Thermospheric inter-annual variability

Using a 46-year-long dataset of the thermospheric density during 1967–2012, Liu (2016) examined the inter-annual variability in the thermosphere at 400 km and its potential connection to El-Nino Southern Oscillation (ENSO) and stratospheric Quasi-Biennial Oscillation (QBO). Wavelet analysis reveals two major modes of the thermosphere inter-annual oscillation, with the slower mode having an average period of ~64 months and the faster mode of ~28 months. Read more

Tsunami resilience of Haydarpaşa Port of the megacity Istanbul

The Marmara region located at the western extension of the North Anatolian Fault Zone (NAFZ) is one of the most tectonically active zones in Turkey. Numerous catastrophic events such as earthquakes or earthquake/landslide-induced tsunamis have occurred in the Marmara Sea basin. According to studies on the past tsunami records, the Marmara coasts have been hit by 35 different tsunami events in the last 2000 years. The recent occurrences of catastrophic… Read more

Source rupture processes of 2016 Kumamoto earthquake

The 2016 Kumamoto earthquake sequence started with an MJMA 6.5 foreshock occurring along the northern part of the Hinagu fault, central Kyushu, Japan, and the MJMA 7.3 mainshock occurred just 28 h after the foreshock. Asano and Iwata (2016) analyzed the source rupture processes of the foreshock and mainshock by using the kinematic waveform inversion technique on strong motion data. The spatial relationship between the rupture areas of the foreshock and mainshock implies a complex fault structure in this region. Click to view the article Read more

Featured article on 2016 Kumamoto earthquake

The complex rupture process of the 2016 Kumamoto earthquake sequence is an important phenomenon to understand the nature of earthquake occurrence in complex faulting zones. Yagi et al. (2016) found that the rupture process of the mainshock and the distribution of aftershocks were influenced by the high temperature area around the magma chamber of Mt. Aso. Their results have a great impact for many seismologists who are interested in the seismicity and the seismic source process of the 2016 Kumamoto earthquake. Click to view the article Read more

Determination of the 3-D distribution of electrical conductivity in Earth's mantle from Swarm satellite data: Frequency domain approach based on inversion of induced coefficients Most previous global induction studies have assumed simple structures of the source field and simplified models of the Earth, using mostly ground-based observations as data. This study presented a new approach to global induction studies using the data from Swarm geomagnetic satellite missions in order to… Read more
