BEFORE YOU BEGIN

Ethical responsibilities of authors

This journal is committed to upholding the integrity of the scientific record. As a member of the Committee on Publication Ethics (COPE) the journal will follow the COPE guidelines on how to deal with potential acts of misconduct.
Authors should refrain from misrepresenting research results which could damage the trust in the journal and ultimately the entire scientific endeavour. Maintaining integrity of the research and its presentation can be achieved by following the rules of good scientific practice, which includes:
The manuscript has not been submitted to more than one journal for simultaneous consideration.
The manuscript has not been published previously (partly or in full), unless the new work concerns an expansion of previous work (please provide transparency on the re-use of material to avoid the hint of text-recycling ("self-plagiarism").
A single study is not split up into several parts to increase the quantity of submissions and submitted to various journals or to one journal over time (e.g. "salami-publishing").
No data have been fabricated or manipulated (including images) to support your conclusions.
No data, text, or theories by others are presented as if they were the authors own ("plagiarism"). Proper acknowledgements to other works must be given (this includes material that is closely copied (near verbatim), summarized and/or paraphrased), quotation marks are used for verbatim copying of material, and permissions are secured for material that is copyrighted.
Important note: the journal may use software to screen for plagiarism.
Consent to submit has been received from all co-authors and responsible authorities at the institute/organization where the work has been carried out before the work is submitted.
Authors whose names appear on the submission have contributed sufficiently to the scientific work and therefore share collective responsibility and accountability for the results.
Submissions to KeAi journals are automatically screened using iThenticate's CrossCheck within the editorial system to detect plagiarism issues including instances of overlapping and similar text in submitted manuscripts. Details can be found here. High similarity papers will be desk rejected.

In addition:

Changes of authorship or in the order of authors are not accepted after acceptance of a manuscript.
Requests to add or delete authors at revision stage or after publication is a serious matter, and may be considered only after receipt of written approval from all authors and detailed explanation about the role/deletion of the new/deleted author. The decision on accepting the change rests with the Editor-in-Chief of the journal.
Upon request authors should be prepared to send relevant documentation or data in order to verify the validity of the results. This could be in the form of raw data, samples, records, etc.
If there is a suspicion of misconduct, the journal will carry out an investigation following the COPE guidelines. If, after investigation, the allegation seems to raise valid concerns, the accused author will be contacted and given an opportunity to address the issue. If misconduct has been proven, this may result in the Editor-in-Chief's implementation of the following measures, including, but not limited to:
If the article is still under consideration, it may be rejected and returned to the author.
If the article has already been published online, depending on the nature and severity of the infraction, either an erratum will be placed with the article or in severe cases complete retraction of the article will occur. The reason must be given in the published erratum or retraction note.
The author's institution may be informed.

Tables

For each table, please supply a table caption (title) explaining the components of the table.
All tables are to be numbered by Arabic numerals.
Tables should be always cited in text in consecutive numerical order.
Identify any previously published material by giving the original source in the form of a reference at the end of the table caption.
Footnotes to tables should be indicated by superscript lower-case letters (or asterisks for significance values and other statistical data) and included beneath the table body.

Acknowledgments, Data Availability, Declaration of Competing Interests

Acknowledgments of people, grants, funds, etc. should be placed in a separate section before the reference list. The names of funding organizations should be written in full. Statements about Data Availability and Declaration of Competing interests should also be included in this section.

Declaration of interest

All authors must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential competing interests include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. Authors must disclose any interests in two places: 1. A summary declaration of interest statement in the title page file (if double anonymized) or the manuscript file (if single anonymized). If there are no interests to declare then please state this: 'Declarations of interest: none'. 2. Detailed disclosures as part of a separate Declaration of Interest form, which forms part of the journal's official records. It is important for potential interests to be declared in both places and that the information matches. More information

Preprint posting on SSRN

In support of Open Science, this journal offers its authors a free preprint posting service. Preprints provide early registration and dissemination of your research, which facilitates early citations and collaboration.

During submission to Editorial Manager, you can choose to release your manuscript publicly as a preprint on the preprint server SSRN once it enters peer-review with the journal. Your choice will have no effect on the editorial process or outcome with the journal. Please note that the corresponding author is expected to seek approval from all co-authors before agreeing to release the manuscript publicly on SSRN.

You will be notified via email when your preprint is posted online and a Digital Object Identifier (DOI) is assigned. Your preprint will remain globally available free to read whether the journal accepts or rejects your manuscript.

For more information about posting to SSRN, please consult the SSRN Terms of Use and FAQs.

First Look

Please note: posted preprints for this journal will appear in a dedicated journal-branded First Look space on SSRN.

Manuscript submission

Manuscript must contain original research that has not been published before or under consideration by other journals. The submission has been approved by all co-authors and no one who has contributed significantly to the manuscript is omitted. The publisher will not be held legally responsible should there be any claims for compensation.
Submission to this journal is through the online system only. Use the following guidelines to prepare your article. Via the homepage of this journal (https://www.keaipublishing.com/en/journals/earthquake-science) you will be guided stepwise through the creation and uploading of the various files. The system automatically converts source files to a single Adobe Acrobat PDF version of the article, which is used in the peer-review process. Please note that even though manuscript source files are converted to PDF at submission for the review process, these source files are needed for further processing after acceptance. All correspondence, including notification of the Editor's decision and requests for revision, takes place by e-mail and the online system, removing the need for a hard-copy paper trail. If you are unable to provide an electronic version, please contact the editorial office prior to submission (E-mail: equsci@cea-igp.ac.cn; equsci@126.com. Tel: +86-10-68729344).
ORCiD ID: Our journal supports the use of ORCiD ID. Authors are encouraged to provide ORCiD ID at submission.

