PrefaceDubai Municipality installed the first earthquake monitoring system

in UAE since April 2006, which consists of four broadband seismic stations

to monitor the local and regional earthquakes which may have an effect on

UAE and especially on Dubai Emirate. The earthquake information system

provides support to the government organizations, Police and Civil defense

in case of any felt earthquake in the region. Ongoing public awareness

program for earthquakes and safety instructions is one of the Municipality

contributions to the community services to reduce the earthquake hazard.

The network is running properly, online data exchange between National

Center of Metrology and Seismology of Abu Dhabi, neighboring countries

(Oman and Kuwait) and the Global Digital Seismic Network is established

which increases the detectability and aperture of the network.

On April 2012, Dubai Municipality installed 5 strong motion stations

located closer to Dubai urban areas. These new stations supports the

automatic generation of ShakeMap that describe the extent of potentially

damaging shaking following any effective earthquake. This project is a part from

DM promotion to the disaster countermeasure of Dubai City for emergency

response, loss estimation, and for public information through the media.

On June 2013, an independent backup server was installed at Umm

Suqeim Dubai Municipality sub-center to acquire and analysis the

earthquake data in case of any emergency in the main center at main

building of Dubai Municipality.

While on December 2014, Structural Health Monitoring (SHM)

System (24 strong motion channels) was installed on Rashid Tower (Dubai

World Trade Center) to support the Enhanced Rapid Post-event Assessment

solution. While on June 2015, another SHM system (24 strong motion

channels) was installed on Burj Khalifa.

On 2017, two SHM systems were installed on Dubai Municipality

main building and Dubai Police Forensic Science and Criminology Building

with 18 channels of strong motion sensors. All SHM systems were support

by a smart application (DB-Safe/ OasisPlus for Dubai) to increase the safety

3

of Dubai residences and to avoid the unnecessary evacuation during any felt

event from southern Iran,

Although, Dubai Emirate own around 20% of high rise building

around the world, Survey Department, Dubai Municipality start to monitor

the effect of earthquakes on these towers for instantaneous support to the

towers safety teams and building occupants with valuable data that showed

any significant shaking above levels of human discomfort, how the building

is influenced and how they can response in a smart way within very limited

time.

The present bulletin is one of the products of the Dubai Seismic

Network.

CONFIGURATION OF DUBAI SEISMIC NETWORK (DSN)

The seismic monitoring system consists of a central processing unit (CPU) located in the

Survey Department, Dubai Municipality, which receives seismic data from four seismic stations

via 4 hybrid communication links consisting of spread-spectrum Ethernet radios and digital lease

lines as well as an end user provided internet access for real time data exchange (Fig. 1). The

remote station consists of a 6-channel high resolution, IP-aware digitizer (Q330), a broad-band

seismometer (STS-2) and a force balance accelerometer (ES-T). Table 1 shows the name, code,

and coordinate of the stations. The digitizer converts the analog seismic signal to digital data at

100, 20 and 1 sample/second. Figure 2 shows the Dubai seismic monitoring system drawing

overview. The network is completely based on TCP/IP communication which allows reliable data

acquisition and control of the remote sites from the data center. ANTELOPE software (5.4) is

used for data acquisition and analysis.

The real-time system exchanges data via the orb-exchange-protocol to and from the

Earthquake Monitoring Center (EMC) of Oman and Kuwait National Seismic Network (KNSN)

which improves the detection and location accuracy of local and regional earthquake in the

region. Real time data exchange between Dubai Seismic Network (DSN) and NCMS is done

through seed link-orb-protocol. All of these real time data enhance the detectability of smaller

earthquakes and help to delineate the active faults in northern UAE.

Besides these local and regional stations from neighboring centers and countries, few

broadband stations from the Digital Global Seismic Network (Fig. 3) were also added to the DSN

database to increase the efficiency and detectability of the DSN network for remote and

teleseismic events in real time. The parameters of regional and global seismic stations recorded

in real time by DSN center are listed in Table 2.

