Cornwall Earthquake

On 8th August 2019 a small earthquake happened in Cornwall, UK.   Despite being less than magnitude 3 it caused great excitement locally, and even nationally.
At the time this earthquake happened the deep geothermal energy company United Downs had just set up a network of low cost raspberryshake seismometers in local schools as part of their community outreach programme.

These simple, lowcost seismometers easily detected the signal from this earthquake right across the county.    Data from these sensors can be downloaded from an online archive using simple Python programs and using the ObsPy Python library

from obspy.clients.fdsn import Client
from obspy import UTCDateTime
import matplotlib.pyplot as plt
# station names
seislist=['RB30C','RB5E8','RD93E','R82BD','R7FA5']
# set the data window
starttime=UTCDateTime("2019-08-08 16:52:05.10")
# read in list of Raspberry Shakes by looping through the list from the second seismometer
client=Client(base_url='https://fdsnws.raspberryshakedata.com/')
waveform=client.get_waveforms('AM',seislist[0],'00','EHZ',starttime,starttime+15)
for x in range (1,len(seislist)):
    waveform+=client.get_waveforms('AM',seislist[x],'00','EHZ',starttime,starttime+15)
waveform.detrend(type='demean')
waveform.plot(size=(1024,800),type='normal', method='full',equal_scale=False, starttime=starttime)

Getting data from a BBC:microbit

Image
Since the BBC:microbit has an accelerometer chip on it it seems only natural to turn it into the heart of an educational seismometer. microbit accelerometer data recorded by jAmaseis datalogging software So what steps need to be done 1) install the mbed serial driver to connect your microbit to your (windows) computer using a USB lead 2) write some code to output acceleration data to the serial line on the microbit 3) make sure you have  suitable microbit device file for jamaseis 4) connect it all together In detail 1) install the mbed serial driver for windows see   https://developer.mbed.org/handbook/Windows-serial-configuration     This will create a virtual serial COM port on your computer... you can check this by looking at Computer...properties...device manager (windows7) On my computer the microbit appears as COM23  2) write some code to output acceleration data to the serial line..  you can do this in a browser on the mic...
