Estimating the Net Effects of Migration and Remittances on Poverty and Inequality: Comparison of Fiji and Tonga [PDF]

We use original 2005 household survey data from Fiji and Tonga to estimate the impact of migration and remittances on income distribution and measures of poverty, after controlling for selectivity in migration and endogeneity in the relationship between ...

Laboratory simulations of fluid/gas induced micro-earthquakes:application to volcano seismology [PDF]

, 2014
Understanding different seismic signals recorded in active volcanic regions allows geoscientists to derive insight into the processes that generate them.

Upper-atmosphere responses to the 2022 Hunga Tonga–Hunga Ha′apai volcanic eruption via acoustic gravity waves and air–sea interaction [PDF]

Atmospheric Chemistry and Physics
A multi-group of strong atmospheric waves (wave packet nos. 1–5) over China associated with the 2022 Hunga Tonga–Hunga Ha′apai (HTHH) volcano eruptions were observed in the mesopause region using a ground-based airglow imager network.

How pro-poor is the selection of seasonal migrant workers from Tonga under New Zealand's recognized seasonal employer program ? [PDF]

Temporary migration programs for unskilled workers are increasingly being proposed as a way to both relieve labor shortages in developed countries and aid development in sending countries without entailing many of the costs associated with permanent ...

The critical role of volcano monitoring in risk reduction [PDF]

, 2008
International audienceData from volcano-monitoring studies constitute the only scientifically valid basis for short-term forecasts of a future eruption, or of possible changes during an ongoing eruption. Thus, in any effective hazards-mitigation program,

Seismic characterization of pyroclastic flow activity at Soufrier Hills Volcano, Montserrat, 8 January 2007 [PDF]

, 2007
A partial dome collapse with concurrent pyroclastic flow (PF) activity occurred at Soufrière Hills Volcano (SHV), Montserrat on 8 January 2007. Pyroclastic density currents were observed to propagate from the Northwest and West sectors of the summit dome

Uplift of the ionosphere by tropospheric and thermospheric Lamb waves induced by the 2022 Tonga volcanic eruption

Geoscience Letters
On 15 January 2022, the Tonga submarine volcano eruption generated atmospheric shocks, air pressure perturbations, tsunamis, etc., inducing traveling atmospheric disturbances (TADs) and traveling ionospheric disturbances (TIDs).

Monitoring the Hunga Volcano (Kingdom of Tonga) starting from the unrests of 2014/2015 to the 2021/2022 explosion with the Sentinel 1-2 and Landsat 8-9 satellites

Frontiers in Earth Science
This study explores the dynamic evolution of the Hunga Volcano in the Kingdom of Tonga and covers two volcanic unrests, focusing on the creation and subsequent disappearance of a new island between Hunga Tonga (HT) and Hunga Ha'apai (HH) between 2013 and