On April 2012, Dubai Municipality installed 5 strong motion stations (Fig. 2) located

closer to Dubai urban areas. These stations sent their digital records to DSN via GPRS

technology. The locations of these stations (Table 1) are selected to cover most of the urban area

and to reflect the ground motion response for different soils beneath Dubai urban area. The shake

maps for the earthquakes are automatically generated according to their magnitudes (local events

ML > 3 and regional events mb> 5) on real time after the occurrence of the events by less than 5

minutes and published on Geodesy & Hydrographic Survey Section, Survey Department, Dubai

Municipality web site.

This quick, accurate and important information can aid in making the most effective use

of emergency-response resources, loss estimation and for public information through the media.

MAGNITUDE CALCULATION

Local Magnitude is estimated according to Richter magnitude by ORBMAG program.

Each waveform segment is converted to equivalent drum recorder displacement of a standard

Wood-Anderson instrument and the maximum amplitude for the event is determined. These

amplitudes are fed into the standard Richter magnitude formula for computing ml values for each

station and all of the station ml values are median averaged to get a total network ML estimate.

Body wave (Mb) and surface wave (Ms) magnitudes are estimated according to the

general formulas within ANTELOPE software:

Mb = log10 (amp) + 1.66 log10 (Δ) - 0.104

Ms = log10 (amp) + 1.66 log10 (Δ) – log10 (Δ*0.0097+9) + 0.52

Where Δ: distance between source and receiver in degrees.

DUBAI STRUCTURAL HEALTH MONITORING (SHM) SYSTEM

On December 2014, DM installed 24 strong motion channel sensor on Rashid Tower-

Dubai World Trade Center (Fig. 4) to manage the Post-event Assessment Solution. The primary

objective is to prevent unwarranted distress among Dubai citizens and unnecessary business

interruption caused by unwarranted evacuations, and to minimize periods of downtime waiting

for an official decision to reoccupy. A similar system was installed on Burj Khalifa on June 2015

(Fig. 5). While, on 2017 two SHM systems were installed on Dubai Municipality main building

and Dubai Police forensic science and criminology building with 18 channels of strong motion

sensors. All SHM systems were support by a smart application (DB-Safe/ OasisPlus for Dubai) to

increase the safety of Dubai residences and to avoid the unnecessary evacuation during any felt

event from southern Iran. Dubai Emirate own around 20% of high rise building around the world,

Survey Department, Dubai Municipality start to monitor the effect of earthquakes on these towers

for instantaneous support to the towers safety teams and building occupants with valuable data

that showed any significant shaking above levels of human discomfort, how the building is

influenced and how they can response in a smart way within very limited time (Figs. 6, 7). Also,

the smart application support the public residents away of these towers by all earthquake

information and safety tips and receive their feedbacks and comments to develop this smart

application.

HISTORICAL AND RECENT SEISMICITY OF UAE

Historically, there are no reports or indication of any destructive earthquake in UAE. This

could be a result of poor catalogue completeness with respect to M>5 earthquakes and their long

recurrence time. Recent seismic activity from 1964 up to June 2006 shows few scattered inland

earthquakes due to the availability of seismic stations in the region. The most significant inland

earthquake is that of March 11, 2002 (Mw ~5) earthquake which occurred in Masafi area and

recorded by the worldwide seismic networks (Fig. 8). This moderate size event was felt

throughout the northern emirates and was accompanied by smaller (felt) events before and after

the March 11 main shock. The majority of seismic activity took place on the southern part of Iran

along Zagros belt as a result of the collision between the Arabian Plate and Eurasian plate. This

belt presents one of the most seismically active continental regions on the Earth.

Masafi 11/03/2002 (5.1)

15

LOCAL SEISMIC ACTIVITY

The observed seismic activity from April 2006 to December 2017 indicates light local

seismicity on northeastern part of UAE along Masafi-Bani Hamid area, near Wadi Nazawa and

northern Huwaylat (Fig. 9). Most of the inland seismic activity took place to the east of Masafi

and constitute a cluster of activity nearly trending NE. This trend may be continues beneath the

Oman Sea and extends towards Iran. This trend may be an impact of the shear zone separating the

two different tectonic processes; a collision along Zagros Belt and a subduction along the Makran

Zone.

