Marsquake Locations and 1-D Seismic Models for Mars From InSight Data.

We present inversions for the structure of Mars using the first Martian seismic record collected by the InSight lander. We identified and used arrival times of direct, multiples, and depth phases of body waves, for 17 marsquakes to constrain the quake locations and the one-dimensional average interior structure of Mars. We found the marsquake hypocenters to be shallower than 40 km depth, most of them being located in the Cerberus Fossae graben system, which could be a source of marsquakes.

The Interaction between Lockdown-Specific Conditions and Family-Specific Variables Explains the Presence of Child Insomnia during COVID-19: A Key Response to the Current Debate.

It is still debated whether lockdown conditions in response to the coronavirus disease 2019 (COVID-19) health crisis seriously affected children's sleep. For young children, some studies identified more insomnia, while others only transient disturbances, or even no effect. Based on the premise of mother-child synchrony, a well-known dynamic established in child development research, we hypothesized that principally, the children whose mothers perceived the lockdown as stressful and/or responded maladaptively, suffered sleep disturbances.

Seismic detection of the martian core.

Clues to a planet's geologic history are contained in its interior structure, particularly its core. We detected reflections of seismic waves from the core-mantle boundary of Mars using InSight seismic data and inverted these together with geodetic data to constrain the radius of the liquid metal core to 1830 ± 40 kilometers. The large core implies a martian mantle mineralogically similar to the terrestrial upper mantle and transition zone but differing from Earth by not having a bridgmanite-dominated lower mantle.

Repeated giant earthquakes on the Wairarapa fault, New Zealand, revealed by Lidar-based paleoseismology.

The Mw 7.8 2016 Kaikoura earthquake ruptured the Kekerengu-Needle fault resulting in the loading of its eastern continuation, the Wairarapa fault. Since the most recent earthquake on Wairarapa occurred in 1855 and is one of the strongest continental earthquakes ever observed, it is critical to assess the seismic potential of the Wairarapa fault, which might be prone to break.

A life in waiting: Refugees' mental health and narratives of social suffering after European Union border closures in March 2016.

Rationale: In 2015, an estimated 856,723 refugees, predominantly from Syria, Afghanistan, and Iraq arrived in Greece as an entry point into the European Union. The border of the Former Yugoslav Republic of Macedonia closed in March 2016, blocking a popular route for refugees through Europe, and left around 60,000 people stranded in Greece.

Objective: A mixed-method study was conducted among refugees in the regions of Attica, Epirus, and Samos between November 2016 and February 2017.

Syrian refugees in Greece: experience with violence, mental health status, and access to information during the journey and while in Greece.

Background: Since 2015, Europe has been facing an unprecedented arrival of refugees and migrants: more than one million people entered via land and sea routes. During their travels, refugees and migrants often face harsh conditions, forced detention, and violence in transit countries. However, there is a lack of epidemiological quantitative evidence on their experiences and the mental health problems they face during their displacement.
