Ultra-low frequency acoustic waves called "acoustic gravity waves" or "infrasounds" are theoretically expected to resonate between the ground and the thermosphere. This resonance is a very important phenomenon causing the coupling of the solid Earth,

Anomalous crustal uplift has continued since 1976 in the Izu Peninsula, Japan. Earthquake swarms have also occurred intermittently off the coast of Ito since 1978. Observations of the total intensity of the geomagnetic field in the peninsula started

Macro-anomalies preceding a number of large earthquakes in Japan are analyzed in relation to maximum detectable distance, D max , from the epicenter and to precursor time, T , between anomaly appearance and main shock occurrence. These anomalies incl

In order to investigate changes in the geomagnetic field associated with seismic activity in the western part of the North Anatolian Fault Zone (NAFZ), seven continuous measurement stations and eighteen repeated-survey sites were set up in the Inik-G

An earthquake swarm started in the north-eastern part of the Izu Peninsula at the end of June 1989. The swarm was the most active during the period from July 4 to 10, during which the largest earthquake of M5.5 occurred. Then a sea-bottom eruption oc

Measurements of the geomagnetic total intensity were carried out in the western part of the North Anatolian Fault Zone. In particular, profile measurements were made across some fold structures in the graben. The data show anomalies presumably relate

A general theory of piezomagnetism in a uniform medium leads to the conclusion that a 1-nT change in the geomagnetic total intensity represents a change of 1.8×10-5 in strain. Empirically, however, a much larger tectonomagnetic change ΔF in units o
