Machine-learning detection of slow slip events in western Shikoku, Japan, through joint analysis of seismic and geodetic data
Abstract Over the past decade, short-term slow slip events (S-SSEs) have been detected along the entire Nankai Trough using Global Navigation Satellite System (GNSS) data. To enhance the detection of S-SSEs, we focused on the spatial and temporal coincidence of tremors and S-SSEs, a phenomenon…

Magma feeding system of the 1893 CE Meiji eruption of Azumayama Volcano, NE Japan
Abstract Azumayama Volcano is one of the most active stratovolcanoes in northeastern Japan, with a ca. 1.2 million-year eruption history. Its hazard status was raised to volcanic alert level 2 (restricted access to the crater) in 2018 and 2019 due to an increase in volcanic activity, including the…

Characterizing the magnetic signal generated in the magnetosphere from 1996 to 2024 using ground geomagnetic data
Abstract The geomagnetic field, as observed at the Earth’s surface or LEO satellite altitudes (between 300 km and 800 km), is the combination of signals generated by various internal and external sources. The internal sources are mainly associated with the liquid outer core flow, magnetized rocks…

How do core surface flow models vary when inverted from IGRF-14 candidate field models?
Abstract The International Geomagnetic Reference Field (IGRF) model is a series of models that describe the large scale magnetic field measured at the Earth’s surface. It is used by a wide range of scientists and industries, including in navigation, space weather applications, and resource…

Re-evaluation of the interseismic slip deficit rates along the Kamchatka subduction zone
Abstract An Mw 8.8 megathrust earthquake occurred off the coast of the Kamchatka Peninsula on July 29, 2025 (UTC). This event was located in the same southern segment of the Kamchatka Trench as the 1952 Mw 9.0 Kamchatka earthquake, marking the occurrence of two major earthquakes in this segment…

Cold proton nonresonant response to EMIC waves: MMS observations and a hybrid simulation
Abstract Cold protons play an important role in the Earth’s magnetosphere by modifying the dispersion relation of plasma waves. Their energy flux can be enhanced through a nonresonant response to electromagnetic ion cyclotron (EMIC) waves. This study combines Magnetospheric Multiscale (MMS)…

Partially molten plumes and magma fingers: two modes of melt transport through the mantle in terrestrial bodies
Abstract The dynamics of partially molten mantle are central to the thermochemical evolution of terrestrial bodies, and partially molten plumes driven by melt buoyancy have been recognized as a crucial ingredient. Recent numerical models of the lunar mantle, however, have revealed a distinct…

A new characteristic function to enhance earthquake detection abilities on Distributed Acoustic Sensing data, DAS
Abstract The deployment of Distributed Acoustic Sensing (DAS) for seismic monitoring has significantly increased in recent years due to its numerous advantages over conventional seismic sensors. DAS has the potential to play a crucial complementary role along with classical seismic networks…

Transient deformation from the 2016 Meinong earthquake in Southwestern Taiwan revealed by Kalman filter analysis of GNSS time series
Abstract Weighted least-squares is commonly used in GNSS (Global Navigation Satellite System) time series analysis due to its simplicity and efficiency. However, practical applications often encounter fitting issues due to unknown transient and time-varying signals in the data. To address this, the…

Ion optics of a single pair of $$\pm 45^{\circ}$$ ± 45 ∘ angular scanning deflectors for space plasma instruments
Abstract We have conducted a parameter study on the performance of the ion optics for a $$\pm$$ ± 45° deflection system used in space plasma measurements. The deflection system consists of a pair of electrodes mounted on an electrostatic analyzer. Our numerical model of the ion optics demonstrates…

The CHAOS-8 geomagnetic field model
Abstract We present CHAOS-8, an extension of the CHAOS field model series that describes the time-dependent near-Earth geomagnetic field, valid from 1999 to 2025. It is estimated from magnetic measurements collected by multiple low-earth-orbit satellites, such as CHAMP and Swarm, and ground…

IGRF-14 secular variation prediction from core surface flow acceleration
Abstract The International Geomagnetic Reference Field (IGRF) has been regularly updated since its inception in 1965. Every recent iteration contains an estimate of the geomagnetic secular variation (SV), for the intermediate years between iterations. We submit a candidate model for the geomagnetic…

Growth and thermal evolution of icy planetesimals
Abstract Icy planetesimals are thought to contribute to the volatile inventory of terrestrial planets and serve as building blocks of icy bodies in the outer Solar System. Samples from the C-type asteroid Ryugu, collected by the Hayabusa-2 spacecraft, indicate a low-temperature history with aqueous…

Predictable and unpredictable aspects of earthquakes from P-wave onsets of acceleration seismograms
Abstract It is widely acknowledged that predicting the final size of an earthquake from the P-wave onset in seismograms is nearly impossible. We confirm this fact by measuring the slope (parameter $$B$$ B ) of the acceleration record shortly after onset assuming a constant rupture speed. Since…

A DGRF 2020 candidate model only based on Swarm ASM experimental vector mode data improved through a dedicated post-calibration strategy
Abstract The ESA Swarm satellites carry a magnetometry payload consisting of an absolute scalar magnetometer (ASM), a fluxgate vector magnetometer (VFM), and a set of star trackers (STR). The primary role of the ASM is to provide 1 Hz absolute field intensity measurements, while the VFM and STR…
