Yogyakarta, 17-18 December 2013

Validation of “Joko Tingkir” in

the Real Time Tsunami Warning

System:

A Preliminary Result

Masturyono, Thomas Hardy, Madlazim,

and Karyono

BACKGROUND

•

The InaTEWS has been in operation since

2008



Warning : Potential Tsunami

Earthquake Information : No Potential

Tsunami

•

Criteria : Magnitude > 7.0 ; Depth < 100 km;

Located : in the sea

•

Magnitude is not good indicator for

Tsunami-genic Earthquake.

•

Madlazim developed an aplication to evaluate

the earthquake generating Tsunami by

OUTPUT SEISCOMP-3

SEISCOMP-3 is an automatic system to determine the parameters of

an earthquake and the tsunami warning.

Input : waveform data stream from the stations

Output :

1. Earthquake parameter (Origin time, Lat, Lon, Depth and the

Magnitude)

2. Map showing the location of the earthquake

WARNING OR INFORMATION

IF : NOT POTENTIAL GENERATING TSUNAMI then EARTHQUAKE

INFORMATION will be disseminated (Mag, OT, Lat, Lon, Depth, distance

from a reference point)

IF : POTENTIAL GENERATING TSUNAMI then

“JOKO TINGKIR”

Madlazim :

A software to calculate parameters as indicator of earthquake generating

tsunami.

The Parameters are : Tdur (Rupture duration), Td (Time Dominant),

T50EX, and the Products (Tdur*Td, T50EX*Td)

Tdur is associate/equivalent with the length of the rupture zone

Td is associated/equivalent with the width of the rupture zone

T50EX is associate/equivalent with the length of the rupture zone (better

estimate than Tdur)

The products are associate with the area of the rupture zone

T50EX (T50 Exceeding) is the ratio between the

Rms of the amplitude rupture duration for 50-60

seconds and the Rms of those for 0-25 seconds

CALCULATION OF THE PARAMETERS

•

T(dur), T(dom) and T50EX are calculated

for the first minute of P wave recorded in

the station.

SUMMARY

•

“JOKO TINGKIR” has been implemented in the real

time data flow within the InaTEWS Network for

validation purpose

•

Preliminary result for showing that 96.5 % of 171

event tested are consistent with the criteria set for

the validation test.

•

The criteria used in this validation test are Td*T50Ex

> 10 and Td*Tdur > 650 for earthquake generating

tsunami.

•

The total time used to get the result is about 4
