This study explores temporal variations in seismic data, interplanetary parameters, and
geomagnetic indices during the 2015 Coquimbo earthquake. We employ wavelet transform …

In this paper, we estimate the seismogenic energy during the Nepal Earthquake (25 April
2015) and studied the ground motion time-frequency characteristics in Kathmandu valley …

The polar cap potential (PCV) has long been considered as a key parameter for describing
the state of the magnetosphere/ionosphere system. The relationship between the solar wind …

Geomagnetic storms are recognized as a worldwide decrease of the horizontal component
of the Earth's magnetic field measured at middle-and low-latitude magnetometers. The …

We analyzed the behavior of Cosmic-Ray (CR) intensity during five geomagnetic events
over 9-day periods of varying disturbance, using ground-based CR measurements from the …

Coronal mass ejections are the primary cause of the highly disturbed conditions observed in
the magnetosphere. Momentum and energy from the solar wind are transferred to the Earth's …

This article proposes some traditional and newly developed methods to evaluate the
properties of the magnetic cloud (MC) observed on 19–22 March 2001. We used physical …

This study reports the magnetic disturbances due to the Chilean tsunami (2015). Using 10
ground-based magnetometer observatories spread in the Pacific Ocean, covering …

This paper proposes a new method to evaluate geomagnetic activity based on wavelet
analysis during the solar minimum activity (2007). In order to accomplish this task, a newly …

The interaction between a fast-speed and a low-speed stream causes large-amplitude
Alfvénic fluctuations; consequently, the intermittency and the brief intervals of southward …