Text format

A Word file is preferred for the submitted manuscript with a fontsize 11 pt or bigger. But, again, manuscript in any form will be accepted in the initial submission.

Manuscript preparation and submission

Authors should submit their manuscripts online through Editorial Manger at (https://www.editorialmanager.com/eqs/default1.aspx) and upload all of your manuscript files following the instructions given on the screen.
Submit a single word file (preferred) or pdf file including all text and figures tables for review. Separate files for Supplementary Information are allowed. During the review process, authors can prepare their manuscript in any forms. However, some guidance is provided below. In the final production, uniform formatting and editorial policies will be implemented. Please check journal website for examples of published manuscripts.

Permissions and reuse of published materials

Reuse of published materials (in print or online) is permissible if permission from the copyright owner(s) of the materials is obtained.

Language editing

Manuscripts that are accepted for publication will normally be checked by our copy editors for spelling and formal style. This may not be sufficient if English is not your native language and substantial editing may be required. In that case, you may want to ask a native speaker to help you or have your manuscript edited by a professional language editor prior to submission. The journal can refer third-party English language editing service if the authors desire.

PEER REVIEW

This journal uses a double blind review process. All contributions are sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor-in-Chief is responsible for the final decision regarding acceptance or rejection of articles. The EiC's decision is final. For more information on the types of peer review, please visit: https://www.elsevier.com/reviewers/peer-review.
1.All manuscripts would be first reviewed by the editorial office, which will conduct the initial technical check first. Any papers that fail to meet the basic standard of the journal would be rejected for reasons like out of scope, ethic issues, high similarities, and so on. Then, the editorial office will reassign selected papers to the EiC.
2.The EiC will assign the article to an Associate Editor, AE, who will invite multiple reviewers to review this paper.
3.After at least 2 reviewers give their review comments, the AE will provide feedbacks based on review comments and his/her own additional comments. The AE will make a recommendation to the EiC, who will inform the authors.
4.When the author submits the revised manuscript, the process will follow accordingly. The EiC will make the final decision.
5.For submissions from the EiC or AE, other journal editors handle them independently.

The remaining body of the manuscript should include the following sections:

Introduction
Methods
Results
Discussions
Conclusions

Color illustrations

Online publication of color illustrations is free of charge. For color in the print version, authors will be expected to make a contribution towards the extra costs.

Proof reading

The purpose of the proof is to check for typesetting or conversion errors and the completeness and accuracy of the text, tables and figures. Substantial changes in content, e.g., new results, corrected values, title and authorship, are not allowed without the approval of the Editor.
After online publication, further changes can only be made in the form of an Erratum, which will be hyperlinked to the article.

Online first

The article will be published online after receipt of the corrected proofs. This is the official first publication citable with the DOI. After release of the printed version, the paper can also be cited by issue and page numbers.

Terminology

Please always use internationally accepted signs and symbols for units (SI units).
Please use the standard mathematical notation for formulae, symbols etc.: Italic for single letters that denote mathematical constants, variables, and unknown quantities Roman/upright for numerals, operators, and punctuation, and commonly defined functions or abbreviations, e.g., cos, det, e or exp, lim, log, max, min, sin, tan, d (for derivative) Bold for vectors, tensors, and matrices.

Ethical standards

Manuscripts submitted for publication must contain a statement to the effect that all human and animal studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or failure to fulfill the above-mentioned requirements.
Please see our information on Ethics in publishing and Ethical guidelines for journal publication.
Submissions to KeAi journals are automatically screened using iThenticate's CrossCheck within the editorial system todetect instances of overlapping and similar text in submitted manuscripts. When a plagiarism complaint is raised, we recommend following the actions as mentioned here

In-text citation style

Cite references in the text by name and year in parentheses. For Chinese authors, initials of first names are also included. Some examples are as follows.
Negotiation research spans many disciplines (Thompson 1990).
This result was later contradicted by Becker and Seligman (1996).
This effect has been widely studied (Abbott 1991; Barakat et al. 1995).
It was first discovered by Song XD and Richards (1996).

Preprint references

Where a preprint has subsequently become available as a peer-reviewed publication, the formal publication should be used as the reference. If there are preprints that are central to your work or that cover crucial developments in the topic, but are not yet formally published, these may be referenced. Preprints should be clearly marked as such, for example by including the word preprint, or the name of the preprint server, as part of the reference. The preprint DOI should also be provided.

Journal Abbreviations

Abbreviations should be defined at first mention and used consistently thereafter.

Post-publication amendments

Errata and Corrigenda
We will publish a correction of your article if a significant error is discovered after publication. An Erratum will be published if we introduced the error; a Corrigendum if the author introduced the error.
Retractions
Articles may be withdrawn, retracted, removed or replaced after publication if they contain substantial errors that cannot be corrected by publishing an Erratum or a Corrigendum, or if ethical violations come to light after publication.
