MY

DIGITAL SEISMOGRAPH STATION

AND HAWAII'S KILAUEA

VOLCANO LAVA IMAGES

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.
