relief camp last Tuesday to contain the forcibly removed residents and eject them from the area, located in the nation’s capital.

This camp, among others, was meant to serve as a temporary shelter for the survivors of Nepal’s worst natural disaster in one hundred years. Government bureaucrats are encouraging poor, displaced people to take the government-provided relief money and to go rebuild on their own. The plan seems to openly ignore the country’s existing lack of infrastructure, organization, and attention to their most vulnerable populations. So far, 76,000 homes have been rebuilt, as government figures show, and 553,000 families have received $500 in aid. This contrasts with the government’s original figures two years ago, which determined that more than 600,000 families were hit by the quake, and each was entitled to $2,000 in aid.

Bimal Dulal, 52, a laborer and former resident of the bulldozed camp (Kathmandu) since the earthquake stated: “I don’t have any house of my own to rebuild and can’t find any room on rent to move from the camp.”

Japanese Government Found Liable for Fukushima

The Maebashi District Court said the nuclear incident was “preventable,” arguing the government should have been more forceful in making TEPCO take precautionary measures. The court also blasted TEPCO as too financially motivated, at the expense of human safety.

“It was extremely significant that [a court] has acknowledged the responsibility of the state,” counsel for the plaintiffs, who were awarded 38.55 million yen between 137 people, said in a statement.

The 2011 meltdown was part of the broader disaster of the Great East Japan earthquake and tsunami, which claimed more than 15,000 lives. The quake measured a massive 9.0 on the Richter scale, the largest recorded earthquake ever to hit Japan.
