Thus, dense surveys between the existing profiles of MT stations are required for more detailed interpretations.
Seismologists predict that the dense surveys will yield precision imaging of magma chambers underneath volcanos and earthquake rupture zones along faults.
Taking advantage of cheap, long-lasting sensors developed by the oil and gas industry, seismologists are increasingly exploring the top 10 kilometers of the crust with dense surveys of hundreds or even thousands of seismometers.
Depth resolution of their surveys is unable to detect deeper fracture systems, but the precision of these lateral surveys to locate sharp boundaries indicates that dense surveys such as line H-1 with 5-m electrode spacing, and longer AB spreads, would be useful in further exploration.
The Toyama City has carried out seismic surveys and dense gravity surveys crossing this fault (Toyama City 2013).
This dense, elegant survey includes examples of original broadsides and limited-edition silkscreen prints that showcase Mr. Zapf's gifts as a calligrapher, as well as type specimens, dust jackets, title pages and copies of his influential manuals (Smith).

We also performed a dense gravity survey on the benchmarks to obtain information on subsurface structures.
A dense seismic survey in the SSE area of the southern Ryukyu would show the fluid distribution in the SSE fault area, which would reveal the relation between the fluid and the generation of SSEs in the Ryukyu subduction zone.
Blue line a - b indicates the dense gravity survey profile, which has gravity observation points at about 50 m intervals Fig. 8 Bouguer anomalies on the profiles (after Toyama City 2013).
