INSTRUCTIONS TO AUTHORS

• Scope and policy
• Form and preparation of manuscripts
• Sending of manuscripts

ESRJ publishes the results from technical and scientific research on various disciplines of Earth Sciences and its interactions with several engineering applications.
Works will only be considered if not previously published anywhere else. Manuscripts must contain information derived from scientific research projects or technical developments. The ideas expressed by publishing in ESRJ are the sole responsibility of the authors.

We gladly consider manuscripts on the following subject areas:

• Geophysics: Seismology, Seismic Prospecting, Gravimetric, Magnetic and Electrical methods.
• Geology: Volcanology, Tectonics, Neotectonics, Geomorphology, Geochemistry, Geothermal Energy, Glaciology, Ore Geology, Environmental Geology, Geological Hazards.
• Geodesy: Geodynamics, GPS measurements applied to geological and geophysical problems.
• Basic Sciences and Computer Science applied to Geology and Geophysics.
• Meteorology and Atmospheric Sciences.
• Oceanography.
• Planetary Sciences.
• Engineering: Earthquake Engineering and Seismology Engineering, Geological Engineering, Geotechnics.

Guidelines for preparation of your manuscript

• Manuscripts must be written entirely in English, and must be spell-checked using a word processor. Please make sure that structure and grammar are appropriate. Keep in mind that ESRJ is a wide-scope journal and your article may be read by scientists from other disciplines.
• Prepare your manuscript using letter-size pages (216 mm × 279 mm). Please use size 12 Times New Roman or Arial fonts, with a double line spacing.

Figures,Tables, and Equations

• Limit figures to no more than five (5) shades of grayscale. If you use elements such as lines, line stripes, dots, or specific symbols, make sure they will be easily distinguished when reduced for publication.
• Please use CorelDraw or Canvas formats for creating your figures, if it is not possible use Tiff, Gif o Jpg.
• Please always include geographic coordinates and/or scale in maps.
• The sizes of letters are very important. Try to use the same size text throughout a figure. Figures will be reduced in size for publication. Use Times Roman or Arial fonts. Avoid using light text on dark background.
• Try to create figures that are as close as possible to the size they will appear in the printed version of ESRJ.
• Try no to use too much black in your figures. For example, some journals have found that record sections with too much black reproduce poorly.
• We require the use of S.I. physical units (m, kg, s).
• Every figure must have a number and a figure caption. The latter describes, as completely as possible, the content of the graphic. Please make sure that all symbols and abbreviations are fully explained.
• Please be aware that because we are a self-financed journal, at present, high costs do not allow us to publish color figures. All figures will be published in black and white or gray scale. Please prepare your figures accordingly.
• All tables should be numbered, have a title and must be in Ms. Excel format.
• Please send us the tables, figures and their corresponding legends in separate files.
• Please number all equations at the right.

References should be arranged alphabetically by author and should follow the format that appears in the examples below.

Manuscript Submission

Manuscripts submitted to ESRJ will only be considered if they have not been or not will be reproduced in the same extension and form in a different journal. Contributions falling into the following categories will be considered for publication:

• Regular Papers: Regular papers constitute most of the works published in ESRJ and contain original information (e.g. that has not been published, and is not being considered for publication elsewhere). There are no limitations to the lenght of regular papers, but we encourage authors to express their views in a concise manner. From our experience we have found that the shorter the paper, the better they are received.
• Brief Contributions: To be considered as a Brief Contribution, your manuscript must contain original information that may be more limited in lenght and scope than a Regular Paper. Sometimes authors wish to concisely share their research and may do so through a Brief Contribution, which should be limited to six (6) pages or less, including any figures.
• Comments, Praise, and Replies: Sometimes differences in opinions and views arise from published reasearch and the Earth Sciences community may benefit from open discussion. Sometimes an author´s outstanding contribution may be publicly praised, as a way to aknowledge the good work. Comments on and Praises to contributions as well as their Replies, should not exceed two (2) pages in lenght.
• Translations of Articles: There are many papers (specially classic papers) that represent momentous facts in the Earth Sciences history. Some other important articles remain unknown to the Spanish-Speaking or English-Speaking science communities because these articles are published in foreign languages. Translations of articles may be submitted to ESRJ provided that written authorization of original publishers is obtained.