The seismic activity in Wadi Nazwa may be related to the gas production in Margham

field. The focal depth of these earthquakes are shallower (h < 5km), and their magnitude are less

than 3. Moreover, the light activity northern Huwaylat may be related to small fault segment

(~5km) trends NE similar to the eastern Masafi activity. Few of the inland earthquake activity are

felt and best recorded by the DM broadband stations. The most significant of these felt events are

that of March 10, September 13, 2007, February 12, 2008, February 20, 2011, April 14, 2011 and

October 21, 2012 earthquakes that occurred in the northeastern part of UAE (Fig. 10). The

estimated average local magnitudes of these events were 4.0, 4.4, 3.7, 3.4, 3.2 and 3.8,

respectively. No injuries were reported for all of them but the shaking was strong enough in some

of them to frighten many residents in AlFujairah, Masafi, Dibba and Khor Fakkan.

Besides these inland felt events, few offshore felt events were well recorded by the local

and regional broadband station of DSN, NCMS and EMC (Oman) centers. These records provide

an excellent opportunity to study the tectonic process and present day stress field acting on this

area. Regional full waveform inversion of all felt inland earthquakes northeastern UAE show

normal faulting mechanisms along nearly NNE-SSW fault planes, in perpendicular direction to

the major shortening direction between Arabian plate and Eurasian plate at Zagros Belt. The focal

mechanism of a closer event to Iran in the Arabian Gulf indicate reverse fault at deeper focal

depth (above 30 km). The focal mechanisms of the offshore events are consistent with the

predominant compression stress regime in Oman Sea, except for the event of June 8, 2009 off

shore to the east of Musandam which shows normal faulting mechanism. The installation of new

broad band stations, defining accurate crustal structure and sharing seismic data between Arabian

Gulf countries are highly recommended to reduce the earthquake hazard on the region.

16

The deployment of seismic networks in Dubai, Abu Dhabi and Oman reveal low to

moderate tectonic activity in the northern Oman Mountains that was previously unknown.

Continued observation and analysis will reveal the characterization of seismicity and assessment

of seismic hazard in the region.

LOCAL SEISMIC ACTIVITY OF 2017

On 2017, DM seismic stations record 933 of local, regional and teleseismic events. Of

them, 4 local earthquakes took place inland (Fig. 11). Two of these local events occurred to the

south of Masafi, one northern Oman and one along the eastern border of Sharjah. Few offshore

events took place to the east and north of Musandam. While few smaller events took place

offshore Dibba Al Fa Fujairah. The rate of local activity is less compared to previous years from

2010 to 2016.

REGIONAL SEISMIC ACTIVITY

The regional seismicity from April 2006 up to December 2017 clearly shows a cluster of

the seismic activity along the southern part of Iran. All of these earthquakes occur in the crustal

part of the Arabian plate that underlies the Zagros Mountain and Makran region. Figure 12

shows the epicentral distribution of the regional events which are clustered along the Zagros Fold

Belt and the suture boundary between Zagros Fold Belt and Makran subduction zone. The

maximum size of the recorded events is less than 6.4 mb while the focal depth is less than 40km.

SIGNIFICANT RECOREDED LOCAL EARTQHAUKES DURING 2017

All recorded inland local events in 2017 are smaller and none of them are felt. Generally

most of local earthquake activity took place to the south of Masafi. One small event took place

on March 1, 2017 in northern Oman with magnitude 2.6 but no one felt it (Fig. 11).

