Report on
Field Trip to Uttarkashi
Date:
4th - 6th February, 2023
Target:
Installation of Raspberry Shake seismometer in three locations
of Garhwal region.

Earth Sciences, IIT Roorkee.
The Raspberry Shake (RS) stands as the most compact
seismograph of its class globally, capable of detecting
earthquakes spanning from minuscule tremors imperceptible to
humans to the formidable seismic events occurring worldwide.
There are three variants of RS seismographs:
• Raspberry Shake 1D:
Equipped with a single Vertical Velocity Seismometer, adept at
recording Up-Down Ground Motion Activity.
• Raspberry Shake 3D:
Outfitted with three Vertical & Lateral Velocity Sensors,
capable of capturing both Up-Down and Side-to-Side Activity.
• Raspberry Shake 4D:
Features a Vertical Velocity Seismometer along with three
Vertical & Lateral Accelerometer Sensors, ensuring
comprehensive coverage for earthquakes across all magnitudes.
On February 4, 2023, a team comprising Navneet Kumar
Srivastava and Rinku Mahanta embarked on a mission to install
three Raspberry Shakes at predetermined locations within
Uttarakhand's Garhwal Himalaya. These locations were chosen
based on the availability of power supply for the instruments
and mobile network coverage. Mobile network connectivity is
crucial for the instruments, enabling the retrieval of live
data through SIM cards inserted into connected dongles. Each
instrument was safely enclosed within its respective wooden
box for protection. The team successfully completed their
fieldwork and returned to Roorkee on February 6.
The
description of the places are given below:
