A look at the blind Kumamoto experiment: combining active and passive seismic observations to avoid Rayleigh-wave mode misidentification

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

We present our pathway through participation in the blind Kumamoto exercise, particularly the Step 1 of site characterization. The combination of pass......

Combined volcano-tectonic processes for the drowning of the Roman western coastal settlements at Campi Flegrei (southern Italy)

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

The active Campi Flegrei caldera in southern Italy has a remarkably long history of coexistence between volcanism and human settlements, and it is fam......

Severe L-band scintillation over low-to-mid latitudes caused by an extreme equatorial plasma bubble: joint observations from ground-based monitors and GOLD

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

The occurrence of plasma irregularities and ionospheric scintillation over the Caribbean region have been reported in previous studies, but a better u......

Regression analysis and variable selection to determine the key subduction-zone parameters that determine the maximum earthquake magnitude

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

Large variations in the maximum earthquake magnitude ( M-max) have been observed among the world's subduction zones. There is still no universal relat......

Rupture processes of the 2021 and 2022 Fukushima-oki earthquakes: adjacent events on the complex fault system in the subducting slab

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

The 2021 M-w 7.1 and 2022 M-w 7.4 Fukushima-oki earthquakes ruptured adjacent regions in the subducting slab, which gave us a good opportunity to bett......

A two-stage deflection system for the extension of the energy coverage in space plasma three-dimensional measurements

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

The in situ measurement of charged particles plays a key role in understanding space plasma physics. Velocity distribution functions of ions and elect......

Climatology of mesosphere and lower thermosphere diurnal tides over Jicamarca (12°S, 77°W): observations and simulations

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

This work shows a 3-year climatology of the horizontal components of the solar diurnal tide, obtained from wind measurements made by a multistatic spe......

Estimation of source, path, and site factors of S waves recorded at the S-net sites in the Japan Trench area using the spectral inversion technique

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

S-net is a large-scale ocean bottom (OB) network in the Japan Trench area, consisting of inline-type 150 observa-tories equipped with seismometers and......

Favorable locations for new VGOS antennas in India depending on the assessment of geodetic parameters and environmental factors

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

VLBI simulation studies are carried out to investigate the impact of any proposed station or strategy on the geodetic parameters, such as Earth Orient......

Conjugate observations of power line harmonic radiation onboard DEMETER

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

The effects of power line harmonic radiation (PLHR) on near-Earth space have been debated for many years. Since some ultrahigh voltage AC and DC power......

Estimation of weak and strong ground motions based on diffuse field concept for earthquake for steps 2 and 3 of blind prediction exercise

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

For the accurate prediction of earthquake ground motions, the investigation of three elements in its process, namely the source, path, and site effect......

How variable are Birkeland currents?

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

I address the problem of estimating the time-rate-of-change of high-latitude Birkeland currents by using a string-of-pearls formation of satellites. S......

A plasma irradiation system optimized for space weathering of solar system bodies

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

In the tenuous atmospheric bodies of our solar system, space weathering on the celestial surface is an important process for its chemical and physical......

Improving the accuracy of polar motion prediction using a hybrid least squares and long short-term memory model

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

Earth rotation parameters (ERPs) are essential for transforming between the celestial and terrestrial reference frames, and for high-precision space n......

The relation between the surface composition anomaly and distribution of the exosphere of Mercury

期刊: EARTH PLANETS AND SPACE, 2023; 75 (1)

In celestial bodies with tenuous collisionless atmospheres, such as Mercury, the spatial distribution of the exosphere is expected to reflect the surf......