SIGNIFICANT RECOREDED REGIONAL EARTQHAUKES DURING 2017

Most of felt regional earthquakes took place to the south of Iran in the region

facing the UAE coastal area, specially the northeastern part of UAE as it becomes closer to Iran

area at Hormoz strait. Besides, larger events located along Iran Iraq border and central Iran was

also felt. On November 12 (18:18 GMT), a damaging earthquake with a magnitude 7.3 occurred

along the border region between Iran and Iraq and was felt in most of Gulf Countries. It was one

of the deadliest earthquake in 2017 world widely. This event killed almost 630 people and

injured around 7,460. Most of the reported casualties are in Iran's western province of

Kermanshah, near the epicenter of the earthquake. The earthquake struck the border region at

9:18 pm (GST local time) 30 km southwest of Halabja and nearby the border between Iran and

Iraq.

The second 2017 earthquake felt in UAE that hit on Dec., 1 (02:32 GMT) with a

magnitude 6.0 ML. This event struck Iran`s southeastern Kerman province, causing some injuries

and destroying several houses, adding no deaths had been reported."The quake destroyed some

houses in eight villages but so far there has been no fatalities”,

The Third and Fourth 2017 earthquake felt in UAE are that of December 12 and 13

(08:43, 21:41 GMT) with a magnitude 6.5 and 6.3 ML. These two events struck Iran`s

southeastern Kerman province closer to December 1, 2017 earthquake causing some injuries

without any deaths (Fig. 14).

RECORDED WORLDWIDE SEISMIC ACTIVITY

The DM seismic network recorded many worldwide earthquakes from April, 2006 to

December 2017 (Fig. 15). Most of these activities are clustered along the subduction belt that

called Pacific Ring of Fire. It is an area where large numbers of earthquakes and volcanic

eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it

is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts

and/or plate movements. About 90% of the world's earthquakes and 80% of the world's largest

earthquakes occur along this Ring of Fire. The next most seismic region (5–6% of earthquakes

and 17% of the world's largest earthquakes) is the Alpide belt, which extends from Java to

Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. The Mid-Atlantic

Ridge is the third most prominent earthquake belt.

24

RECORDED WORLDWIDE SEISMIC ACTIVITY DURING 2017

Most of the recorded events took place along the Ring Of Fire in the Pacific Ocean. Much

of largest events took place to the east of Honshu Island (Japan), Eastern Russia and Eastern

Australia and western South American. Part of the activity took place along the Alpide bets that

extends from Iran to Turkey and the Mediterranean region (Fig. 16).

SIGNIFICANT WORLEDWIDE EARTQHAUKES RECOREDED DURING 2017

The most significance events of 2017 are that of Iran-Iraq Border (November 12, M=7.3),

Central Mexico (September 8 (M=8.2) and September 19 (M=7.1), Central Italy (January 18,

M=5.7), Central China (August 8, M=6.5), The number of death of peoples related to these

events are shown on Table 3 while their comparative size to all events of 2017 are shown on

CONCLUSIONS

During 2017, Dubai Seismic Network recorded 933 earthquakes, only 4 events among of

them were located in the northeastern part of UAE, northern Oman. While, most of the regional

seismic activity took place in the southern part of Iran along Zagros fold belt. Most of the

recorded worldwide events are located along the plate boundaries. The rate of local activity in

2017 was slightly less compared to the previous 2010-2016 years.

The source mechanisms of few significant felt local earthquakes (i.e. March, 10,

September 13, 2007, February 12, 2008, February 20, 2011, April 14, 2011 and October 21,

2012) show normal faulting mechanism trending NE to NNE in consistence with Bani Hamid

fault and another fault located north of Huwayalt region. The future cooperation and data

exchange with the neighboring network will led to improve the accuracy earthquakes location in

the Gulf area. Installation of more seismic station in the north part of UAE will increase the

detectabilty of recording the microseismicity and define the local active faults.

RECOMMENDATIONS

Shakecast software should be installed to estimate the strength of shaking and the percent

of loss during any damaging earthquake. This mapped information can be used for emergency

response/ disaster management. Also, it is recommended to install two more VBB station at Jebal

Ali to increase the aperture of DSN. Moreover, the update and evaluation of DB-Safe smart

application is very useful to monitor the Dubai residents awareness about earthquake risk and to

have a powerful tool in case of any earthquake emergency case.
