An earth tremor measuring 4.6 on the Richter scale occurred early on Monday in Krugersdorp on the West Rand of Gauteng.

This edition of the South Asia Disaster Report concentrates on Build Back Better (BBB), highlighting new and alternative disaster management measures to improve resilience of vulnerable communities.

An earthquake with a preliminary magnitude of 6.9 struck near Komandorskiye Ostrava in Russia's far east on Wednesday, the U.S. Geological Survey said.

The influx of millions of Syrian refugees into Turkey has rapidly changed the population distribution along the Dead Sea Rift and East Anatolian fault zones. In contrast to other countries in the Middle East where refugees are accommodated in camp environments, the majority of displaced individuals in Turkey are integrated into local cities, towns, and villages – placing stress on urban settings and increasing potential exposure to strong earthquake shaking. Yet, displaced populations are often unaccounted for in the census based population models used in earthquake casualty estimations.

In this communication, we report observation of anomalous radon gas emission measured in a borehole at India’s first multi-parametric geophysical observatory (MPGO) located at Ghuttu, Garhwal Himalaya, established by the Wadia Institute of Himalayan Geology (WIHG), Dehradun.

In this study we present a comprehensive methodology to produce a synthetic tsunami waveform catalogue in the North East Atlantic, east of the Azores islands. The method uses a synthetic earthquake catalogue compatible with plate kinematic constraints of the area. We use it to assess the tsunami hazard from the transcurrent boundary located between Iberia and the Azores, which western part is known as Gloria Fault.

A magnitude-6.5 earthquake struck the island of New Britain in northeastern Papua New Guinea at 8:47 am Monday, but no tsunami alerts or casualties are reported.

Canterbury has been hit by two strong quakes within hours. The 5.2 earthquake caused strong shaking near Cheviot just after 8am.

Accurate exposure estimation is essential for seismic risk assessment. Recent rapid urbanization and economic growth in China have led to massive spatiotemporal changes in both the asset value and GDP exposed to seismic hazards. Using available GDP data, the asset value dataset produced by Wu et al (2014a) and spatial disaggregation technology, gridded maps of GDP and asset value are overlaid with the latest seismic map to investigate spatiotemporal changes in economic exposure in the most seismically hazardous areas (MSHAs) in China in 1990, 2000 and 2010.

Our world is prone to more frequent, deadly and costly earthquake disasters, which are increasingly uncertain and complex due to the rapid environmental and socio-economic changes occurring at multiple scales. There is an urgent need to recover rapidly and effectively for community after earthquake disasters. To enhance community recovery, it is necessary to have a good initial understanding of what it is, its determinants and how it can be measured, maintained and improved.
