One of the most significant challenges in interpreting magnetic data is to mitigate the influence of the magnetization direction in the shape of the anomalies, especially when reduction to the pole fails to position them over the sources. We propose a balanced high-order filter that has low sensitivity to the direction of the resultant magnetization.

Chapter 10 - Storage and file structure. In this chapter, we probe below the higher levels as we describe various methods for implementing the data models and languages presented in preceding chapters. We start with characteristics of the underlying storage media, such as disk and tape systems. We then define various data structures that allow fast access to data.

The Sivas Basin is located in the eastern part of the central Anatolia. In this study, aeromagnetic data in the basin and surrounding area are processed and anomalies are interpreted to determine the approximate locations of the causative bodies and reveal their relationship with the tectonic trends. The sedimentary basin is surrounded by strong magnetic anomalies from the south, east, and northeast. The most apparent anomalies are observed in the E-NE of Zara, SW of Divriği, and north of Kangal.

In addition to the physical parameters such as magnetization intensity distribution, the volume and the shape of the magnetized material, directions of the magnetization and the ambient field, the distance between the observation surface and the causative sources significantly affects the shape and the amplitudes of the magnetic anomalies. Aeromagnetic surveys are performed using either a draped surface or a constant elevation plane above sea level. These surveys can easily reconnoiter large territories in a short time.

The investigation of magnetic field strength variations over subterranean layers may reveal their locations on Earth’s surface and provide physical and geometrical characteristics. Magnetic studies were carried out around Gölcük caldera lake using proton magnetometers to identify subsurface volcanic structures. The acquired data were inverted using four different edge detection algorithms such as analytic signal, tilt angle, theta map, horizontal gradient. Afterwards, the results were used to determine the locations of the anomalous structures.

The study presents thermal structure and active-passive tectonic parts of the Eastern Mediterranean Region. Curie point depth, heat flow map, Moho depth and sediment thickness are used for interpretation. The levelled magnetic data that obtained from the World Digital Magnetic Anomaly Map (WDMAM) is used. The magnetic anomaly is divided into 39 zones for Curie point depth estimation. The Curie point depth values are calculated into Fourier domain. Then heat flow map is generated. The estimated Curie point depth values are ranging from 4.5 km to 25 km.

A major earthquake (Mw=7.0) occurred in the Samos Island on the 30th of October 2020 at 11:51 UTC. Swarm satellite magnetic data were analysed for 153 days before and 46 days after the earthquake. Preearthquake and postearthquake anomaly search is constrained within the Dobrovolsky’s Circular Area. Fundamentally, there are 5 steps for processing satellite magnetic data to interpret the earthquake preparation phase. The first step is converting geographical coordinates to geomagnetic latitude and longitude.
