Aloha! My name is Tony and I live on the Big Island of Hawaii's
Kona coast. I am an amateur seismologist and I run my own digital
seismograph station and record earthquakes for the Public Seismic
Network (PSN) Redwood City
Public Seismic Network hosted by Mr. Larry Cochrane who made
this station possible. I am the only Hawaii PSN station. I
operate 2 seismometers. (KO1) is a Lehman horizontal pendulum
long period (LP) seismometer which I built. (KO2) is a vertical
short period commercial geophone from GeoSpace Corp. which is about
the size of a film can and is buried in the ground. (KO3) is a
lo-pass filtered version of (KO1) running at a higher gain. A
dedicated PC operating in DOS, with Larry's 16 bit A/D card, runs
the system with a program called SDR (Seismic Data Recorder). The
recorded earthquakes, called Type 4 event files, are then loaded
into a Windows program called WinQuake for processing. Below are
some of the seismograms from this system and will be updated on a
regular basis (see my LATEST seismograms at the PSN website) along
with some of my favorite molten lava images, taken by a friend and
I over the years, along with other images and things I may add to
my homepage later on. I hope you enjoy the seismograms and images
and thanks for visiting.
