A system for collecting and managing seismic data via an external communications network comprises one or more seismic stations, each including a seismic measurement apparatus producing seismic signals, a station processor converting the signals to seismic data, a station memory securely storing the seismic data on site and a station communication interface transmitting the seismic data onto an external network. The system further comprises one or more data servers, each including a server computing device, a server communication interface receiving the seismic data from the seismic stations and a server memory storing the received seismic data. The data server can determine if the received seismic data satisfies predetermined conditions for certification and/or triggering a payout in accordance with a contract, and can thereafter transmit the appropriate data signals to another location on the external communications network.

The present invention relates to a method for synchronizing continuous seismic survey. In particular, the present invention employs a semaphore scheme for the vibes to autonomously and continuously initiate sweeps, thereby decoupling the vibratory source subsystem from the recording subsystem. By using a continuous recorder and the method of the present invention, the recording trucks and the observers can be eliminated, and the vibratory sources can be initiated more efficiently than conventional systems.

The present invention disclosure is directed to a method, seismic sensor and system for wireless seismic networking. The system may comprise a low-power wide-area network (LPWAN) including wireless seismic sensors, the LPWAN being established for wireless transmission of data from the wireless seismic sensors.

A multimode seismic survey system is disclosed where seismic information for a given seismic survey is read out by different seismic units using different modes. Such multimode systems encompass hybrid arrays where information is read out via different output modes for a single seismic event, and other multimode arrays where seismic information is read out via different modes for different seismic events. The modes utilized in such arrays may include wireless, nodal and/or cable modes. The multimode arrays can be implemented using multimode seismic units or single mode seismic units. In any event, the multimode arrays can be utilized to achieve a combination of advantages associated with the different readout modes or to address any of various multimode mode contexts in relation to seismic surveys.

A system for collecting and managing parametric data via an external communications network comprises one or more parametric stations operatively connected via the external network to a certification server and a payout server.

The certification server is configured to generate a certification report based on the parametric data and a data model related to the remote source and transmit the generated certification report to the payout server. The payout server is configured to determine that terms of an associated contract are satisfied based on the certification report, and trigger a payout based on the terms that are satisfied based on the certification report.

A method of predicting parameters of an earthquake uses an array of ionosondes to scan an observed volume of an ionosphere located above a seismically active zone. The method includes monitoring ionograms provided by the array of ionosondes; detecting the presence of at least one seismic-induced irregularity (SII); determining a first predicted parameter corresponding to an epicenter location; and determining one or more predicted parameters selected from a group consisting of a magnitude, a time of occurrence, and a hypocenter depth. Algorithms for calculating the predicted parameters are presented in detail.

A wireless sensor network architecture based on multifunctional and compound sensors comprises several sensing modules including a plurality of first sensor nodes and a second sensor node. The first sensor nodes are used for collecting a target signal after sensing that a moving target enters a detection area, extracting feature information of the moving target, analyzing the feature information of the moving target to form primary target information, and transmitting the primary target information to the second sensor node, The second sensor node performs moving target matching and association on the primary target information of the moving target that is transmitted by the plurality of first sensor nodes, collects the associated primary target information to form secondary target information. A control module used for synthesizing and calibrating the secondary target information, and obtaining by merging the calibrated secondary target information, the situation evaluation of the moving target to form advanced target information.

A geophysical sensor deployment sleeve includes an electrically non-conductive fiber woven into a shape of a tube open at one end and closed at the other end. The fiber has a tensile strength such that upward force applied to the open end of the tube is capable of removal of a sensor or sensor recording node disposed in the tube in a hole below a ground surface irrespective of consolidated materials infiltrating and/or covering the tube below ground level.

A nodal seismic unit for acquiring seismic information includes an enclosure, a GPS receiver disposed in the enclosure; a motion sensor disposed in the enclosure; a LPWAN radio transceiver disposed in the enclosure; and a control unit disposed in the enclosure. The control unit is configured to transmit an unplanned movement signal to a remote operator using the LPWAN radio transceiver if the control unit receives a signal from the motion sensor indicative of an acceleration greater than a preset level.
