A method for distributing geophones around a seismic data source includes distributing a first geophones each including a first piezoelectric system in a first region in which the seismic data source is located then distributing second geophones each including a solar cell in a second region surrounding the first region. The second geophones further include a housing, a spike provided on a bottom surface of the housing, a sensor configured to sense seismic data; a processor configured to process the seismic data, a transceiver configured to transmit the processed seismic data and receive radio frequency (RF) signals wirelessly; and a power device. The power device is coupled to the sensor, the processor and the transceiver. The power device is configured to harvest energy from an environment where the geophone is located. The power device includes a solar cell provided on a top surface of the housing, a piezoelectric system provided on an edge of the housing adjacent to the top surface, and a thermoelectric generator provided on a bottom surface of the housing and a surface of the spike.

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 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.

A cableless seismic acquisition system that is configured to resolve the locations of a plurality of cableless seismic acquisition units (e.g., up to 1,000,000 or more) of the system at sub-meter levels of accuracy (e.g., less than 10 cm, less than 5 cm, etc.) free of many of the limitations of existing manners of determining cableless unit locations in seismic acquisition systems. While accurately determining cableless unit locations for use in mapping underground structures of interest, the disclosed cableless seismic acquisition system also limits power demands of and ultimately power consumption by the cableless units to extend serviceable deployment time of the cableless acquisition system.
