Synthetic aperature radar patterns of seismic deformations associated with a model earthquake on the San Francisco section of the San Andreas Fault.

Earthquakes are a major concern in increasingly populated regions, however their prediction is a difficult task. Researchers have recently made progress in the use of complex simulation and modeling techniques to better forecast the occurrences of earthquakes.

In a recent study, researchers used Gradient Boosted Regression Trees, a machine learning technique for regression and classification problems that incorporates training data, to better determine spatiotemporally complex loading histories within subduction zones. The researchers simulated tens of earthquakes using a small‐scale experimental replica of a subduction zone and show that machine... read more

Himawari-8 in orbit

A group of scientists from the Riken Advanced Institute for Computational Science has undertaken a new project that aims to improve weather forecasting. The project makes use of data from the Japanese Himawari-8 satellite and combines it with a supercomputer programme at the Riken science institute. The project aims to significantly improve weather predictions, particularly in the case of extreme weather, in order to improve official warnings and to ultimately help save lives.

In order to predict future weather, weather prediction models run simulations that are based on current conditions coming from various data sources. Accurate predictions are rather difficult to conduct due... read more

Japan's 2011 earthquake. Image: NASA

A 6.9 magnitude earthquake struck off the Japanese east coast triggering a tsunami warning. The epicenter was located 67km off the coast of Fukushima prefecture with a depth of approximately 10km. The Japan Meteorological Agency issued tsunami warnings for much of the country’s northern pacific coast.

The tsunami warning was issued because three meters high waves could be expected and the nation’s public broadcaster NHK,  recommended coast residents to evacuate to higher lands because repeated waves were estimated to hit.

The Fukushima prefecture hosts the Daiichi nuclear power plant, which caused the worst nuclear disaster after a powerful earthquake on 9 March 2011 originating a tsunami that left some 18,000 fatalities, reported Aljazeera.

UNISDR head Wahlström urges world leaders to take action on disaster risk reduction

Ahead of the Third United Nations World Conference on Disaster Risk Reduction, which will take place 14 to 18 March in Sendai, Japan, the Head of the UN Office for Disaster Risk Reduction (UNISDR) Margareta Wahlström appealed to Member States to tackle the underlying drivers of disaster risks. The biggest of those drivers is climate change, accounting for 87 per cent of disasters, with other factors being poverty, land use and biodiversity degradation.

“Despite many successes and greatly improved performance in disaster management, it is sobering to note that 700,000 people have died in disaster events over the last ten years,” said Wahlström in a press... read more

More than 50 percent of the most exposed cities in the world for natural disasters are located in Philippines, China, Japan and Bangladesh, according to a recent publication by the global risk analytics company Verisk Maplecroft.

The 5th annual Natural Hazards Risk Atlas (NHRA) shows that of the 100 cities with the greatest exposure to natural hazards, 21 are located in the Philippines, 16 in China, 11 in Japan and 8 in Bangladesh. The combined risk of tropical storms and cyclones, floods, earthquakes, tsunamis and severe storms or extra-tropical cyclones, among others, has placed the small capital city of Port Vila, on the isolated South Pacific island nation of Vanuatu, on top as the world's riskiest ones.

The Philippines is the most exposed country with eight cities among the ten most risky at global level due to a high risk of tropical storms, earthquakes and landslides. In addition... read more
